310S Stainless Steel Coil Hot Rolled No.1 Heat Resistant 0.8mm-3.0mm 1500mm Width for Boiler Furnace Equipment
310S Stainless Steel Coil - Heat Resistant Grade No.1 Finish
Our 310S stainless steel coil is a high-alloy austenitic stainless steel with 25% chromium and 20% nickel, specifically engineered for elevated temperature service. It maintains structural integrity and outstanding oxidation resistance under continuous operation up to 1100°C in oxidizing atmospheres. The No.1 hot rolled finish is ideal for heavy industrial fabrication where surface aesthetics are secondary to thermal performance. This product is highly sought after in Middle Eastern oil & gas, European industrial manufacturing, and Southeast Asian processing industries.
Key Features
- Exceptional High Temperature Performance: Maintains strength and oxidation resistance at continuous service temperatures up to 1100°C
- Superior Oxidation Resistance: High chromium (24-26%) and nickel (19-22%) content forms a stable protective oxide layer at elevated temperatures
- Low Carbon Variant: 310S (max 0.08% C) prevents embrittlement and sensitization from carbide precipitation during high-temperature service
- Good Hot Strength: Retains mechanical properties at temperatures where standard 304/316 grades would fail
- Resistance to Thermal Cycling: Excellent performance under repeated heating and cooling cycles without cracking
