Dawb txiav hlau yog hais txog cov hlau alloy uas ntxiv qee qhov ntawm ib lossis ntau qhov dawb txiav cov ntsiab lus xws li sulfur, phosphorus, txhuas, calcium, selenium, tellurium, thiab lwm yam los txhim kho nws cov machinability.Nrog rau automation, high-speed thiab precision ntawm txiav, nws yog ib qho tseem ceeb heev uas yuav tsum tau steel kom muaj zoo machinability, uas yog tsuas yog siv rau kev ua nyob rau hauv tsis siv neeg txiav machine.Cov hauv qab no tsom rau qhov sib txawv ntawm 1215 dawb txiav hlau thiab 11SMn30 dawb txiav hlau.
1215 yog ib hom kev yooj yim txiav hlau hauv American ASTM / AISIBI tus qauv series.1215 dawb txiav hlau yog cov khoom siv zoo ib puag ncig uas tsis muaj cov hmoov txhuas lossis cov khoom tsis zoo rau ib puag ncig.Nws muaj cov cuab yeej txiav zoo thiab tsim nyog rau cov khoom siv hluav taws xob dav dav, cov ntaub ntawv txiav, thiab cov khoom siv dav dav.
