15-5 stainless steel is a martensitic, precipitation-hardening material with chromium, nickel and copper.  It is often a first choice in the aerospace industry for fasteners and structural components.  Its unique structure provides increased toughness and better corrosion resistance than its predecessor, 17-4 PH.  Both inclusion control and a minimized amount of delta ferrite as compared to 17-4 stainless steel contribute to the greater toughness of 15-5.  The alloy is further strengthened by a low temperature heat treatment which precipitates a copper containing phase in the alloy.  15-5 PH is able to meet the stringent mechanical properties required in the aerospace and nuclear industries.

17-7 PH is a precipitation-hardened stainless steel that is well suited for  aerospace and other applications requiring high strength and good corrosion resistance and formability.  Type 17-7PH is a Chromium-Nickel-Aluminum, austenitic stainless steel.  It is the most formable of all PH grades and has the highest strength and hardness.  It is less magnetic than other PH grades and offers minimal distortion upon heat treatment. This material maintains its valuable properties at temperatures up to 800° F (427° C).
