Al Shakru Sheets and Plates, a highly regarded manufacturer and supplier based in Dubai, UAE, focuses on high-performance Stainless Steel 440C Circles that are notable for their exceptional hardness, wear resistance, and corrosion resistance. Engineered with precision and longevity in mind, these circles are ideal for applications requiring strength and dependability in demanding industrial and engineering environments. Manufactured to comply with international standards, Al Shakru Sheets and Plates’ Stainless Steel 440C Circles deliver superb dimensional accuracy, toughness, and abrasion resistance. Their remarkable mechanical properties make them well-suited for high-precision tooling, structural components, and machinery parts, guaranteeing durable performance wherever strength, dependability, and wear resistance are essential.
Stainless Steel 440C Circles are composed mainly of iron, with roughly 16–18% chromium and 0.95–1.20% carbon, plus minor quantities of manganese, silicon, and molybdenum. This high-carbon martensitic stainless steel provides remarkable hardness, a tensile strength in the range of 760–1100 MPa, yield strength from 450–750 MPa, and outstanding wear resistance. On top of that, the material delivers solid corrosion resistance, toughness, and dimensional stability, which makes it well-suited for high-precision, high-stress, and high-wear applications.
