These Stainless Steel 440C Nuts are made from a high-carbon martensitic stainless steel alloy, which contains about 16–18% chromium along with a significant carbon content. This unique composition allows them to achieve outstanding hardness and strength after undergoing heat treatment. They boast a tensile strength that ranges from 760–1100 MPa, along with excellent resistance to wear and abrasion. While their corrosion resistance is moderate compared to austenitic stainless steels, their impressive mechanical properties—especially hardness and load-bearing capacity—make them ideal for demanding industrial applications where wear and stress are major concerns.
