Kev kho cua sov specification thiab metallographic qauv:
Kev kho cua sov specification: normalizing, 870 ℃; quenching, 850 ℃; tempering, 600 ℃.
Metallographic qauv: ferrite + pearlite.
Kev xa khoom: xa hauv lub xeev yam tsis muaj kev kho cua sov lossis kev kho cua sov (annealing, normalizing lossis kub tempering). Yog hais tias tus me nyuam yuav tsum tau muab xa mus rau hauv kev kho cua sov, nws yuav tsum tau teev nyob rau hauv daim ntawv cog lus, thiab yog hais tias nws tsis tau teev, tus me nyuam yuav tsum tau muab xa mus tsis muaj kev kho cua sov.
