ASTM A537 steel hlau

ASTM A537 specification npog cov cua sov kho cov pa roj carbon steel phaj rau kev siv lub nkoj siab.
ASTM A537 Class 1 daim hlau tau muab rau hauv cov xwm txheej zoo li qub thaum Chav Kawm 2 daim hlau yog quenched thiab tempered. ASTM A537 carbon steel daim hlau txhawb zog tensile thiab yield zog ntau dua li cov phaj siab nkag raws li tus qauv ASTM A516.
Gnee Steel tshwj xeeb hauv kev muab cov phaj siab siab uas feem ntau xav tau los ntawm Kev Lag Luam Roj, Roj thiab petrochemical. Peb muab cov khoom siv rau ASTM A537 specification nyob rau hauv ntau qhov ntau thiab tsawg thiab thicknesses kom haum koj cov kev xav tau.
ASTM A537 Qib 1
ASTM A537 Class 1 carbon steel daim hlau yog tsim los siv rau hauv kev siv lub nkoj siab.
Cov khoom siv yog cov hlau tsis zoo uas tau kho cov cua sov thiab ua rau muaj qhov tshwm sim ntau dua thiab lub zog tensile ntau dua li cov qauv ASTM A516 ntau dua. Cov hlau yog zoo tagnrho rau siv nyob rau hauv cov kev pab cuam pressurized ob leeg nyob rau hauv boilers thiab siab hlab ntsha thiab Gnee Steel cov khoom siv A537 Class 1 daim hlau rau lub ntiaj teb no tus thawj fabricators uas nyob rau hauv lem pab rau cov roj, roj thiab Petrochemical kev lag luam.
Peb tuaj yeem muab ASTM A537 Class 1 daim hlau los ntawm Tshuag lossis ncaj qha los ntawm lub tshuab. Peb kuj muab kev pabcuam hauv tsev profile uas cov khoom tuaj yeem txiav rau qhov loj lossis cov duab koj xav tau.

ASTM A537 Qib 2
ASTM A537 Class 2 steel yog cov khoom siv siab dua thiab tensile lub zog siv hauv kev tsim cov hlab ntsha thiab cov boilers steel.
Cov hlau muaj xws li alloying ntawm carbon, manganese thiab silicon thiab kho cua sov siv txoj kev quenched thiab tempered uas muab cov khoom nws residual zog. Tau los ntawm lub ntiaj teb cov thawj coj fabricators, ASTM A537 Chav Kawm 2 yog cov khoom siv dav siv los ntawm kev lag luam roj, roj thiab petrochemical.
Gnee Steel yuav muab ASTM A537 Class 2 daim hlau los ntawm Tshuag lossis ncaj qha los ntawm lub zeb. Peb kuj muab cov kev pab cuam steel xws li CAD raws li nplaim taws txiav txiav koj cov hlau rau hauv cov duab tshwj xeeb.
