Khaleed Stainless stands out as a top-notch manufacturer and supplier of high-quality stainless steel products in Riyadh, Saudi Arabia, with a special focus on Stainless Steel 253MA Pipe Fittings. These fittings are celebrated for their remarkable high-temperature strength and outstanding resistance to corrosion, all crafted to meet rigorous international standards. Khaleed Stainless caters to essential industries like power generation, petrochemical, and chemical processing, delivering reliable and durable piping solutions. With a strong dedication to quality, precision, and timely delivery, the company has earned a stellar reputation throughout Saudi Arabia and the GCC for its excellence in stainless steel pipe fittings.
The Stainless Steel 253MA Pipe Fittings from Khaleed Stainless are primarily made up of chromium (22–23%) and nickel (12–14%), with additional molybdenum and nitrogen to boost oxidation resistance and mechanical strength at high temperatures. These fittings excel in creep resistance and maintain their structural integrity even in continuous service at temperatures reaching 1100°C. They boast a tensile strength of about 550 MPa and a yield strength of around 250 MPa, along with exceptional resistance to carburization and thermal fatigue. This makes them perfect for tough environments that involve thermal cycling and aggressive chemicals.
