Starc Metals stands out as a top-notch manufacturer and supplier of Stainless Steel 15-7 MO Bars and Rods right here in Canberra, Australia. We take pride in offering premium-grade products that are crafted for high-performance applications. Our 15-7 MO stainless steel bars and rods are made from precipitation-hardened alloys, which means they pack a punch with their high strength, toughness, and impressive corrosion resistance. Thanks to their excellent formability and stability during heat treatment, these materials are perfect for critical components that face tough operating conditions. At Starc Metals, we guarantee precise dimensions, a fantastic surface finish, and dependable mechanical integrity, making our products a go-to choice for the aerospace, chemical, and marine engineering sectors where durability and performance are non-negotiable.
When it comes to the composition of our Stainless Steel 15-7 MO Bars and Rods, you’ll find 14–16% chromium, 6.5–7.75% nickel, 2–3% molybdenum, and a maximum carbon content of 0.09%. We also add a touch of aluminum (0.75–1.5%) to enhance precipitation hardening. This alloy boasts a tensile strength of up to 1310 MPa and a yield strength of around 1170 MPa in the TH1050 condition, along with remarkable fatigue and creep resistance. Its unique blend of austenitic and martensitic phases gives it exceptional hardness, stability, and corrosion resistance, even when faced with high temperatures and mechanical stress.

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.
You’ll find Stainless Steel 15-7 MO Bars and Rods widely used in aerospace components, chemical processing equipment, and marine hardware, all thanks to their outstanding strength-to-weight ratio and resistance to corrosion. They’re also perfect for making springs, fasteners, diaphragms, pressure vessels, and structural parts where high mechanical strength and precise dimensions are crucial. Plus, the alloy’s ability to resist oxidation and scaling at elevated temperatures makes it ideal for critical applications in turbines, jet engines, and high-pressure systems that demand long-lasting durability and reliability.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
