15-5 Stainless Steel Applications: Stainless Steel Alloy 15-5 is used in industrial applications, especially for the aerospace, food service, metalworking, chemical and petrochemical industries. 


15-5 PH stainless steel offers high strength and hardness with excellent corrosion resistance. SS 15-5 can be age-hardened by a low temperature treatment. 15-5 PH stainless steel offers good corrosion resistance, and high strength therefore has been used for aerospace applications.


15-5 PH stainless steel includes high levels of chromium, nickel and copper. Carbon, manganese, phosphorus, sulfur, silicon and columbium plus tantalum may also be present in trace amounts, with each not exceeding 1 percent of the compositional total.

Heat Treatment
15-5 is typically supplied in Condition A, and can be heat treated at a variety of temperatures and times to achieve a wide range of properties. 

Corrosion Resistance

The general level of corrosion resistance exceeds that of Types 410 and 431, and is approximately equal to that of Type 17-4 PH stainless steel as indicated by laboratory tests in both strongly oxidizing and reducing media, as well as by atmospheric exposures. The general level of corrosion resistance is best in the fully hardened condition, and decreases slightly as the aging temperature is increased.
