These bolts are primarily made of iron, featuring 12–14% chromium and a minimum carbon content of 0.15%. This composition allows for heat treatment, which enhances their hardness. After proper heat treatment, they can reach a tensile strength of around 700–900 MPa and a hardness of up to 50 HRC. While SS 420 provides moderate corrosion resistance—especially in dry or mildly corrosive environments—it truly shines in applications that require high mechanical strength, edge retention, and abrasion resistance.
