1: 1.2767 steel kev taw qhia
1.2767 yog cov roj carbon ntau dua ntawm tus qauv 4.25 feem pua nickel roj hardening hlau. Nws yog cov cuab yeej zoo hlau uas ua tiav cov kev cuam tshuam siab thiab lub zog compressive thiab tsim nyog rau cov ntawv thov xav tau ntxiv hnav tsis kam. Nrog nws cov yam ntxwv ntawm zoo tag nrho hardenability, zoo polishability thiab zoo heev toughness no txias ua hauj lwm cuab tam steel specification yog dav siv rau yas pwm daim ntaub ntawv.
