Khaleed Stainless stands out as a top manufacturer and supplier of high-quality Stainless Steel 253Ma Bars in Riyadh, Saudi Arabia. We specialize in delivering high-performance solutions for industries that demand outstanding heat and corrosion resistance. SS 253Ma is a unique chromium-molybdenum-nitrogen alloyed austenitic stainless steel, crafted for exceptional strength at elevated temperatures and remarkable oxidation resistance. Our 253Ma bars are meticulously engineered to meet international standards, guaranteeing consistent quality, precise dimensions, and a long service life. Perfect for sectors like petrochemical, power generation, chemical, and marine, these bars offer reliability, toughness, and durability in tough, high-temperature, and corrosive environments.
Stainless Steel 253Ma Bars generally consist of 22% chromium, 12% nickel, 0.7% molybdenum, 0.3% nitrogen, and 0.15% carbon, along with small amounts of manganese and silicon. They boast a tensile strength of around 700 MPa, yield strength of 290 MPa, an elongation of 30%, and a Brinell hardness of about 215 HB. This alloy composition ensures excellent high-temperature strength, creep resistance, and oxidation resistance up to 1100°C. Additionally, SS 253Ma bars provide outstanding weldability, toughness, and resistance to thermal fatigue, making them perfect for demanding industrial applications.
