ASTM SA210 GRAPuas muaj cov hlau pheej yig (CURN0.27%), muaj cov ntsiab lus xws li manganese (SI 0.10-0.20%) kom ntseeg tau cov khoom siv zoo thiab cov txheej txheem zoo.

Tsawg sulfur thiab phosphorus cov ntsiab lus (C≤0.035%, SUR0.035%) txhim kho cov ntsuas kub siab oxidation tiv thaiv.

Kev ua tau zoo heev

Kev kub siab ua hauj: ntev ua hauj lwm ua hauj lwm sov ≤450 ℃, luv luv txog rau 480 ℃.

Cov kabmob siab: haum rau nruab nrab thiab qis siab boiler kav dej ≤5,88MPA.

Cov txheej txheem sib xyaw: Yooj yim rau weld, khoov thiab ua kom txias, haum rau boiler cov thawv, headers thiab lwm yam.

Nruj qauv

Ua raws liASTM SA210 GRACov Qauv, Thiab PassGB / T 3087, ASME thiab lwm yam ntawv pov thawj kom muaj kev nyab xeeb thiab kev ntseeg tau.

ASTM SA210 gra Seamless steel yeeb nkab yog qhov kev xaiv zoo tshaj plaws rau cov teb hauv qab no:

Boiler Kev Lag Luam: Boiler Dej Phab Ntsa, Superheater, Accuarizer Thiab Lwm Yam Tseem Ceeb.

Kev hloov kho cua sov: condenser thiab evaporator kav dej hauv petrochemical kev lag luam.

Fais fab zog: Chav sib kis mus rau lub sam thiaj thiab cov tshuab ntsuas ntawm thermal fais fab nroj tsuag.

Tus nqi-txiaj ntsig: piv nrog Alloy Steel Kave, ASTM SA210 GRA cov nqi ua lag luam thaum lub rooj sib tham xav tau.

Cov khoom siv tsis ruaj khov: Ua cov khoom lag luam dav dav siv, cov khoom lag luam muaj txaus thiab kev xa khoom tuaj ntev.

Peb muab cov kev txiav customized, tsis yog-kev ua phem tshaj tawm (ut / RT), cov ntaub ntawv qhia txog ASTM SA210 GRA Seamless Steel Kav, thiab txhawb nqa cov khoom lag luam thoob ntiaj teb.

ASTM SA210 GRACarbon Steel seamless yeeb nkab tau dhau los ua cov khoom lag luam hauv lub tshav boilers thiab kev hloov cua sov vim nws txoj kev lag luam ruaj khov thiab kev lag luam. Yog tias koj xav tau kev tsis muaj tseeb lossis cov nqe lus hais, thov hu rau peb pab neeg tshaj lij!
