310 Stainless Steel because of its high content of chromium and nickel medium, resistance to oxidation corrosion at the minor cycle condition of up to 2000 ° F.310 has good resistance to heat and other forms of corrosion of sulfide corrosion and widely applied in the medium in the carburizing atmosphere.
such as petrochemical environment, such as more demanding industrial heat treatment furnace carburizing atmosphere needs to choose RA330 ® or RA333 ®.It is not recommended to use 310 in the thermal shock corrosion condition of the intense circulating liquid quenching.

310 can provide different products form, its grain size and carbon content meet the 310 s and 310 h specification requirements, the strength of the excellent low temperature - 450 ° F, and low permeability, often used in low temperature environment, according to the evaluation of AISI B1112 machining performance of 42%.When using a high speed steel tool, process it at 70 feet/min. It is recommended to process it at room temperature and use AWS e310-15 electrode or ER310 welding wire.
