These Stainless Steel 310/310S Fasteners are made up of 24–26% chromium and 19–22% nickel, which give them outstanding oxidation resistance, even at temperatures reaching 1100°C during continuous service. The 310S grade features a maximum carbon content of 0.08%, which not only boosts weldability but also helps to minimize intergranular corrosion. With a high tensile strength of around 520 MPa, along with excellent ductility and toughness—even in cryogenic conditions—these fasteners are perfect for high-temperature structural applications.
You’ll find Stainless Steel 310/310S Fasteners widely used in situations where there’s constant exposure to high heat and thermal cycling. They’re ideal for furnace components, heat exchangers, radiant tubes, and combustion chambers in thermal processing industries. In the petrochemical field, they’re utilized in reformers and reactors. Plus, they hold up well in marine and coastal environments thanks to their corrosion resistance in saltwater. With their impressive combination of high-temperature strength, corrosion resistance, and metallurgical stability, SS 310/310S Fasteners are a reliable choice for even the most extreme service conditions.
