| titleOfInvention | A kind of raising austenitic stainless steel cryogenic gas carburizing speed urges infiltration method |
| abstract | A kind of raising austenitic stainless steel cryogenic gas carburizing speed of the present invention urges infiltration method, belong to chemical heat treatment technology field, the present invention is in 450 DEG C~470 DEG C, gas carburizing processing is carried out to austenitic stainless steel using mixing carburizer, the mixing carburizer is made up of Gas Carburizing agent and liquid phase rare-earth energizer, and the Gas Carburizing agent is by CO, H 2 And N 2 Composition；The liquid phase rare-earth energizer by rare earth chloride and methanol solution composition；Caused gas collectively forms carburizing furnace gas after the solvent methanol of the Gas Carburizing agent and liquid phase rare-earth energizer gasifies in carburizer, the mass fraction of the rare earth element of its liquid phase rare-earth energizer is the 0.8~1.5% of carburizer gas mass fraction, keep 24~48h of processing, it is cooled to less than 150 DEG C in former atmosphere furnace, the anti-corrosion reinforcing carburized layer that case hardness is 850HV~1200HV is obtained in austenitic stainless steel, the present invention improves the treatment effeciency of the anti-corrosion reinforcing of austenitic stainless steel, reduces production cost. |
