Product description

Great ductility, weldability, and high-temperature properties make 310 stainless steel tube the ideal choice for projects that require service at temperatures up to 1150 degrees Celsius. Grade 310 resists oxidation and is also used at temperatures up to 1040 degrees Celsius intermittently. Similar to other austenitic steel grades, toughness down to cryogenic temperatures is another feature of 310 stainless steel tube.

 

Excellent resistance to oxidation under mildly cyclic conditions through 2000°F characterizes 310 stainless steel tube. Because of its high chromium and medium nickel contents, 310 stainless steel tube has good resistance to sulfidation and other forms of hot corrosion. 310 stainless steel is widely used in moderately carburizing atmospheres such as encountered in petrochemical environments. The more severely carburizing atmospheres of industrial heat treating furnaces require RA330® or RA333®. 310 stainless steel is not suggested for the severe thermal shock of repeated liquid quenching.

                                                               

Often in many product forms, the grain size and carbon content can meet both the 310S and 310H requirements. 310 is often used at cryogenic temperatures, with excellent toughness to -450°F, and low magnetic permeability. 310 has a machinability rating of 42% relative to AISI B1112 steel. When using high speed steel tooling, this equates to about 70 surface feet per minute. Forming operations should be performed at room temperature whenever possible. Welding with AWS E310-15 electrodes or ER310 bare wire is suggested.
