253MA Stainless Steel Strip
What is 253MA Stainless Steel Strip?
Stainless Steel 253MA is a lean austenitic heat-resistant alloy known for its high strength and exceptional oxidation resistance. Its high silicon, nitrogen, and cerium content contribute to its excellent performance in high-temperature environments. Compared to other alloys, 253MA provides an outstanding combination of high-temperature scaling resistance and creep strength.
Features of 253MA Stainless Steel Strip
Features of 253MA Stainless Steel Strip
253MA stainless steel strip is recognized for its unique combination of properties that make it an excellent choice for various applications. Key features include:
Corrosion Resistance: Although not specifically designed for aqueous corrosion resistance, the high chromium and nitrogen content of this grade provides a pitting resistance comparable to that of 316 stainless steel. However, 253MA has a high carbon content, making it highly susceptible to sensitization from welding or service exposure.
Heat Resistance:
Oxidation - exhibits excellent resistance to air at temperatures up to 1150°C. At elevated temperatures, the steel rapidly forms a thin, highly adherent, and elastic oxide layer. This oxide provides effective protection even under cyclic conditions.
Carburisation - This grade performs well under oxidizing conditions, but alloys with higher nickel content are preferred for reducing atmospheres.
Sulphidation - provides good resistance to sulfur-bearing gases in an oxidizing atmosphere, even with only trace amounts of oxygen present. However, in reducing gases, the protective oxide layer cannot form.
These features make 253MA stainless steel strip a versatile material, widely used in petrochemical industry, presenting a more cost-effective solution.
