Qhov sib txawv ntawm Cov Hlau Kub Dov thiab Cov Hlau Txias Dov

1. Cov Qib Khoom Siv Hlau Kub Kub yog dab tsi?
Hlau yog ib hom hlau sib xyaw uas muaj cov pa roj carbon me me. Cov khoom hlau muaj ntau qib sib txawv raws li feem pua ​​ntawm cov pa roj carbon uas lawv muaj. Cov chav kawm hlau sib txawv raug muab faib ua pawg raws li lawv cov pa roj carbon. Cov qib hlau kub dov raug muab faib ua pawg carbon hauv qab no:
Cov hlau uas muaj cov pa roj carbon tsawg lossis cov hlau tsis hnyav muaj cov pa roj carbon tsawg dua 0.3%.
Cov hlau carbon nruab nrab muaj 0.3% txog 0.6% carbon.
Cov hlau uas muaj cov pa roj carbon ntau muaj ntau dua 0.6% carbon.
Cov khoom siv sib xyaw ua ke xws li chromium, manganese lossis tungsten kuj raug ntxiv me ntsis los tsim ntau qib hlau. Cov qib hlau sib txawv muab ntau yam khoom tshwj xeeb xws li lub zog tensile, ductility, malleability, durability, thiab thermal thiab electrical conductivity.

2. Qhov sib txawv ntawm Cov Hlau Kub Dov thiab Cov Hlau Txias Dov
Feem ntau cov khoom siv hlau yog tsim los ntawm ob txoj kev tseem ceeb: dov kub lossis dov txias. Cov hlau dov kub yog cov txheej txheem zeb uas cov hlau raug dov ntawm qhov kub siab. Feem ntau, qhov kub rau cov hlau dov kub tshaj 1700 ° F. Cov hlau dov txias yog cov txheej txheem uas cov hlau raug dov ntawm qhov kub thiab txias hauv chav tsev.
