Qhov sib txawv ntawm cov qauv hlau thiab 45 steel

Kev siv sib txawv thiab qhov zoo:
1. Cov qauv hlau yog cov khoom siv hauv tsev, feem ntau siv los ua cov qauv ntawm cov tsev, xws li kab teeb, kab, phab ntsa panels, thiab lwm yam. Nws qhov zoo yog weldability zoo, machinability thiab processability, nrog rau siab zog thiab zoo yas deformation muaj peev xwm. .
2. 45 steel muaj siab hardness, lub zog thiab hnav tsis kam, thiab yog siv dav hauv kev tsim khoom thiab cov cuab yeej txiav. Nyob rau tib lub sijhawm, 45 steel kuj muaj kev ua tau zoo dua thiab weldability.
