Saif Sheets and Plates is a reliable manufacturer and supplier in Muscat, Oman, offering premium-quality Stainless Steel 422 Circles for industries that require exceptional strength, heat resistance, and long-term durability. Known for its martensitic composition and superior high-temperature performance, Stainless Steel 422 is widely used in demanding industrial environments. Saif Sheets and Plates ensures every product meets strict global quality standards, delivering precision, accuracy, and dependable service life. With a strong customer-focused approach, the company supports sectors such as power generation, aerospace, petrochemicals, and engineering with robust stainless steel circle solutions tailored for challenging applications.
Stainless Steel 422 Circles are composed of iron alloyed with 12–14% chromium and 0.20–0.35% carbon, giving the grade exceptional strength and hardenability. Small additions of molybdenum, tungsten, and vanadium enhance high-temperature stability, wear resistance, and mechanical performance. SS 422 typically offers a tensile strength of 690–965 MPa and yield strength around 480–655 MPa, depending on heat treatment. With excellent creep resistance and oxidation stability at elevated temperatures, this alloy is well-suited for high-stress, high-heat industrial environments.
