25%Cr-20%Ni stainless steel.SS310(S31000) is the common grade in standard of ASTM A167 only. The casting grade is named as CK20 (J94202)) in standard of ASTM A743/A743M. The high alloy content of SS310 give good high temperature properties with good ductility and weldability, mainly used for high temperature service, such as heat shields, furnace part and ducting.
The low carbon content is 310S/310H listed in standard of ASTM A240.
Grade 310L in ASTM A240 is a 0.03% max carbon grade of 310, used for special corrosive application.
Casting Quality Industrial provide CK20 (SS310) by sand casting or investment casting (lost wax precision casting) process.
