AISI 4140 Steel Bar, Steel Phaj, Flats Supplier, Stockist thiab Exporter. AISI SAE 4140 alloy steel yog chromium molybdenum alloy steel specification dav siv nyob rau hauv dav dav lub hom phiaj siab tensile steel rau Cheebtsam, xws li axles, shafts, bolts, zog thiab lwm yam kev siv. Zoo ib yam li alloy qib AISI 4130 chrome moly alloy hlau tab sis nrog cov ntsiab lus carbon ntau 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.
