With a perfect blend of hardness, corrosion resistance, and precise dimensions, Stainless Steel 420 Fasteners are perfect for industries like automotive, construction, marine, oil & gas, and heavy engineering, both in Australia and around the world.
Stainless Steel 420 Fasteners consist of 12–14% chromium, along with carbon, manganese, silicon, and nickel, which gives them a martensitic microstructure. These fasteners can be hardened through heat treatment, achieving tensile strength between 700–900 MPa and hardness levels of 40–50 HRC. They boast excellent wear resistance, decent corrosion resistance, and high mechanical stability under stress. This material guarantees reliable performance in moderately corrosive and high-temperature settings, making Stainless Steel 420 an outstanding choice for precision fastening applications that demand both strength and durability.
