Chemical Composition  and mechanical properties

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.
