Grade 310, combining excellent high temperature properties with good ductility and weldability, is designed for high temperature service. It resists oxidation in continuous service at temperatures up to 1150 Degree C provided reducing sulphur gases are not present. It is also used for intermittent service at temperatures up to 1040 Degree C.Like other austenitic grades these have excellent toughness, even down to cryogenic temperatures, although other grades are normally used in this environment.
