Koj paub dab tsi txog forging A105?

Txheem lub npe: carbon steel forgings rau cov yeeb nkab qhov chaw.
Vim tsuas yog ib hom carbon hlauforgingtau teev nyob rau hauv tus qauv no, A105 kuj suav hais tias yog carbon steel qib ntawm forging.
A105 kuj yog cov khoom siv code, uas belongs rau cov hlau tshwj xeeb thiab yog cov hlau forged txias.
A105yog ib qho qis carbon steel forging, zoo ib yam li 20 steel. Muaj ob tus qauv, ib qho yog Asmeskas tus qauv ASTM A105 / A105M Carbon Steel Forgings rau Piping Cheebtsam, thiab lwm yam yog Suav tus qauv GB / T12228-2006 Cov Txheej Txheem Txheej Txheem rau Carbon Steel Forgings rau General Purpose Li qub.

A105 carbon steel qauv
A105 yog Asmeskas tus qauv ASTM tus lej, ASTM A105 / A105M carbon steel forgings rau cov khoom siv yeeb nkab, thiab A sawv cev rau cov pa roj carbon zoo tib yam. Nws belongs rau cov hlau tshwj xeeb thiab yog hom txias forged steel. A105 yog cov hlau tsis tshua muaj hlau forging, zoo ib yam li 20 steel.
Lus Cim: Hauv cov kav dej, feem ntau A105 tuaj yeem hloov tsis tau 20, tab sis No. 20 tsis tuaj yeem hloov A105 kiag li, vim qhov sib txawv ntawm lub zog tseem loj. Txawm li cas los xij, qhov kev ntxhov siab corrosion cracking (SCC) tsis kam ntawm A105 yog me ntsis phem dua li ntawm No. 20.

A105 Cov khoom siv twg yog qhov txawv ntawm 20 steel
A105 yog cov hlau tsis tshua muaj hlau forging. Cov ntsiab lus carbon ntawm cov qauv hlau yog li 0.05% ~ 0.70%, thiab qee qhov tuaj yeem siab txog 0.90%. A105 yog Asmeskas tus qauv ASTM tus lej, thiab A sawv cev rau cov qauv carbon zoo tib yam. Hauv cov qauv no, tsuas yog ib hom carbon steel forging tau teev tseg, thiab A105 kuj suav tias yog qib carbon steel ntawm forging. A105 kuj yog cov khoom siv code, uas belongs rau cov hlau tshwj xeeb thiab yog cov hlau forged txias. A105 yog ib qho qis carbon steel forging, zoo ib yam li 20 steel. Muaj ob tus qauv, ib qho yog Asmeskas tus qauv ASTM A105 / A105M Carbon Steel Forgings rau Piping Cheebtsam, thiab lwm yam yog Suav tus qauv GB / T12228-2006 Cov Txheej Txheem Txheej Txheem rau Carbon Steel Forgings rau General Purpose Li qub. Cov ntsiab lus carbon ntawm cov qauv hlau yog li 0.05% ~ 0.70%, thiab qee qhov tuaj yeem siab txog 0.90%. Hauv cov kav dej, feem ntau A105 tuaj yeem hloov tsis tau 20, tab sis No. 20 tsis tuaj yeem hloov A105 kiag li, vim qhov sib txawv ntawm lub zog tseem loj. Txawm li cas los xij, qhov kev ntxhov siab corrosion cracking (SCC) tsis kam ntawm A105 yog me ntsis phem dua li ntawm No. 20.
Nws tuaj yeem muab faib ua cov pa roj carbon monoxide zoo tib yam thiab cov khoom siv zoo carbon steel. Nws muaj ntau yam siv thiab siv ntau npaum li cas. Nws yog tsuas yog siv nyob rau hauv railway, choj, ntau yam kev tsim kho tej yaam num, tsim ntau yam hlau Cheebtsam uas dais static loads, thiab tsis tseem ceeb txhua yam qhov chaw thiab dav weldments uas tsis xav tau kev kho cua sov.
