Daim ntawv thov

Lub Nkoj Siab & Reactors:Lub ntsiab tseem ceeb rau siab - muaj siab nyob rau hauv cov roj refining thiab chemical processing.

Cia Tank:Siv rau loj API 650/620 tso tsheb hlau luam, nrog rau cov tso tsheb hlau luam cryogenic.

Boilers & Kub Exchangers:Haum rau hnyav-lub luag haujlwm muaj boilers, pressurizers, thiab chav generators.

Offshore Engineering:Siv nyob rau hauv sib sib zog nqus- cov khoom siv dej hiav txwv vim hnyav ib puag ncig haum.

Kev tsim hluav taws xob:Cheebtsam nyob rau hauv nuclear steam generators thiab fais fab nroj tsuag.

Qhov zoo

Siab zog:Muab cov txiaj ntsig zoo dua thiab lub zog tensile dua li Chav Kawm 1, tuav cov khoom hnyav dua.

Zoo heev Toughness:Muab kev puas tsuaj zoo tshaj plaws, txawm tias nyob rau hauv dynamic lossis poob siab loading.

Versatile Performance:Ua tau zoo nyob rau hauv siab -siab, siab- kub, thiab qis- kub (cryogenic) tej yam kev mob.

Zoo Weldability:Yooj yim fabricated siv cov txheej txheem vuam txheej txheem.

Corrosion Resistance:Kev tiv thaiv zoo, tshwj xeeb tshaj yog nyob rau hauv hnyav kev lag luam ib puag ncig.

Tus nqi -Kev Tsim Nyog:Lub zog siab tso cai rau cov phaj nyias nyias, txo cov khoom hnyav thiab tus nqi.

Txhim khu kev ruaj ntseg:Nws cov khoom muaj zog ua kom muaj kev ntseeg siab thiab txhim kho kev nyab xeeb hauv cov khoom siv tseem ceeb.

A537 Chav Kawm 2 yog dab tsi?

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.

Dab tsi yog qhov muaj pes tsawg leeg ntawm A537 steel?

Chemical Composition: ASTM A537 feem ntau muaj cov pa roj carbon, manganese, phosphorus, thiab sulfur, nrog rau kev tsom mus rau qee qhov tshwj xeeb kom ua tiav cov khoom siv kho tshuab xav tau.
