Brian Fasteners, with headquarters in Houston, USA, provides Stainless Steel 17‑7 PH bars and rods manufactured through precision forging, cold rolling, and heat treatment processes. The company provides strong, corrosion-resistant products with close tolerances and uniform finishes. Every bar is subjected to dimensional and metallurgical testing to verify quality. Serving the aerospace, spring manufacturing, and fastener markets, Brian Fasteners offers custom sizes, rapid delivery, and technical assistance. Their selection of 17‑7 PH bars and rods provides dependable material for applications that require precipitation-hardening durability and strength in challenging American industrial conditions.
17‑7 PH Stainless Steel has ~17% chromium, 7% nickel, with aluminum and titanium additions, and carbon <0.07%. Aged it has tensile strength up to 1,100 MPa, yield strength about 900 MPa, and elongation 10–20%. Corrosion resistance is about that of 304, and precipitation hardening provides high strength and good toughness. Its properties can be tailored through heat treatment to fit particular service conditions.
