These bolts are primarily made up of chromium (24–26%) and nickel (19–22%), with a touch of carbon that boosts their strength when the heat is cranked up. They boast impressive tensile strength ranging from 515 to 690 MPa and a yield strength of about 205 MPa, along with excellent creep resistance and thermal stability. Their mechanical properties hold strong even in extreme heat, and their unique composition helps them resist oxidation, scaling, and thermal fatigue. This makes SS 314 Bolts a solid choice for long-term use in high-temperature settings.

You’ll find Stainless Steel 314 Bolts in action across industrial furnaces, heat exchangers, boiler assemblies, and thermal processing units. They’re also commonly used in power plants, chemical processing equipment, and petrochemical facilities, where components face high temperatures and corrosive conditions. Their ability to maintain strength, resist scaling, and keep their structural integrity under thermal stress makes them an ideal pick for securing equipment and structural assemblies in demanding high-temperature applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
