Houston, USA-headquartered Brian Fasteners offers Stainless Steel 17‑7 PH hex bars and hex rods via precision forging and heat treatment. The precipitation-hardening alloy provides exceptional mechanical strength with resistance to corrosion. Brian Fasteners ensures each hex bar will have close dimensional tolerances and metallurgical requirements. Supplying aerospace, fastener, and tooling industries, the company provides custom hex profiles, fast shipping, and technical assistance. As a specialist supplier, Brian Fasteners provides consistent performance of 17‑7 PH hex bars in high-strength, corrosion-resistant design applications throughout American industrial markets.
Stainless Steel 17‑7 PH is a precipitation hardening alloy containing around 17% chromium, 7% nickel, and minor amounts of aluminum and titanium. Carbon levels are below 0.07%. Upon aging, it can attain tensile strength up to 1,100 MPa, yield strength of about 900 MPa, and elongation of 10–20%. It exhibits top corrosion resistance equal to 304 with high toughness and strength. Heat treatment allows the mechanical properties to be tailored as per the requirements of the application.
