WHAT IS HEAT & SURFACE TREATMENT? Heat and Surface Treatment is the collective name for a method performed on metals and non-metals to meet certain criteria. These criteria can either be for aesthetic reasons, but are most done to increase durability by: PREVENT WEAR AND TEAR ON THE MATERIAL PROTECTS THE COMPONENT FROM ELEMENTS OF NATURE ELECTRICAL INSOLATION WHY HEAT & SURFACE TREATMENT? Products are heat and surface treated to produce beautiful, durable, and strong components. CORROSION When a metal is in its natural form before it is mined, it has different mineral forms. When the metal is machined and the minerals are refined into a component, it’s not as stable as in its mineral form. Rust, also called corrosion is nature's way of getting the metal to return to its natural mineral form. Surface treatment means that you somehow create a protective layer between the raw surface of the component and the elements of nature, to prevent the minerals from breaking down. CORROSION PROTECTION ELECTRICITY & HEAT It is not only the forces of nature that can break down metals, electricity and high temperatures also affects metal in a negative way. Most metals conduct electricity, which is good for purposes such as electrical cables, but in some cases, you don’t want the metal to conduct current. To prevent the metal from conducting current, the metal can be covered with a surface that does not penetrate the electrons and insulates the component. Electrolytic surface treatment provides a protected film of chromium, nickel, or zinc. If you want the component to conduct electricity well, you can treat the material with a surface such as silver or gold, which is very lively. ELECTRICAL PROTECTION FINISH When a component is treated to be stronger and more durable, it can look ugly. Toughness is not always the only criteria. Since many of our finished products reach consumers, aesthetics is also important. The most important thing is to protect the component from the elements of nature, but in some cases it’s just as important that the product is exposed in a way that satisfies the viewer’s eye. HOW DO I GET A NICE FINISH ON THE COMPONENT? HARDNESS & TOUGHNESS Some base materials do not meet the criteria found on the component when it comes to how strong it should be. Therefore, the component can be given new properties, where they can become harder or tougher via heat treatment. HOW DO I MAKE THE MATERIAL HARD? SOFT & SMOOTH SURFACES When a component is machined, sharp edges can appear. Then you must polish these sharp edges, so they become smoother. While doing this, the mechanical component becomes softer and nicer to hold. HOW DO YOU MAKE THE SURFACES SMOOTH AND SOFT? CLEAN SURFACES A CNC machine uses oil to cool the tools as they cut the raw material. This means that the mechanical component is oily, but also has residues such as swarf and chips, or other particles of matter that the naked eye cannot see. It is then important to clean the product, so it can undergo the next process or be delivered to the customer. Through cleaning, the component also receives thin rust protection that protects it during transportation or storage. HOW TO GET THE COMPONENT CLEAN? HEAT & SURFACE TREATMENT METHODS Which surface treatment you choose for your product is defined by the purpose of the use. It is important already in the engineering stage of a product, to decide how it should be treated or not. HARDENING SURFACE TREATMENT GRINDING DRUM POLISHING WASHING WHAT IS SURFACE TREATMENT? Surface treatment is a method where you apply a thin layer of chemical liquid on the material's surface. This chemical liquid then creates a protective film. Depending on what you want to protect and what material you have for your component, this film can provide different protection: ELECTRO-GALVANIZING PHOSPHATATION ANODISING REQUEST A QUOTE SURFACE TREATMENT WHAT IS DRUM POLISHING? Drum polishing is a method where you put the components in a drum and spin them together with a liquid called compound and stones called chips. With the help of the compound and the chips, you can: SMOOTH SHARP EDGES POLISHING OF SURFACES FOR BETTER SURFACE EVENNESS AND FINISH CLEANING CORROSION PROTECTION DEGREASING REQUEST A QUOTE DRUM POLISHING WHAT IS GRINDING? If a mechanical component has tight tolerances the CNC lathe has difficulty keeping up with. Then you have to use a machine that is able to keep such tight tolerances, and that is a grinder. CIRKULAR GRINDING HOLE GRINDING CENTERLESS GRINDING REQUEST A QUOTE GRINDING WASHING WHY IS WASHING IMPORTANT? By alkaline washing your mechanical components, you can remove unwanted particles such as: OIL SWARFS AND CHIPS DIRT REMOVE OIL REMOVE PARTICLES NON-PERMANENT CORROSION PROTECTION REQUEST A QUOTE HARDENING & HEAT TREATMENT Hardening is a method where the material is heated to a high degree in a furnace to gain new properties that it did not have before. For example, becoming harder, tougher, and more durable. The most common methods of heat treatment are: TEMPERING VACUUM CURING SET CURING HARDENING CARBONITRATION NITRO CARBURETION + AFTER OXIDATION REQUEST A QUOTE HARDENING & HEAT TREATMENT THE SPIDER IN THE WEB Through our network of suppliers in our area , we can provide heat and surface treatment for the components we machine.

