2. Comparison of application fields of stainless steel 310H valve (UNS S31009 valve) and stainless steel 310S valve (UNS S31008 valve)

Typical application scenarios of stainless steel 310H valve (UNS S31009 valve) is high-temperature pressure-bearing parts, such as:

① Petrochemical industry: cracking furnace tubes, converter parts (need to withstand high temperature + stress).

② Power industry: boiler burners, superheater tubes (operating temperature can reach 1100°C).

③ Heat treatment equipment: high-temperature furnace rollers, muffle tanks (need to resist creep).

So the key requirement for selecting stainless steel 310H valve should be: maintaining structural strength in long-term high temperature environments (such as >800°C).

② Chemical containers: corrosive medium storage tanks (low carbon reduces the risk of intergranular corrosion).

③ General heat-resistant parts: heat exchanger pipes, flue linings (temperature ≤1000°C).

Therefore, the key requirements for selecting stainless steel 310S valve should be: corrosion resistance, easy molding or welding, and low high-temperature stress scenarios.
