When your project operates in extreme heat and pressure conditions, choosing the correct flange material is critical for safety and long-term performance. 310H Stainless Steel Flanges are specially engineered for elevated temperature applications where strength, oxidation resistance, and durability are essential.
We manufacture and supply a complete range of 310H Stainless Steel Flanges for industries such as oil & gas, petrochemical plants, power generation, heat treatment units, and chemical processing facilities. With practical industry experience and strict quality control procedures, we ensure every flange meets international standards and real-world operating demands.
What Are 310H Stainless Steel Flanges?
Stainless Steel 310H Pipe Flanges are produced from high-carbon austenitic stainless steel grade 310H. The higher carbon content (compared to standard 310) improves creep strength and mechanical stability at high temperatures.
Also known as Stainless Steel UNS S31009 Flanges, this material provides:
- Excellent oxidation resistance up to 1100°C (intermittent service)
- Strong resistance to scaling
- Good corrosion resistance in high-temperature environments
- Reliable mechanical strength under pressure
These flanges are widely used in furnace components, boilers, heat exchangers, and high-temperature piping systems
