Anucha Metals, a top-notch manufacturer and supplier located in Bangkok, Thailand, specializes in high-quality Stainless Steel 15-7 MO Bars and Rods that are designed to meet international performance and durability standards. With a strong background in precision manufacturing and a solid reputation for reliability, Anucha Metals guarantees that its 15-7 MO products cater to industries that demand exceptional strength and resistance to corrosion. This type of stainless steel is known for its precipitation-hardening properties, offering impressive strength, toughness, and resistance to both oxidation and corrosion. As a result, these bars and rods find extensive use in aerospace, chemical, petrochemical, and marine sectors for their demanding applications.
The composition of Stainless Steel 15-7 MO Bars and Rods primarily includes iron, along with 14–16% chromium, 6.50–7.75% nickel, and 2–3% molybdenum, plus carefully controlled amounts of aluminum, manganese, silicon, phosphorus, and sulfur. This alloy boasts a tensile strength of around 1170 MPa and a yield strength of up to 1035 MPa after heat treatment, all while maintaining good ductility. The molybdenum content significantly enhances resistance to pitting and crevice corrosion, while aluminum aids in precipitation hardening, resulting in superior mechanical properties in both annealed and heat-treated 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.
Stainless Steel 15-7 MO Bars and Rods are widely utilized in industries that require a blend of high strength, toughness, and corrosion resistance. In the aerospace sector, they are used for springs, diaphragms, and structural components that need to perform reliably under stress. The chemical and petrochemical industries incorporate them into reactors, heat exchangers, and piping systems that come into contact with corrosive chemicals. In marine applications, they serve as shafts, fasteners, and hardware that are exposed to seawater. Additionally, they are employed in the oil and gas and defense sectors for high-performance components. Thanks to their outstanding mechanical properties and durability, Stainless Steel 15-7 MO Bars and Rods are the go-to choice for critical engineering applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
