Product description:
310S ia highly alloyed austenitic stainless steels designed for service at elevated temperature.The high Cr and Ni contents enable this alloy to resist oxidation in continuous service at temperatures up to 1200℃ provided reducing sulfur gases are not present.
These Grades are used for high-temperature oxidation resistance for applications.such as furnace parts,furnace conveyer belts,insulation holding studs,etc.
Corrosion Resistance:In many processes,isothermal (constant temperature) conditions are not maintained and process temperature vary.Expansion differences between the base metal and the scale during heating and cooling can cause cracking and flaking of the projective scale.
This allows the oxidizing media to attack the exposed metal surface.The repeated flaking will reduce the cross section and parts will fail.The spalling resistance is greatly improved with the higher nickel contents in these grades because nickel reduces the expansion differential between the scale and the base metal.
Annealing:Annealing is achieved by heating to between 1038℃ and 1120℃ for 60 minutes per inch thickness followed by water quenching.Annealing will ensure that any carbide preciptitates are takend back into solution.
Welding:310S can be satisfactorily welded and brazed by all methods,giving a tough weld.Welding procedures should be selected with care in order to avoid hot cracking due to the fully austenitic weld micristruce obtained from using matching filler metal.
