Alloy Steel WP22 Buttweld Fittings are primarily made up of Chromium (2.00–2.50%) and Molybdenum (0.87–1.13%), along with carefully balanced levels of carbon, manganese, phosphorus, sulfur, and silicon. These components significantly boost corrosion resistance, heat tolerance, and mechanical strength. Typically, these fittings boast a tensile strength ranging from 415 to 585 MPa, a yield strength of at least 205 MPa, and a minimum elongation of 20%. They also exhibit impressive hardness and resistance to stress rupture, making them well-suited for high-temperature applications in power plants and refineries. At Zain Fittings, we ensure that all our products meet the ASTM A234 WP22 standards.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
