310 stainless steel is an austenitic stainless steel developed for use in high temperature corrosion resistant applications. Typically used in coal combustors, radiator tubes, steam boilers, thermowells, burners, combustion chambers, food processing equipment, and cryogenic hardware. 310S is the low carbon version of the stainless steel. It is utilized for ease of fabrication.
Corrosion Resistance: 310/310S stainless steel has excellent corrosion resistance in a wide range of environments. It can withstand exposure to water, chemicals, and other corrosive substances without corroding or rusting.
Strength: 310/310S stainless steel has high tensile strength and can withstand heavy loads without bending or breaking. It has a minimum tensile strength of 515 MPa and a minimum yield strength of 205 MPa.
Ductility: 310/310S stainless steel has good ductility, which means that it can be easily formed and shaped without cracking or breaking. This property makes it ideal for applications that require complex shapes or designs.
Weldability: 310/310S stainless steel is easily weldable, making it an excellent choice for applications that require welding. It can be welded using common welding techniques, such as TIG, MIG, and resistance welding.
Magnetic Properties: 310/310S stainless steel is non-magnetic, which makes it suitable for applications that require non-magnetic properties.
Heat Resistance: 310/310S stainless steel has excellent heat resistance and can withstand high temperatures without losing its strength or corrosion resistance. It can withstand temperatures up to 1150°C (2100°F) without undergoing any significant change in its properties.

Machinability Grades 310/310S stainless steel are similar in machinability to type 304. Work hardening can be a problem and it is normal to remove the work hardened layer by using slow speeds and heavy cuts, with sharp tools and good lubrication. Powerful machines and heavy, rigid tools are used.
Welding Grades 310/310S are welded with matching electrodes and ﬁller metals. The alloys are readily welded by SMAW (manual), GMAW (MIG), GTAW (TIG) and SAW. Electrodes to AWS A5.4 E310-XX and A 5.22 E310T-X, and ﬁller metal AWS A5.9 ER310 are used. Argon is shielding gas. Preheat and post heat are not required, but for corrosion service in liquids full post weld solution annealing treatment is essential. Pickling and passivation of the surface to remove high temperature oxides are essential to restore full aqueous corrosion resistance after welding. This treatment is not required for high temperature service, but welding slag should be thoroughly removed.