HARDENING & HEAT TREATMENT SEE OUR HARDENING METHODS HERE WHAT DIFFERENT HARDENING METHODS ARE THERE? What gives the material better properties has to do with the dislocation mobility being redirected in the material. Dislocation is different from material to material and therefore also requires different types of methods to succeed in getting the properties you want. THE HARDENING METHODS AVAILABLE ARE: TEMPERING VACUUM HARDENING SET HARDENING HARDENING CARBONITRIDING NITROCARBURATION + AFTEROXIDATION VACUUM HARDENING Vacuum hardening is a thermal treatment method where tool steel heats the surface access to oxygen and gives hard properties to the material. After the material has been vacuum cured, it must be tempered . Depending on whether you want a nice surface without discoloration, you can make the tempering in the vacuum oven. If there are no specific surface requirements or requirements for the appearance, then you can use the cheaper method, to tarnish in an ordinary tempering furnace. MATERIAL THAT CAN BE VACUUM HARDENING The materials that can be vacuum cured are tool steel in the specifications: SS2260 SS2310 SS2312 SS2303 READ MORE ABOUT TOOL STEEL HERE BENEFITS OF VACUUM HARDENING No oxides present No oxygen presents Limited distortion Clean and bright results DISADVANTAGES OF VACUUM HARDENING Time-consuming Sensitive to disturbances Must be handled correctly and carefully, which requires knowledge TEMPERING Tempering is a process that is usually performed according to some type of hardening method. When you use some type of hardening method, you maximize certain types of properties that the method offers. This makes other characteristics less good. The purpose of tempering as a post process is to change the properties of the material that are less good to become better. MATERIAL Materials that can be tempered: SS2260 SS2310 SS2312 READ MORE ABOUT TOOL STEEL HERE BENEFITS Provides new desired properties Reduce the risk of cracking DISADVANTAGES Provides an extra process for the heat treatment, which increases prices and delivery times. All hardened steels must be tempered, with a few exceptions. If the tempering does not take place in a vacuum oven, there will be a color change at degrees above 150-200 degrees.

POSOXIZATION SET HARDENING The set hardening task is to apply a hard surface to the soft and easy-to-work steel. These types of steel are too soft and ordinary hardening would not have any effect. By adding carbon, this soft steel also gets the hard properties you want. MATERIAL THAT CAN BE SET HARDEND The materials that can be set hardened are low-alloy steels in the specifications: SS1370 SS2172 SS2514 SS2511 SS1922 SS1914 READ MORE ABOUT ALLOY STEEL HERE BENEFITS OF SET HARDENING Good for low-alloy steels High wear resistance High bearing capacity Good fatigue strength The core retains its toughness DISADVANTAGES OF SET HARDENING Rugged surface Voltages may occur Finishing may be required CARBON NITRIDING Carbon nitriding is a variant of case hardening used for low-alloy steels. Gives a hard surface layer to an already soft and easy-to-work material MATERIAL The materials that can be carbonitrided are light alloy steels in the specifications: SS1312 SS2132 S355 OVAKO 280 SS1914 READ MORE ABOUT TOOL STEEL HERE BENEFITS OF CARBON NITRIDING Easy Quick Cheap Unalloyed steels can be hardened High wear resistance DISADVANTAGES OF CARBON NITRIDING Shape defect with a rough surface Finishing may be required BENEFITS OF HARDENING Can be combined with several hardening methods that create unique properties Method that works for most steels DISADVANTAGES OF HARDENING The balance between toughness and hardness must be made with the choice of steel specification in mind, otherwise you will not get the desired properties HARDENING The task of hardening is to optimize and find the best mixture for toughness and hardness. Steel components are usually improved when the hardness is weighed against the toughness. Hardness improves: Life span Durability Load capacity Toughness reduces the risk of: Breakdowns Crisp fracture MATERIAL AS CAN BE HARDEND Most steels can be hardend, but the most common are: SS2140 SS2090 SS2550 SS2258 SS2541 SS1770 READ MORE ABOUT ALLOY STEEL HERE BENEFITS Provides new desired properties Reduce the risk of cracking DISADVANTAGES Provides an extra process for the heat treatment, which increases prices and delivery times.

STEEL ALLOY STEEL STAINLESS STEEL MATERIAL READ MORE ABOUT STEEL HERE WHAT IS HARDENING AND HEAT TREATMENT? Hardening is a method where material is heated to a high degree in an oven to get new properties that it did not have before. The characteristics will change to increased: HARDNESS STRENGTH TOUGHNESS SUSTAINABILITY The curing of the material takes place in the cooling process itself, the faster it cools down, the harder the material becomes and vice versa. NITROCARBURIZATION + POST OXIDIZATION Nitrocarburization + post oxidation also called nitro black, supplies the component with nitrogen and carbon. This creates an oxide film on the surface, which is opaque. MATERIAL The materials that can nitrocarburized + post oxidized are: ALLOY STEEL CARBON STEEL TOOL STEEL READ MORE ABOUT TOOL STEEL HERE BENEFITS OF NITROCARBURIZATION + POST OXIDATION No shape changes Gets a black surface Corrosion protection Increases durability prevents scratches DISADVANTAGES OF NITROCARBURIZATION + POST OXIDATION The black color can vary depending on the type of steel Expiring effect on the already hardened steel The surface layer is thin and the component can therefore not be processed afterward
