Alloy 4140 (AISI 4140) yog ib qho nrov tshaj plaws ncaj qha hardening Cr-Mo alloy steel daim hlau uas muaj peev xwm tsim tau ntau yam hardness thiab lub zog. Alloying ntsiab lus thiab thermal kho, xws li quenching thiab tempering, zoo heev cuam tshuam lub hardness thiab lub zog ntawm cov hlau.
Alloy 4140 phaj yog dav siv rau cov hom phiaj kev lag luam. Vuam thiab tsim ntawm no steel phaj yuav tsum zam. Nws yog qhov zoo tshaj plaws siv nyob qhov twg muaj zog tiv thaiv qaug zog thiab los yog cuam tshuam yog tsim nyog.
