310 Stainless Steel for Heat Treatment Furnace Components

1. What furnace components are made of 310 stainless steel? Radiant tubes, muffle tanks, furnace rollers, and heat-resistant brackets.

2. How long does 310 last in a heat treatment furnace? It has a service life of several years under proper operating conditions (dry air, ≤1150°C).

3. Can 310 be used for vacuum furnace components? Yes, it performs well in vacuum high-temperature environments.

4. Why is 310 better than 309 for furnace parts? It has higher Cr-Ni content, offering superior oxidation resistance and high-temperature strength.

5. How to repair 310 furnace components? Weld repair using ER310 consumables followed by solution annealing to restore performance.
