310S Stainless Steel Plate
310S Stainless Steel Plate is a high-performance, heat-resistant alloy known for its superior corrosion resistance and strength at elevated temperatures. It is commonly used in demanding industries such as aerospace, chemical, and heat exchangers. Made from a combination of chromium and nickel, 310S Stainless Steel Plate offers excellent resistance to oxidation, making it an ideal choice for high-temperature environments.
- Product Introduction
310S stainless steel plates aren't just heat-resistant-they're engineered to thrive in infernos. With 25% chromium and 20% nickel, this ultra-austenitic alloy laughs off oxidation at 1.150°C (continuous) and shrugs off thermal shocks that warp lesser steels. Designed for applications where molten salts, sulfur-rich gases, or cyclic heating push materials to their limits-think ethylene cracker tubes, cement rotary kilns, or nuclear reactor internals-it's the unyielding barrier between industrial chaos and operational continuity.
Why 310S Outclasses Competitors
| Challenge | 310S Plate | 309 | Inconel 601 |
|---|---|---|---|
| Max Continuous Heat | 1.150°C | 1.000°C | 1.200°C |
| Cost per Ton | $8.200 | $6.500 | $34.000 |
| Cyclic Oxidation (1.000 cycles) | 0.02 mm scale loss | 0.5 mm scale loss | 0.01 mm scale loss |
Key Properties
Cr/Ni Synergy: 25% Cr forms tenacious oxide layers; 20% Ni stabilizes structure against embrittlement.
Carbon Control: 0.08% max prevents carbide precipitation during prolonged heat exposure.
Sulfur Resistance: Withstands 5% H₂S environments up to 600°C (NACE MR0175 compliant).
