With over 20 years of experience, Best Stainless supplies 15-5 PH stainless steel for a variety of industries including aerospace, petrochemical, and pulp & paper factories. 15-5 PH stainless steel bar and block is a precipitation-hardening martensitic stainless steel designed to have greater toughness than 17-4 PH stainless steel. It is used in applications requiring better corrosion resistance and transverse properties compared to other similar martensitic grades. The strength and toughness desired can be altered by the temperate range in the heat treatment process.
Our 15-5 stainless steel comes in a range of grades and shapes used for many applications. We have an extensive stock of shapes including 15-5 stainless steel round bar, hex bar, flat bar, and square bar, as well as boat shaft, pump shaft, and precision-cut blocks. Our block offerings provide ideal stock for machining complex components while maintaining the material's superior mechanical properties.
Below you will find typical applications of 15-5 PH stainless steel as well as the metals' composition and mechanical properties. Learn more about the value-added services that we offer to help you expedite the current job you have at hand.
