Luke Steel is a trusted manufacturer and supplier of Alloy Steel WP12 pipe fittings, proudly based in Houston, USA. With a solid foothold in the industrial piping market, Luke Steel specializes in delivering high-performance alloy steel fittings that are designed to meet ASTM A234 WP12 specifications. The company caters to essential industries like power generation, petrochemicals, refineries, and high-temperature processing, offering a diverse selection of seamless and welded pipe fittings, including elbows, tees, reducers, and caps. Renowned for their precision manufacturing, top-notch quality control, and a customer-first approach, Luke Steel ensures reliable solutions for challenging pressure and temperature conditions, both domestically and globally.
Alloy Steel WP12 pipe fittings are primarily made up of chromium (9%) and molybdenum (1%), with the rest being iron and trace amounts of carbon, manganese, phosphorus, sulfur, and silicon. This Cr-Mo alloy is known for its impressive mechanical strength, good corrosion resistance, and stability at high temperatures. Typically, the mechanical properties include a tensile strength ranging from 415 to 585 MPa, yield strength around 205 to 275 MPa, and an elongation of 20% or more. These fittings excel in high-pressure and thermal cycling situations, making them ideal for applications involving steam, superheated fluids, and harsh industrial environments that demand long-lasting durability and reliability.
