SS 15-5Ph Fasteners Manufacturer

SS 15-5 PH Stainless Steel fasteners are manufactured from a precipitation-hardening martensitic stainless steel developed for applications requiring high strength, excellent transverse toughness, and dimensional stability after heat treatment.
SS 15-5 PH fasteners are widely used in aerospace, oil & gas, and precision-engineered assemblies where consistent mechanical performance and reliability are critical.

As a manufacturer of SS 15-5 PH fasteners, we supply components conforming to international standards, suitable for demanding service conditions.

What is SS 15-5 PH Stainless Steel?

SS 15-5 PH is a precipitation-hardening martensitic stainless steel designed to offer better transverse toughness and improved consistency compared to 17-4 PH stainless steel.

The alloy is supplied in a solution-treated condition and then aged (precipitation hardened) to achieve the required combination of strength, hardness, and toughness.
Because of its controlled heat-treatment response, SS 15-5 PH is preferred for critical fasteners used in safety-sensitive applications.

When Should You Choose SS 15-5 PH Fasteners?

SS 15-5 PH fasteners are typically selected when:

  • High tensile strength above 1000 MPa is required

  • Dimensional stability after aging is critical

  • Better transverse toughness than 17-4 PH is needed

  • Fasteners are used in aerospace or critical engineering assemblies

  • Consistent performance across heat-treated batches is essential
