When your project involves extreme heat, standard stainless steel just won’t cut it. SS 310S Plates are premium austenitic stainless steel plates designed for high-temperature and high-performance industrial applications. Known for their exceptional oxidation resistance and excellent mechanical strength, SS 310S is widely used in environments where elevated temperatures and corrosive conditions are common.
Quality SS 310S Plates begin as semi-finished slabs. These slabs are meticulously rolled into flat products, undergoing hot-rolling or cold-forming to reach the precise thickness and surface finish required for your specific engineering needs. If your industry demands durability, reliability, and long service life under extreme heat, SS 310S Plates are the ideal material choice.
Key performance benefits:
- Oxidation Resistance: SS 310S Plates provide fantastic protection against oxidation under mildly cyclic conditions at temperatures up to 2000°F.
- Cryogenic Toughness: Unlike many heat-resistant alloys, 310S maintains excellent durability even at cryogenic temperatures as low as –450°F.
- Magnetic Properties: These plates feature low magnetic permeability, making them ideal for specialized electronic or sensitive industrial applications.
- High-Temperature Strength: By incorporating solid carbide formers like tungsten, molybdenum, vanadium, and chromium, the alloy retains a larger fraction of its room-temperature strength even when glowing red.
