Type 310310S is an austenitic heat resisting alloy with an excellent resistance to oxidation unde4r mildly cyclic conditions to 2000#F. Rapid thermal cycling increase the rate of metal wastage somewhat by spalling of the protective oxide scale. The oxidation resistance of A1.310 is significantly better than that of A1.309.
The chromium content of A1.310 provides resistance to Aqueous corrosion under oxidizing conditions. A1.310 is susceptible to chloride ion stress corrosion cracking but is superior in this respect to the lower alloy stainless 304 and 316 A1.310 has fair resistance to polythionic acid attack. Resistance to intergranular attack of material intended for service in the 850 to 1000#F range may be improved by thermal stabilization at 1550-1650F for four hours.
Application :
A1.31o is widely used in moderately carburising atmosphere such as encountered in petrochemical environments.
Corrosion Resistance :
This grade posses excellent corrosion resistance and withstands scaling at temperatures up to 2000+F. Its corrosion resistance ereaches maximum in the annealed condition.
