S420nl phaj yog lub hmoov nplej zoo qauv hlau, uas yog lub zog siab steel phaj nyob hauv European tus qauv en 10025.
S420nl steel phajMuaj cov khoom siv kho dua hauv qab qhov xwm txheej ntawm kev coj ua lossis ib txwm ntxiv rau kev ua kom tempering.
Cov khoom siv thiab cov ntsiab lus ntawm s s420NL zoo ib yam li Q420e qib hauv Suav teb.
Dab tsi yog qhov sib txawv ntawmS420n daim hlauThiab S420NL Hlau Phaj
S420 steel phaj yuav tsum tau faib ua almoy tshwj xeeb steel. S420 steel yog muab rau hauv cov qib hauv qab no: Thaum qhov kub tsis qis dua {}} degree, qhov tsawg kawg nkaus tus nqi yog qhia los ntawm n, uas yog s420n. Thaum qhov kub tsis qis dua - 50 degree, qhov tsawg kawg nkaus cuam tshuam lub zog yog qhia los ntawm NL, uas yog s420NL.
