What is 15-7 PH Stainless Steel?

15-7 PH stainless steel is a strong type of stainless steel made mainly from chromium and nickel, with a small amount of aluminum added. The "PH" means precipitation hardening, which is a special heat treatment that makes the metal much stronger and harder while keeping it resistant to rust and corrosion.

This stainless steel works really well when turned into fasteners like nuts, bolts, washers, and stud bolts. It holds its shape, stays tough, and doesn’t wear out easily. Manufacturers can make it in different finishes by using heat or cold working, depending on what your project needs.

Engineers, manufacturers and industries that need strong, long lasting fasteners in hard assemblies. Manufacturers shape and treat the alloy using methods like cold drawing, heat treatment, and forging, depending on the type of fastener.

They are used globally across sectors like aerospace, marine, chemical, medical, and oil & gas industries. When you need both high strength and corrosion resistance, especially in tough or high-temperature conditions. Common standards include ASTM A564, A693, A705, and ASTM F2281 for fasteners.
