Vishal Flanges is a reputable manufacturer and supplier of Stainless Steel 253MA Flanges based in Delhi, India. They provide high-performance solutions tailored for high-temperature and oxidation-resistant applications. The 253MA alloy is an austenitic stainless steel specifically designed for exceptional heat resistance, boasting impressive strength, good corrosion resistance, and enhanced creep properties. These flanges are perfect for extreme thermal environments and are crafted according to international standards like ASME B16.5, ANSI, and DIN. Vishal Flanges prioritizes precision manufacturing, durability, and dimensional accuracy, making their flanges ideal for critical applications in sectors such as petrochemical, power generation, and metallurgy.
Stainless Steel 253MA Flanges mainly consist of chromium (20–22%), nickel (10–12%), silicon (1.4–2.0%), along with trace amounts of rare earth metals to boost oxidation resistance. This alloy offers a tensile strength of about 600 MPa and a yield strength of 310 MPa, along with outstanding high-temperature mechanical properties. Its remarkable resistance to oxidation at temperatures up to 1150°C, paired with excellent structural stability and toughness, makes it perfect for continuous use in thermal processing equipment. Additionally, 253MA withstands sulfuric, phosphoric, and nitric acids, making it suitable for chemically aggressive environments.
