15-5 PH Stainless Steel, an advanced variant of 17-4 PH, is a martensitic precipitation-hardening stainless steel with superior mechanical strength, excellent corrosion resistance, and good fabricability. These sheets are particularly sought after in industries such as aerospace, marine, chemical processing, nuclear, petrochemical, and general engineering due to their exceptional mechanical properties and toughness in both longitudinal and transverse directions. This steel is known for its ability to achieve high strength and hardness through heat treatment, while maintaining excellent weldability and corrosion resistance.

Hindco Steel And Alloys provides 15-5 PH Sheets that offer consistent performance in both annealed and aged conditions. These sheets are easy to machine and can be readily welded using standard practices. They are resistant to scaling and oxidation at elevated temperatures and perform well under dynamic and impact loads. Whether your requirement is for aerospace components, pressure vessels, or structural parts in corrosive environments, our 15-5 PH Stainless Steel Sheets deliver unmatched strength and dependability.

Our 15-5 PH Sheets conform to ASTM A693 Grade 15-5PH and carry the UNS S15500 universal designation. These materials are heat-treated to Condition H1025, H1075, H1100, and other tempers to suit demanding performance requirements. Being a chromium-nickel-copper stainless steel, 15-5 PH offers enhanced toughness and corrosion resistance compared to standard martensitic stainless steels. This makes it a preferred material choice for critical components in aerospace structural parts, turbine blades, shafts, fittings, fasteners, and high-performance machinery.
