At Esha Steel, we proudly supply high-quality Alloy Steel WP12 Pipe Fittings to industries across Kolkata and nationwide. Manufactured according to ASME and ASTM standards, these fittings are designed for high-pressure, high-temperature applications, offering reliable performance and long-term durability. Esha Steel ensures precise dimensions, strict quality control, and superior mechanical properties. Trusted by power plants, petrochemical, and industrial sectors, WP12 pipe fittings provide excellent corrosion resistance, toughness, and weldability, making them ideal for connecting and directing critical piping systems in demanding process environments.
Alloy Steel WP12 Pipe Fittings are made from chromium-molybdenum alloy steel with carefully controlled carbon, manganese, phosphorus, sulfur, and silicon content. This alloy composition enhances high-temperature strength, toughness, and resistance to pressure-induced deformation. Mechanically, WP12 fittings offer tensile strength of 485–620 MPa, yield strength of 260–415 MPa, and good elongation with excellent impact resistance. Heat treatment improves hardness, dimensional stability, and creep resistance. Their uniform microstructure ensures reliable weldability, machinability, and mechanical performance, making WP12 pipe fittings ideal for high-pressure, high-temperature industrial and process applications.
