Luois Metals offers top-grade Stainless Steel 15‑7 Mo bars and rods from our Houston plant, providing a nickel‑chromium precipitation hardening alloy with supplementary molybdenum for increased strength and corrosion resistance. Developed in compliance with AMS and ASTM specifications, 15‑7 Mo is the preferred choice in aerospace, defense, and medical industries. Our stocks offer a range of sizes, tempers (H900–H1150), and finishes, with precision cutting and certification services. Supported by responsive service, Luois Metals guarantees rapid delivery of high–performance alloy bars with consistent quality for critical technical applications.
15‑7 Mo contains ~15% chromium, 7% nickel, and ~0.3% molybdenum, with minor additions of aluminum and titanium for precipitation hardening. In aged condition H900, tensile strength is 1,240–1,380 MPa, with yield strength of 1,090–1,240 MPa, and elongation of 5–10%. Hardness is 44–52 HRC. The alloy shows good ductility in solution heat-treated condition and superior corrosion resistance against chloride and oxidizing media. It is weldable and is in compliance with AMS 5643/5644 and ASTM A693/A693M specifications.

Stainless Steel 15-7 MO Bars and Rods are typically heat-treated to achieve optimal strength and hardness. The standard heat treatment involves solution annealing at 1030-1070°C followed by a rapid quenching process to enhance their mechanical properties, such as tensile and yield strength.
Stainless Steel 15-7 MO Bars and Rods generally require minimal maintenance due to their excellent corrosion resistance. Regular cleaning with non-abrasive materials is recommended to maintain their appearance and prevent surface corrosion. For extreme environments, periodic inspections and maintenance are advised to ensure their long-term performance.
15‑7 Mo bars and rods find extensive applications in aerospace parts like flight control components, satellite equipment, and rocket motor casings because of their corrosion resistance and high strength. They are also applied in the medical field with surgical instruments and implants where sterile performance is essential. Downhole tools, valves, and fasteners that operate in corrosive environments are utilized in the oil and gas industry. Athletic equipment like high-performance bicycle components and ski bindings also take advantage of its strength-to-weight ratio and resistance. Its corrosion resistance, high-strength, and good toughness make it suitable for precision and mission-critical components.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
