1. ASTM SA210 yog dab tsi?
ASTM SA210 yog tus qauv tshwj xeeb rau seamless nruab nrab - carbon steel boiler thiab superheater tubes, feem ntau yog siv hauv siab - qhov kev pab cuam kub. Nws suav nrog qib A-1 thiab C, uas txhais cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab.
2.Dab tsi yog cov qib sib txawv raws li ASTM SA210?
ASTM SA210 suav nrog ob qib tseem ceeb: Qib A-1 thiab Qib C. Qib A-1 yog cov hlau nruab nrab uas muaj zog qis, thaum Qib C muaj cov ntsiab lus carbon ntau dua thiab txhim kho tensile zog rau kev thov ntau dua.
3.Dab tsi yog cov ntawv thov tseem ceeb ntawm ASTM SA210 steel hlab?
Cov raj no feem ntau yog siv rau hauv boilers, superheaters, heat exchangers, thiab lwm yam siab hlab ntsha nyob rau hauv lub hwj chim nroj tsuag, industrial cua sov systems, thiab refineries qhov twg siab - kub thiab siab kuj yuav tsum tau.
4.Dab tsi yog cov khoom siv kho tshuab rau ASTM SA210 raj?
Rau Qib A-1, lub zog tensile yog 380 MPa min, yield zog yog 205 MPa min, thiab elongation yog 30% min. Qib C muaj qhov tseem ceeb dua: tensile zog ntawm 485 MPa min, yield zog ntawm 275 MPa min, thiab elongation ntawm 30% min.
5.Yuav ua li cas yog ASTM SA210 steel tubes tsim?
Lawv feem ntau yog ua los ntawm seamless raj los ntawm cov txheej txheem xws li kub dov lossis txias txias, ua raws li kev kho cua sov (xws li, normalizing lossis annealing) kom ua tiav cov khoom siv kho tshuab thiab microstructure.
