1.Vim li cas 45 # carbon steel seamless yeeb nkab tsis haum rau vuam?
Teb: 45 # carbon steel muaj cov ntsiab lus carbon siab. Thaum lub sij hawm welding, lub tshav kub - cuam tshuam cheeb tsam yog nquag mus hardening thiab cracking, thiab weld toughness yog txo. Yog xav tau vuam, preheating (150-250 degree) thiab tom qab vuam cua sov yog xav tau, uas ua rau kom cov txheej txheem complexity.
2. Dab tsi yog daim ntawv thov ntawm 10 # carbon steel seamless yeeb nkab?
Teb: Nws yog tsuas yog siv nyob rau hauv qis - kev thauj mus los ntawm cov dej siab (xws li dej, roj, roj), thiab tseem siv rau hauv kev tsim cov khoom siv uas tsis muaj zog, xws li brackets, tes tsho, thiab lwm yam.
3. Lub sijhawm twg yog 16Mn carbon steel seamless kav dej haum rau?
Teb: 16Mn muaj lub zog siab thiab zoo toughness, thiab yog haum rau nruab nrab thiab siab siab kev thauj mus los (xws li roj thiab roj pipelines), mechanical structural parts, thiab engineering tej yaam num (xws li txuas hniav, vaj tse) uas yuav tsum tau siab load- bearing muaj peev xwm.
4. Qhov siab tshaj plaws ua haujlwm siab ntawm 20 # carbon steel seamless yeeb nkab yog dab tsi?
Teb: Nws nyob ntawm phab ntsa thickness thiab ua hauj lwm kub. Nyob rau hauv ib txwm kub (20 degree), lub siab tshaj plaws ua hauj lwm siab ntawm 20 # seamless yeeb nkab nrog Φ57 × 3.5mm yog hais txog 10MPa; lub thicker phab ntsa thickness, qhov siab dua cov kabmob siab.
5. Dab tsi yog qhov cuam tshuam toughness ntawm 16Mn carbon steel seamless yeeb nkab?
Teb: Qhov cuam tshuam toughness (Akv) ntawm 16Mn seamless yeeb nkab yog ntau dua los yog sib npaug rau 34J (ntawm 20 degree), uas yog ntau dua li cov pa roj carbon zoo tib yam, yog li nws muaj kev tiv thaiv zoo rau kev cuam tshuam thiab kev co.
