Cov pa roj carbon steel

Cov pa roj carbon steel yog cov hlau uas muaj cov ntsiab lus ntawm 0.05 txog 2.1 feem pua ​​​​ntawm qhov hnyav.

Cov hlau me me (hlau uas muaj feem pua ​​​​ntawm cov pa roj carbon tsawg, muaj zog thiab tawv tab sis tsis yooj yim tempered), tseem hu ua cov pa roj carbon steel thiab cov pa roj carbon tsawg, tam sim no yog cov hlau ntau tshaj plaws vim nws cov nqi qis thaum nws muab. cov khoom siv uas siv tau rau ntau daim ntawv thov. Cov hlau me me muaj kwv yees li 0.05-0.30% carbon. Cov hlau me me muaj lub zog tensile tsawg, tab sis nws yog pheej yig thiab yooj yim rau kev tsim; nto hardness tuaj yeem nce los ntawm carburizing.

Txuj No: GB / T 1591 Siab zog qis alloy cov qauv hlau
