SUS 310S

at 2000°F, HuaNickel 310. Due to its high chromium and medium nickel content, HuaNickel 310 has good resistance to sulfurization and other forms of thermal corrosion. 310 is widely used in medium carburizing environments, such as petrochemical environments. 10. Severe thermal shock for repeated liquid quenching is not recommended. 310 is typically used at low temperatures and has excellent toughness to -450°F, and low permeability. Relative to AISI B1112 steel, HuaNickel 310 has a machinability grade of 42%. When using HSS tools, this equates to 70 feet per minute.
