Hemi Metals, located in Hamilton, New Zealand, is a reputable manufacturer and supplier of high-strength Stainless Steel 455 Bars and Rods, specifically designed for advanced engineering and aerospace-grade applications. SS 455 is a martensitic age-hardenable stainless steel celebrated for its remarkable strength, fatigue resistance, and corrosion performance. With rigorous quality control and precise dimensional tolerances in its manufacturing process, these bars and rods ensure dependable performance even under extreme mechanical stress. Hemi Metals caters to industries like aerospace, power generation, defense, and precision engineering, where high load capacity, structural stability, and longevity are essential.
Stainless Steel 455 is composed of about 11–13% chromium and 8–10% nickel, along with copper, molybdenum, titanium, and cobalt to boost its strength and corrosion resistance. This precipitation-hardening grade can achieve incredibly high mechanical strength after heat treatment. Typically, SS 455 bars reach tensile strengths exceeding 1200–1800 MPa, depending on the aging conditions, and they exhibit excellent yield strength and fatigue performance. The material is magnetic, offers good toughness, and boasts corrosion resistance that rivals 304 stainless steel.
