Stainless Steel 420 Fasteners consist of 12–14% chromium, about 0.15% carbon, and trace amounts of elements like manganese, silicon, and nickel. This unique blend creates a hardenable martensitic stainless steel that boasts excellent wear resistance and moderate corrosion resistance. These fasteners deliver a tensile strength ranging from 700 to 850 MPa, a yield strength of around 450 MPa, and an elongation rate of 15%, making them perfect for high-strength applications. They can even be heat treated to reach a hardness of up to 50 HRC, striking a balance between mechanical strength and durability in demanding environments.
