Luke Steel is one of the most prominent manufacturers and suppliers of Alloy Steel WP11 Pipe Fittings in Houston, USA. Renowned for offering products according to international engineering standards, Luke Steel has established itself as a strong market presence in the USA and Middle East. With attention to precision manufacturing, on-time shipping, and customer satisfaction, the company services a broad range of industries such as oil & gas, petrochemicals, and power generation. These pipe fittings are designed for maximum durability and efficiency, thus Luke Steel is a go-to name for high-performance alloy steel solutions in critical and high-pressure industrial applications.
Alloy Steel WP11 Pipe Fittings consist mainly of 1.00–1.50% Chromium and 0.44–0.65% Molybdenum, which ensure better corrosion resistance, thermal stability, and mechanical strength. Having a minimum tensile strength of 415 MPa and minimum yield strength of 205 MPa, the fittings also possess good elongation properties for ductility. Created to operate at high pressure and high temperature, the fittings ensure long-term structural integrity. Their strong structure guarantees efficient performance under stress-loaded conditions and hence is a choice for critical operations and long-term applications in high-demanding industries.
