Weston Stainless, a Midland, UK-based company, is a reputed supplier of premium stainless steel products such as Stainless Steel 420 Sheet and Plates. The sheets and plates are produced using grade 420 stainless steel, a martensitic steel featuring high strength, good hardness, and excellent wear resistance. The material provides good corrosion resistance when it is hardened or polished and can find applications in demanding industrial uses. Being in various shapes, thicknesses, and finishes, Stainless Steel 420 Sheet and Plates are found in numerous applications that demand high toughness, hardness, and mechanical wear resistance with moderate corrosion resistance.
Stainless Steel 420 Sheet and Plates consist of iron with 12-14% chromium for resistance to corrosion, 0.15-0.40% carbon for hardness, and minor amounts of manganese, silicon, and sulfur. They provide a tensile strength of as high as 700 MPa, yield strength of 345 MPa, and an elongation of about 20%. The density is about 7.75 g/cm³, and the melting point is roughly 1450°C. The alloy has good hardness and wear resistance, so it is suitable for those applications demanding strength and durability.
