Qhov tseem ceeb sib txawv ntawm A105thiab A105N li qub nyob rau hauv lawv cov txheej txheem kev kho cua sov, thaum lawv cov tshuaj muaj pes tsawg leeg zoo ib yam: A105 yog cov pa roj carbon steel forging tsis muaj lub xeev kev kho cua sov, thaum A105N yuav tsum tau txais kev kho kom zoo los txhim kho microstructure uniformity thiab cov cuab yeej cuab tam stability.
A105 yog tus mob yooj yim, thiab tuaj yeem xa tuaj rau hauv cov txheej txheem annealed, normalized, lossis tsis yog - cua sov- kho mob raws li kev txiav txim. Cov txheej txheem tshwj xeeb yog txiav txim los ntawm cov chaw tsim khoom raws li cov txheej txheem thov. Cov "N" hauv A105N kom meej meej sawv rau "Normalized", uas txhais tau hais tias cov khoom yuav tsum tau rhuab mus txog rau900 degreethiab tom qab ntawd uniformly txias hauv huab cua los ua kom cov nplej, tshem tawm cov kev ntxhov siab sab hauv, thiab txhim kho qhov sib xws ntawm microstructure, yog li tau txais cov khoom ruaj khov dua thiab zoo dua weldability.
Vim nws txoj kev kho kom zoo, A105N yog qhov tsim nyog rau cov ntawv thov uas xav tau cov khoom siv siab, kev cuam tshuam, thiab weldability, xws li siab -siab tshuab, qis- qhov kub thiab txias, los yog tej yam kev mob uas muaj thermal cycling. Ordinary A105 feem ntau yog siv rau hauv qhov kub thiab txias, tsis yog - cov kav dej tseem ceeb, muab qhov zoo ntawm tus nqi- cov haujlwm tseem ceeb.
Nws yog ib qho tsim nyog sau cia tias hauv cov qauv valve xws li ASME B16.34, ntau qhov kev tsim qauv qhia meej meej txog kev siv A105N es tsis yog A105, kom meej meej rau kev txiav txim siab ntawm cov khoom sib xws thiab kev nyab xeeb.
Txawm hais tias koj xav tau A105 tus nqi-kev ua tau zoo lossis A105N kev ua haujlwm-Nyem qhov norau qhov zoo tshaj plaws forged steel valve tov.

FAQ
ASTM A105 txhais li cas?
ASTM A105 yogib qho ntawm feem ntau siv carbon steel specifications forged piping Cheebtsam xws li flanges, fittings, li qub, thiab zoo sib xws. Paub txog nws ntau yam, lub zog, thiab tus nqi -kev ua tau zoo, A105 carbon steel yog dav siv nyob rau hauv lub tshuab siab nrog ambient - thiab siab - qhov kub thiab txias.
Puas yog ASTM A105 casting lossis forging?
A105 yog ibASTM hlau forgingspecification tsuas yog siv rau carbon steel forged piping Cheebtsam. Hom carbon steel forging alloy koom nrog yog cov pa roj carbon tsawg, manganese thiab silicon uas muaj hlau zoo ib yam li AISI 1330, tab sis nrog cov ntsiab lus qis manganese.
Cov khoom siv qib A105N yog dab tsi?
A105N yog acarbon steel forging khoomuas yog dav siv nyob rau hauv manufacturing industrial li qub thiab piping Cheebtsam. Nws muaj cov cuab yeej zoo heev thiab ua haujlwm ntev, ua rau nws haum rau siab - kub thiab siab - ib puag ncig siab.
