15-5PH Stainless Steel

WLD Steel is a leading manufacturer, supplier and exporter of the stainless steel 15-5 PH available in a number of different sizes and forms including bar, plate and wires. We mainly stocks15-5 in annealing condition. 15-5 PH is a  precipitation-hardening Martensitic stainless steel that developed base on 17-4PH steel and is the Ferrite-free version of Type 17-4 PH stainless steel. It provides high strength, good corrosion resistance, good mechanical properties and toughness. It has a similar application with  17-4 PH steel, both of them can be used where requiring better corrosion resistance and transverse properties such as aerospace, chemical, petrochemical, food processing, paper and general metalworking industries.
