Weston Stainless based in Midland, UK is a reliable stainless steel products supplier with high quality stainless steel offering hard and resistant-to-corrosion solutions in industrial applications. Of its available offerings, the Stainless Steel 455 Bar ranks highly in its excellent strength, resistance to corrosion, and fine hardness. Of Grade 455 classification, it is offered in many shapes including round, square, and hexagonal shapes accommodating multiple industry requirements. Made of martensitic stainless steel, it has high toughness, good fatigue strength, and improved durability, and thus is an optimum fit for use where superior mechanical performance and strong resistance to aggressive environments are needed.
Stainless Steel 455 Bar consists mostly of iron with a high content of chromium (11-12.5%) and nickel (7.5-9.5%), being highly corrosion-resistant. It may also include molybdenum, titanium, and carbon, which further improve its hardness and strength. This alloy has a tensile strength of around 1380 MPa, yield strength of about 1250 MPa, and elongation of 10%. It has a physical property of density of 7.8 g/cm³, good thermal conductivity, and very good resistance to stress corrosion cracking, which makes it ideal for high-performance engineering applications.
