Dab tsi yog qhov ntsuas kub rau SA 387 GR 11 CL 2?
Nyob rau hauv qis kawg ntawm qhov kub thiab txias ntawm qhov ntsuas kub thiab 1150℃f Min tempering kub), thiab sa 387 gr 22 (1250℃f Min tempering kub) yog siv. Cov qhab nia no tuaj yeem sau cov chav kawm 1 lossis 2 thiab tseem tuaj yeem muab rau hauv qhov qub & tempered lossis quenched thiab npau taws.
Dab tsi yog lub hardness ntawm sa 387 Gr 22 chav kawm2?
Hardness Xav Tau:
Brinell Hardness (HBW): tsawg dua lossis sib npaug ntawm 220 HBW (cov qauv yuav tsum tau tom qab ib txwm + Tempering).
Cov NTAU: 180-210 HBW (kev ntsuas ntsuas qhov tseem ceeb tom qab kev kho cua sov).
