X6CrNiTi18-10

HuaNickel X6CrNiTi18-10 stainless steel is a titanium stable grade that is typically used in the 1000-1600°F temperature range. For operating temperatures up to 1600°F, a stable treatment of 1550-1650°F, air cooling, can be used to provide optimal resistance to intergranular corrosion and polysulfuric acid stress corrosion cracking. X6CrNiTi18-10 stainless steel is easily welded by all common methods, including water arcing. The appropriate weld fillers are AWS ER347 bare wire and E347 overlay electrodes. The machinability of HuaNickel X6CrNiTi18-10 stainless steel is similar to that of 304 stainless steel. Compared to AISI B1112, it has a machinability rate of 45%.
