410/420/440C Stainless Steel Bar/Rod

410, 420, and 440C all belong to martensitic stainless steel (400 series). Their core characteristics are “chromium content, heat-treatable strengthening, and high hardness”, which distinguishes them from the “non-strengthening” of ferritic stainless steel (such as 430) and the “non-magnetic and highly corrosion-resistant” of austenitic stainless steel (such as 304). They are mainly used in scenarios with clear requirements for hardness and wear resistance, such as cutting tools, bearings, and precision mechanical parts.
