We are Alloy 310H Plate and Processed Flat Bar provides superior resistance to corrosion and heat exposure, in even the most demanding environments.
- The high chromium content – intended to increase high temperature properties – also gives this grades good aqueous corrosion resistance.
- In high temperature service, 310H exhibits good resistance to oxidising and carburising atmospheres.
- 310H has good resistance to oxidation in intermittent service in air at temperatures up to 1040°C and 1150°C in continuous service.
- Good resistance to thermal fatigue and cyclic heating. Widely used where sulphur dioxide gas is encountered at elevated temperatures.
- Continuous use in 425-860°C range not recommended due to carbide precipitation, if subsequent aqueous corrosion resistance is needed, but it often performs well in temperatures fluctuating above and below this range.
- Prone to sigma phase embrittlement in the temperature range 650 – 900°C.
- Grade 310H is generally used at temperatures starting from about 800 or 900°C – above the temperatures at which 304H and 321 are effective
- Commonly used in the heat treatment and process industries due to high temperature and corrosive environments
- Often fabricated into complex structures
- Roller-forms, stamps and draws readily
- Because 310 work hardens, severe forming operations should be followed by an anneal
- Austenitic stainless steel is generally considered to be weldable
- Generally considered to have weldability equivalent to 304 and 304L
- Special consideration is needed to compensate for a higher coefficient of thermal expansion to avoid warping and distortion
