Stainless Steel 420 Bolts are crafted from a martensitic stainless steel grade that contains about 12–14% chromium, a minimum of 0.15% carbon, along with small amounts of manganese, silicon, and phosphorus. This blend gives them remarkable hardness and decent corrosion resistance. In terms of mechanical properties, they feature a tensile strength ranging from 700–850 MPa, a yield strength of 345 MPa, an elongation of 15%, and can reach hardness levels of up to 50 HRC after heat treatment. SS 420 bolts are known for their high wear resistance and ability to maintain structural integrity in moderately corrosive settings, making them perfect for critical fastening tasks that require both strength and durability.
