1. Dab tsi yog carbon steel seamless yeeb nkab?
Teb: Cov pa roj carbon steel seamless yeeb nkab yog cov yeeb nkab uas tsis muaj vuam seam, ua los ntawm carbon steel billet los ntawm kub dov, txias kos duab los yog extrusion txheej txheem. Nws muaj qhov zoo ntawm kev kub siab ua haujlwm, zoo toughness thiab uniform qauv.
2. Dab tsi yog cov qib ntawm cov pa roj carbon zoo tib yam seamless kav?
Teb: Cov qib zoo sib xws yog 10 # thiab 20 # carbon steel. Lawv yog cov hlau tsis muaj cov pa roj carbon tsawg, nrog cov ntsiab lus carbon tsawg (0.10% -0.23%), zoo plasticity thiab weldability, thiab tau dav siv hauv kev lag luam dav dav.
3. Dab tsi yog cov qib siab - specifications ntawm carbon steel seamless kav thiab lawv cov yam ntxwv?
Teb: Feem ntau cov qib siab- cov lus qhia tshwj xeeb suav nrog 45 # (cov pa roj carbon nruab nrab) thiab 16Mn (tsawg alloy siab- zog carbon steel). 45# muaj cov ntsiab lus carbon siab (0.42%-0.50%), siab zog thiab hardness tab sis tsis zoo weldability; 16Mn muaj ib qho me me ntawm manganese, uas txhim kho lub zog thiab tawv, thiab muaj kev ua haujlwm zoo dua li cov pa roj carbon zoo tib yam.
Dab tsi yog cov ntsiab lus ntawm 10 # carbon steel seamless yeeb nkab?
Teb: Cov ntsiab lus carbon ntawm 10 # carbon steel seamless yeeb nkab yog 0.07% -0.14% (qhov loj feem), uas yog ib qho qis carbon steel.
5. Dab tsi yog qhov txawv ntawm txhua yam khoom ntawm 20 # thiab 45 # carbon steel seamless kav?
Teb: 20 # carbon steel muaj lub zog tensile ntawm 345-490MPa, yield zog ntau dua los yog sib npaug rau 245MPa, thiab zoo plasticity thiab toughness; 45 # carbon steel muaj lub zog tensile ntawm 600MPa, yield zog ntau dua los yog sib npaug rau 355MPa, siab zog thiab hardness, tab sis qis plasticity tshaj 20 #.
