SS2686 440C stainless steel powder

440C Stainless Steel Powder Description

440C Stainless Steel Powder is the stainless steel from the 400 series that has the highest carbon content. It is employed in applications requiring high hardness, wear resistance and corrosion resistance. Stainless steel 440 is available in four variants: 440A, 440B, 440C and 440F. With the exception of 440F, the other 440 steels differ in their carbon content. 440C is the most widely used variant, and 440F is a higher version of 440C with an added S element. The 440C stainless steel exhibits better edge retention when subjected to proper heat treatment.

Applications of 440C Stainless Steel Powder

• Powder Metallurgy (PM): 440C stainless steel powder is used in powder metallurgy to manufacture stainless steel components that require high strength and wear resistance. It is employed in applications demanding specific hardness and corrosion resistance, for example in cutting tools, knife blades and wear parts in the automotive, aerospace and defence sectors.
• Additive Manufacturing (AM): The powder is used in additive manufacturing processes such as selective laser melting (SLM) or electron beam melting (EBM) to produce complex stainless steel parts with well-defined mechanical properties. It is applied in fields including aerospace, medical engineering and tool making.
• Bearings and Balls: 440C stainless steel powder is used for the manufacture of precision bearings, ball bearings and bearing components. Its high hardness and corrosion resistance meet the requirements for applications that demand reliable operation, extended service life and resistance to harsh environments.
• Surgical and Medical Instruments: The powder is utilised in the manufacture of surgical and medical instruments due to its corrosion resistance, hardness and biocompatibility. It is used for producing surgical blades, dental instruments, orthopaedic implants and other medical devices.
• Mould and Die Inserts: 440C stainless steel powder is applied in the production of mould and die inserts, where high wear resistance and dimensional stability are needed. It is used in plastic injection moulding, die casting and various forming processes.
• Industrial and Special Applications: The powder is suitable for industrial and specialised applications that require high hardness, wear resistance and corrosion resistance. Examples include valve components, nozzles, gears and cutting tool inserts.
