Harsh Metalloys is a well-respected manufacturer and supplier of Stainless Steel 455 Sheets and Plates, located in Mumbai, India. SS 455 is a martensitic stainless steel alloy that stands out for its impressive corrosion resistance, high strength, and remarkable hardness. It’s particularly popular in applications that demand wear resistance and toughness in moderately corrosive environments. Harsh Metalloys offers these sheets and plates in various sizes, thicknesses, and finishes, all adhering to international standards like ASTM A240. This alloy finds extensive use in the automotive, chemical, petrochemical, and industrial machinery sectors, providing durable, high-performance components.
SS 455 Sheets and Plates generally consist of 13–15% chromium, a maximum of 0.15% carbon, and trace amounts of nickel, molybdenum, and manganese. This unique blend results in excellent hardness (up to 50 HRC after heat treatment), tensile strength between 700 and 900 MPa, and yield strength ranging from 450 to 600 MPa. SS 455 is known for its good wear resistance, toughness, and moderate corrosion resistance, especially in acidic and chloride environments. The sheets and plates are magnetic, can be heat-treated, and offer good weldability and machinability, making them suitable for a wide range of industrial applications.
