15-5 stainless steel is a martensitic, precipitation-hardening alloy containing chromium, nickel, and copper. It is a popular choice in the aerospace industry for fasteners and structural components due to its enhanced toughness and superior corrosion resistance compared to 17-4 PH. This improved performance is achieved through better inclusion control and reduced delta ferrite content.
The alloy is further strengthened by a low-temperature heat treatment that precipitates a copper-containing phase. 15-5 PH meets the stringent mechanical property requirements of the aerospace and nuclear industries and is also widely used in food processing, paper, and general metalworking industries.
Amardeep Steel supplies 15-5 PH Stainless Steel Bar, also known as AMS 5659 or UNS S15500. This material is a martensitic, precipitation-hardening stainless steel alloy with approximately 15% chromium and 5% nickel, plus copper. It is known for its high strength, hardness, and excellent corrosion resistance, making it a preferred choice in the aerospace industry for fasteners and structural components.
Compared to its predecessor, 17-4 PH, 15-5 PH offers better toughness, especially in larger cross-sections, and improved mechanical properties. This is due to a refined microstructure achieved through a remelting process, which also enhances its fabrication properties and corrosion resistance. The inclusion control and minimized delta ferrite content further contribute to its superior transverse toughness and ductility.
