The Stainless Steel 253Ma Hex Bar is mainly made up of iron, nickel, chromium, nitrogen, and small amounts of rare earth metals that boost its oxidation resistance and strength at high temperatures. With a composition of 20–22% chromium and 10–12% nickel, it provides remarkable corrosion resistance and can withstand scaling up to 1150°C. In terms of mechanical properties, it delivers high tensile and yield strength, good toughness, and excellent creep resistance. This impressive combination of mechanical attributes and oxidation resistance makes it ideal for high-stress applications that demand durability in extreme thermal conditions.

The pressure rating of Stainless Steel 253Ma Hex Bar depends on the specific application and design parameters, such as temperature and load conditions. It is primarily used for high-temperature applications, with its pressure rating varying based on engineering requirements and specifications.
To choose the right Stainless Steel 253Ma Hex Rods, consider factors like temperature resistance, corrosion exposure, and mechanical strength required for your application. Consult with suppliers or engineers to ensure compatibility with the operating environment and design specifications.
Stainless Steel 253Ma Hex Bar generally offers excellent corrosion resistance due to its high chromium content, reducing the need for additional coatings. However, in highly aggressive environments, extra protective coatings may be beneficial for enhanced longevity.
Stainless Steel 253Ma Hex Bars find extensive use in industries that require exceptional heat and corrosion resistance. Their capability to perform in extreme temperature environments makes them perfect for applications in furnaces, kilns, power plants, and the petrochemical sector. They are commonly used in the production of furnace components, heat exchangers, boilers, burners, and conveyor systems. Additionally, these bars are highly valued in the cement, metallurgical, and chemical industries, where scaling resistance and longevity are essential. Their strength, durability, and versatility make them the go-to choice for critical high-temperature 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.
