ST52 alloy steel yeeb nkab chaw tsim tshuaj paus kev ruaj ntseg zoo
Cov hlau tsis muaj hlau yog suav tias yog cov qauv hlau zoo tib yam, uas yog tshwj xeeb los ntawm lub zog tensile thiab qhov taw tes tawm. Nws yog siv nyob rau hauv kev tsim kho vaj tse, underground engineering, choj qauv, marine qauv, thawv manufacturing, tsheb thiab tshuab manufacturing.
Qib steel feem ntau yog tsim los ntawm tsab ntawv st, tus yam ntxwv tus nqi ntawm cov hlau thiab qhov ntsuas zoo. Piv txwv li, St52-3. Rau cov qib steel nrog qee yam kev xaiv rau txoj kev deoxidation, cov cim sib thooj (U lossis R) tau muab tso rau pem hauv ntej ntawm qib steel.
Piv txwv li: ust37-2 los yog rst37-2
Me hom st37-2 st37-3u st37-3n hloov 20 steel
St37 yog ib hom German, tab sis nws yog hom dav dav thiab ntau lub npe me.
Xws li st37-2, st37-3u, st37-3n, rst-2, ust37-2, thiab lwm yam.
St37-2 yog ib hom ntawm carbon structural steel nyob rau hauv lub teb chaws Yelemees
Cov khoom no yog sib npaug rau carbon structural steel Q235B (qub hom naj npawb: a3-b) hauv Suav teb
Tsis tas li ntawd, vim tias cov hlau no zoo ib yam li Tuam Tshoj cov khoom siv zoo carbon steel 20 steel, nws tuaj yeem hloov tau los ntawm 20 steel.
Kev kub siab seamless steel yeeb nkab thiab siab siab boiler yeeb nkab yog ib hom boiler yeeb nkab, teej tug mus rau qeb ntawm seamless steel yeeb nkab. Txoj kev tsim khoom yog tib yam li cov yeeb nkab seamless, tab sis muaj cov kev cai nruj rau cov qib steel siv hauv kev tsim cov yeeb nkab steel. Kev kub siab boiler raj feem ntau yog siv nyob rau hauv qhov kub thiab txias siab. Kev kub siab boiler raj feem ntau yog siv los tsim cov raj superheater, reheater raj, cua ducts, lub ntsiab chav boilers, thiab lwm yam ntawm high-pressure thiab ultra-high-pressure boilers.
