The austenitic stainless steel 310S (UNS S31008/AISI310S) has about 25% Cr, 0, 6 % Si and 20% Ni. This grade is known for its behavior of corrosion resistance at high temperature. The additions of carbon are optimized in order to improve its creep deformation resistance. The steel can easily be welded. AISI 310S is projected for high temperature applications, up to 1100°C, in oxidating atmospheres.

310S stainless steel chemical composition %:

C(max):0.08, Mn(max):2.00, P(max):0.045, S(max):0.030, Si(max):1.50, Cr:24.0-26.0, Ni:19.0-22.0

310S stainless steel mechanical properties:

Tensile strength(min):515Mpa, Yield strength(min):205Mpa, Elongation in 2 in. or 50 mm, min, %: 40, Hardness: HB(max): 217, HRB(max):95

310S stainless steel application:

Grade AISI 310S is mainly used at high temperature due to its corrosion resistance. The typical working temperatures for an atmosphere with maximum Sulfur content of 2g/m3 are 1050℃ (continuous service) and 1100℃ (peak temperature). Sulfur contents higher than 2g/m3 decrease maximum temperature to 950℃.

After a long period of exposure to high temperature, grade 310S can be susceptible to intergranular corrosion due to precipitation of chromium carbides. Anyway, this grade is resistant to electrochemical corrosion due to its high content of chromium and nickel.

310S stainless steel welding:

Grade 310S can be welded using the majority of welding processes: TIG, MIG, plasma, submerged arc, coated electrode and tubular wire. The electrodes AWS/ASME E310-15 or wires AWS/ASME ER 310 are commonly used. For the welding of the finishing pass, the use of AWS/ASME E309-15 or wires AWS/ASME ER 309 is recommended. If the fluidity of the weld pool is a problem, the use of filler metals with silicon (ER309LSi or ER309Si) are recommended.

The mechanical properties of the welded joints are improved for processes of submerged arc welding using basic flow and for processes with argon shielding gas.
