ASTM A537 Qib 1yog ib hom carbon-manganese-silicon siab hlab ntsha hlau uas tau raug normalized kom ua tau zoo ua ke ntawm lub zog thiab toughness. Nws yog tsim tshwj xeeb rau kev siv nyob rau hauv welded siab-muaj cov qauv uas txhim khu kev qha kev ua tau zoo ntawm nruab nrab thiab qis kub yuav tsum tau. Cov ntaub ntawv pov thawj weldability zoo heev, tso cai rau cov fabricators los tsim cov hlab ntsha loj thiab nyuaj yam tsis muaj kev pheej hmoo ntawm kev tawg thaum lossis tom qab vuam. Nws cov tawv tawv ua rau nws haum rau cov kev pab cuam qhov twg thermal cycling los yog qis-kub raug lwm yam yuav ua rau nkig tsis ua hauj lwm. Qib no feem ntau raug xaiv rau cov ntawv thov hauv cov roj, roj, thiab petrochemical kev lag luam, nrog rau cov boilers, cia tank, thiab lwm yam khoom siv siab uas yuav tsum muaj kev ruaj ntseg raws li qhov xav tau ntawm kev ua haujlwm.

Daim ntawv thov ntawm ASTM A537 Class 1
Cov Khoom Siv Hluav Taws Xob & Boilers:
ASTM A537 Chav Kawm 1 yog siv dav hauv kev tsim cov welded siab hlab ntsha thiab boilers uas ua haujlwm ntawm qhov nruab nrab thiab qis. Nws cov microstructure normalized muab qhov sib npaug zoo ntawm lub zog thiab tawv, ua rau nws tsim nyog rau cov khoom siv uas muaj kev cuam tshuam sab hauv, thermal cycling, thiab sib txawv load. Cov khoom siv no feem ntau yog xaiv rau cov txheej txheem cov hlab ntsha, cov nruas boiler, thiab lwm yam siab - muaj cov khoom siv uas txhim khu kev qha thiab kev tiv thaiv kom tawg tawg yog qhov tseem ceeb.
Roj & Roj Kev Lag Luam:
Hauv kev lag luam roj thiab roj, A537 Chav Kawm 1 yog dav siv rau kev tsim kho cov tank cia ua rau API cov qauv, nrog rau ntau yam khoom siv hauv cov chaw pabcuam me me. Nws zoo heev weldability thiab formability ua rau nws yog ib tug tswv yim xaiv rau loj, welded lug xws li crude roj tso tsheb hlau luam, khoom cia tank, thiab lwm yam hlab ntsha uas yuav tsum tau durability thiab ntev kev pab cuam lub neej. Cov khoom siv tawv kuj tso cai rau nws ua haujlwm zoo nyob rau sab nraum zoov thiab qhov kub thiab txias uas feem ntau pom nyob rau hauv ntau qhov chaw roj thiab roj.
Thaum tshav kub kub Exchangers:
A537 Chav Kawm 1 yog tsim los siv rau hauv cov khoom siv hluav taws xob sib txawv thiab cov khoom siv sib xws, nrog rau cov plhaub, cov ntawv, thiab lwm yam khoom uas hloov cov cua sov ntawm cov kua. Nws muaj peev xwm tswj tau lub zog thiab lub zog nyob rau hauv qhov ntsuas kub nruab nrab, ua ke nrog nws cov weldability zoo, ua rau nws muaj kev ntseeg siab rau kev sib pauv cua sov hauv cov chaw ua haujlwm, cov nroj tsuag tshuaj, thiab cov chaw tsim hluav taws xob. Cov khoom siv tiv thaiv kev ntxhov siab thermal thiab nws cov khoom siv kho tshuab ruaj khov ntxiv txhim kho nws qhov tsim nyog rau cov ntawv thov no.
