440C Stainless Steel Bar
440C stainless steel is a high carbon type of stainless, this is the alloy most often used for knife-making. Can be heat treated for high strength and hardness. 440C stainless steel has greater abrasion and wear resistance for use in bearing and bushing applications. Corrosion resistant only in the hardened condition.
Applications:
