Stainless Steel 253 MA Bolts contain iron, 20–22% chromium, 10–12% nickel, with silicon, nitrogen, and cerium. These components increase the resistance of the alloy against oxidation, creep, and thermal fatigue, especially at high temperatures. The bolts exhibit high tensile strength, good toughness, and mechanical stability at high thermal loads. Withstand integrity at temperatures up to 1150°C in oxidizing atmospheres, their special composition and microstructure render them applicable in environments where scaling resistance, high-temperature strength, and long service life are paramount.
Stainless Steel 253 MA Bolts are specifically suited for applications demanding fastening solutions that are reliable in terms of high-temperature and oxidizing conditions. These bolts are widely utilized in the petrochemical sector, power plants, and thermal processing systems, more specifically in furnace parts, boiler parts, heat exchangers, and combustion chambers. They are suitable due to their resistance to thermal shock, scaling, and creep deformation for kilns, steel production, waste incinerators, and industrial gas turbines. Withstanding temperatures up to 1150°C, these bolts provide long-term stability in structure, thus being the first choice for engineers working on high-temperature fastening for long-lasting and effective solutions.
