12L14 Dawb-Txiav Hlau Bar

A steel nrog ib tug ntau dua li ib txwm cov ntsiab lus ntawm cov leej faj thiab phosphorus npaj rau ntawm cov khoom siv rau qhov chaw kom nrawm nrawm thiab cov cuab yeej Semiautomatic tshuab. Dawb-txiav hlau yog tsim nyob rau hauv daim ntawv ntawm cov pas nrig, thiab nws muaj 0.08-0.45 feem pua ​​carbon, 0.15-0.35 feem pua ​​silicon, 0.6-1.55 feem pua ​​manganese, 0.08-0.30 feem pua ​​ntawm leej faj, thiab 0.05-0.16 feem pua ​​phosphorus. Cov neeg Sulfur cov lus tseem ceeb ua rau muaj kev tsim ntawm kev suav nrog (piv txwv li, Manganese sulfide) muab pov tseg raws cov nplej. Cov interrusions pab txhawb kev sib tsoo thiab txhawb kev sib tsoo thiab nti yooj yim. Rau cov hom phiaj no, cov hlau tso nyiaj pub dawb yog txuam nrog cov hmoov txhuas thiab qhia.

12L14 yog hom kev tswj hwm thiab rov ua dua cov roj carbon hlau rau kev siv dawb-txiav thiab kev siv machining. Tus txheej txheem hlau (cov hlau tsis siv neeg) muaj lub zog zoo heev thiab qis dua lub zog zoo li cov neeg tuaj yeem txo qhov ua tiav thiab precision ntawm kev machined seem. 12L14 Hlau tau siv dav nyob rau hauv kev tsim cov khoom siv thev naus laus zis, cov khoom lag luam uas yog suav nrog ntau yam ntawm cov tshuab, cov ntaub ntawv, ntxeem, fittings, fittings thiab lwm yam.
