Based in Amman, Jordan, Sabra Metals is a trusted manufacturer and supplier of top-notch Stainless Steel 253MA Hex Bars, designed for high-temperature and oxidation-resistant applications. Crafted from nitrogen-enhanced, high-chromium austenitic stainless steel, these hex bars provide remarkable strength and stability even in extreme thermal conditions. Sabra Metals takes pride in maintaining strict standards for chemical composition, dimensional accuracy, and surface finish to comply with international benchmarks. With state-of-the-art manufacturing facilities and reliable supply capabilities, the company caters to industries like furnace manufacturing, petrochemical, power generation, and heavy engineering around the globe.
Stainless Steel 253MA Hex Bars are composed of chromium (20–22%), nickel (10–12%), nitrogen, and rare earth elements, all of which boost oxidation resistance and high-temperature strength. This unique blend ensures excellent protection against scaling, carburization, and thermal fatigue, even at temperatures reaching around 1150°C. On the mechanical side, SS 253MA boasts impressive tensile strength, outstanding creep resistance, and high toughness at elevated temperatures. It retains stable mechanical properties, even after prolonged exposure to heat and thermal cycling.

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 their place in a variety of applications that face extreme heat and harsh environments. Common uses include high-temperature fasteners, furnace hardware, burner components, radiant tube supports, and heat treatment equipment. They are heavily utilized in power generation plants, petrochemical processing facilities, steel manufacturing, and industrial heating systems. Additionally, SS 253MA hex bars are ideal for structural and fabricated components that operate in high-temperature zones, where oxidation resistance, mechanical reliability, and a long service life are essential.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
