Cov Hlau Carbon Siab Cov Phaj ASTM A36 Cov Hlau Kub Dov Carbon 0.2mm 30-275g S275jr 0.5mm 1mm Cov Hlau Carbon Tsawg Me Me
Cov hom hlau carbon yog dab tsi?
1. Cov hlau ua los ntawm cov pa roj carbon:
Kev siv tseem ceeb: txhua yam kev tsim kho. Feem ntau muab los ntawm cua txias tom qab dov kub, Cov neeg siv feem ntau tsis tas yuav kho cua sov thiab siv ncaj qha. Muaj tsib qib ntawm cov hlau no raws li lawv lub zog tso zis. Cov cim qib: A, B, C, D (Qib D ncav cuag qib ntawm cov hlau zoo)
2. Cov hlau ua los ntawm cov pa roj carbon zoo:
Kev siv tseem ceeb: cov khoom tseem ceeb. Cov khoom siv kho tshuab ntawm cov khoom tuaj yeem hloov kho los ntawm kev kho cua sov Cov hom lag luam feem ntau siv: 08F, 10 #, 15 #, 20 #, 35 #, 45 #, 60 #, thiab lwm yam
3. Cov hlau siv ua cov cuab yeej carbon (WC=0.65%~1.35% yog cov hlau carbon siab):
Kev siv tseem ceeb: ua ntau yam cuab yeej me me. Kev nyuaj siab thiab kev hnav tsis kam tuaj yeem tau los ntawm kev quenching thiab tempering kub tsawg. Nws muab faib ua ob pawg ntawm qhov zoo thiab qhov zoo.
4. Kev tsim kho dav dav hlau cam khwb cia hlau (cam khwb hlau):
Kev siv tseem ceeb: nyuaj rau tsim los ntawm kev forging thiab nias thiab lwm txoj hauv kev ntawm cov khoom nyuaj thiab cov khoom siv kho tshuab siab;
