1: 4140 steel kev taw qhia
AISI SAE 4140 alloy steel yog chromium molybdenum alloy steel specification dav siv dav hauv lub hom phiaj siab tensile steel rau cov khoom, xws li axles, shafts, bolts, zog thiab lwm yam kev siv. Zoo ib yam li alloy qib AISI 4130 chrome moly alloy steel tab sis nrog cov ntsiab lus siab dua me ntsis. Cov ntsiab lus carbon ntau dua ntawm AISI 4140 steel muab lub zog ntau dua thiab kev kho cua sov muaj peev xwm sib piv rau AISI / ASTM 4130 alloy steels, txawm li cas los xij nws muaj cov yam ntxwv tsis zoo weldability.
