Sadiki Metals, based in Kinshasa, Congo, has made a name for itself as a top-notch manufacturer and supplier of high-quality Stainless Steel 15-7 MO Bars and Rods. The company is committed to delivering precision-engineered stainless steel products that adhere to the highest international standards for quality and performance. Known for their exceptional strength, impressive corrosion resistance, and remarkable heat-treatable properties, Sadiki Metals’ Stainless Steel 15-7 MO Bars and Rods are crafted using cutting-edge technology and premium raw materials, making them perfect for demanding applications in the aerospace, petrochemical, marine, and mechanical industries, both in Congo and around the globe.
These Stainless Steel 15-7 MO Bars and Rods contain about 15% chromium, 7% nickel, and 2–3% molybdenum, along with small amounts of aluminum to enhance precipitation hardening. This distinctive chemical makeup gives them outstanding strength, hardness, and corrosion resistance while still allowing for good formability and weldability. After undergoing heat treatment, the material can achieve tensile strengths of up to 1310 MPa and yield strengths around 1170 MPa. It maintains its mechanical properties even at high temperatures, providing excellent fatigue and stress corrosion resistance in both annealed and hardened states.

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.
Sadiki Metals’ Stainless Steel 15-7 MO Bars and Rods are extensively utilized in industries that demand high strength, durability, and corrosion resistance in tough service conditions. In the aerospace sector, they are used to manufacture springs, fasteners, and structural components. The petrochemical and marine industries rely on them for shafts, valves, and fittings that need to endure harsh chemical and saltwater environments. Additionally, they find applications in power generation, chemical processing, and mechanical engineering, where high performance, dimensional stability, and long service life are crucial for critical equipment and precision parts.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
