Steel siv:
Cov hlau tuaj yeem muab faib ua cov qauv hlau, cov cuab yeej hlau, cov hlau tshwj xeeb thiab cov hlau ua haujlwm raws li kev siv sib txawv.
Cov qauv hlau tau muab faib ntxiv rau hauv cov qauv hlau rau kev tsim kho thiab engineering thiab cov qauv hlau rau kev tsim cov tshuab. Cov qauv hlau rau kev tsim kho thiab kev tsim vaj tsev yog cov hlau siv los tsim cov khoom siv hlau hauv cov tsev, txuas hniav, boilers, lossis lwm yam dej num, feem ntau cov hlau tsis tshua muaj. Txij li feem ntau ntawm lawv yuav tsum tau welded, lawv cov ntsiab lus carbon yuav tsum tsis txhob siab dhau. Mechanical manufacturing structural steel yog siv los tsim cov txheej txheem ntawm cov cuab yeej siv tshuab, uas yog qhov pib siab - zoo steel thiab siab - qib siab - zoo steel.
