Alloy Steel WP5 is commonly found to have 5% chromium and 0.5% molybdenum with the rest iron and controlled quantities of carbon, manganese, phosphorus, sulfur, and silicon. It offers a minimum yield strength of 205 MPa, tensile strength between 415 and 585 MPa, and elongation of 20% or greater based on dimensions and heat treatment. The chemical composition of the alloy ensures high resistance to oxidation, thermal fatigue, and creep deformation, which makes it a prime candidate for utilization in high-temperature applications in harsh environments. It also has good weldability and formability upon fabrication.
