310S Grade Chemical Composition and Technical Property is as below：
Standard | C % max | Si max | Mn max | P max | S max | tensile strength（MPa） | yield strength（MPa） | Elongation% |
310S | 0.08 | 1 | 2 | 0.045 | 0.03 | ≥520 | ≥205 | ≥40 |
| Property | Advantage |
| High Chromium (24–26%) | Forms a stable, self-healing oxide scale that resists scaling and spalling at elevated temperatures |
| High Nickel (19–22%) | Maintains austenitic structure and toughness; resists embrittlement during thermal cycling |
| Low Carbon (≤0.08%) | Minimizes carbide precipitation and intergranular corrosion in the 425–860°C sensitization range |
| Excellent Creep Resistance | Retains load-bearing capacity during long-term exposure to high stress and temperature |
| Good Weldability | Can be welded using standard austenitic filler metals; post-weld heat treatment generally not required |
Q: Can 310S parts be used above 1000°C?
A: Yes. 310S is rated for continuous service up to 1150°C and intermittent exposure to 1035°C. Its high chromium and nickel content form a protective oxide scale that resists further oxidation. For temperatures exceeding 1150°C or highly reducing sulfur-rich environments, higher-nickel alloys such as 330 or Inconel may be required.
Q: Does laser cutting affect the high-temperature properties of 310S?
A: When cut with proper parameters—nitrogen assist gas, controlled power, and optimized speed—the heat-affected zone (HAZ) is minimal and does not significantly alter the alloy's high-temperature performance. We avoid excessive heat input that could cause localized grain growth or sensitization.
Q: Can you supply 310S parts with welded or formed features?
A: Yes. We provide CNC press brake bending, TIG welding with 310S filler metal, and hardware insertion. Formed and welded 310S assemblies are common for furnace baskets, ducting sections, and burner housings. Welding is typically followed by pickling to restore corrosion resistance.
Q: What is the typical lead time for custom 310S laser-cut parts?
A: Prototype orders typically ship within 5–8 business days after drawing approval. Bulk production runs range from 10 to 25 days depending on thickness, quantity, and secondary processing requirements. 310S is a specialty alloy, so material availability for non-stocked thicknesses may add 1–2 weeks.
