Based in Delhi, India, Daksh Sheets and Plates is a well-known producer and supplier with a focus on premium stainless steel 455 circles (UNS S45500). This cutting-edge, age-hardenable, martensitic stainless steel is incredibly strong, corrosion-resistant, and simple to fabricate. Stainless Steel 455’s chemical makeup, which comprises 11–12.5% chromium, 7.5–9.5% nickel, and 1.5–2.5% copper, makes it perfect for demanding applications in the petrochemical, medical device, and aerospace industries. Daksh is a reliable partner for industries needing long-lasting and high-performance stainless steel components because they guarantee precise manufacturing and prompt delivery.
About 11–12.5% chromium, 7.5–9.5% nickel, and 1.5–2.5% copper make up the martensitic, age-hardenable alloy known as stainless steel 455 (UNS S45500). Tiny amounts of carbon (0.07%), manganese, silicon, and phosphorus are also present. Excellent strength and moderate corrosion resistance are provided by this composition. Mechanically, SS 455 has a yield strength of 690–950 MPa, a tensile strength of 860–1100 MPa, and an elongation of roughly 10%–15%. Applications needing high strength and toughness, like aerospace, petrochemical, and structural components exposed to moderately corrosive environments, can benefit from its good hardness following heat treatment.
