These products are specifically crafted for applications that demand outstanding strength, toughness, and resistance to corrosion. Adhering to strict AMS, ASTM, and ASME standards, these precipitation-hardening stainless steels provide remarkable mechanical properties and maintain their shape after heat treatment. You can find Stainless Steel 15-7 MO Bars and Rods in various diameters, lengths, and conditions to satisfy even the toughest engineering needs. Industries like aerospace, petrochemical, chemical processing, defense, and high-performance manufacturing trust George Metals for their consistent quality, expert assistance, and dependable supply.
Stainless Steel 15-7 MO Bars and Rods are made from chromium-nickel-molybdenum precipitation-hardening alloys, featuring around 15% chromium, 7% nickel, and 2.5–3% molybdenum, along with aluminum for added strength. In their annealed state, they boast a tensile strength of about 965 MPa, which can soar to over 1380 MPa after heat treatment. Yield strength can surpass 1275 MPa while still offering good ductility and fracture toughness. This alloy is highly resistant to oxidation, stress corrosion cracking, and moderate corrosion in various environments. It can be easily shaped when annealed and hardened through a simple, low-temperature heat treatment for high-strength applications.

Stainless Steel 15-7 MO Bars and Rods are ideal for applications that require high strength, fatigue resistance, and moderate corrosion protection. Aerospace manufacturers often choose them for structural components, diaphragms, springs, and fasteners that need to be lightweight yet strong. In the petrochemical and chemical processing sectors, they are utilized for pressure vessels, process equipment, and shafts that face mildly corrosive environments. Defense applications include ordnance parts and high-strength hardware. Additionally, general engineering makes use of 15-7 MO for precision-machined parts and components that need to withstand wear.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
