ASTM A333 Gr. 3 Tsawg Kub Carbon Steel Yeeb Nkab

ASTM A333 Tsawg-Tsuas Cov Qauv Hlau Yeeb Nkab Taw Qhia

ASTM A333 Gr. 1 qis-kub carbon steel yeeb nkab yog dav siv nyob rau hauv xav tau kev lag luam piping systems. A333 Gr. 3 qis-kub carbon steel yeeb nkab feem ntau yog siv nyob rau hauv qis- qhov kub thiab txias ib puag ncig. Cov hlau no muaj tsawg- mus rau nruab nrab-carbon, silicon, siab -manganese steels nrog cov qauv zoo{12}}cov qauv thiab cov khoom sib xws carbide. Lawv muaj lub zog nruab nrab thiab toughness txog -50℃F (-26 degree). Cov kav dej no tsim nyog rau cov kav dej uas cov txheej txheem dej kub yuav poob mus rau -29℃thaum thov.

Cov hlau no feem ntau yog tsim los rau kev ua haujlwm kub thiab txias. Kub ua hauj lwm raug pom zoo. Tom qab ua haujlwm kub, cov tshuaj annealing thiab quenching feem ntau xav tau. Cov kav dej no tseem tuaj yeem siv ncaj qha yam tsis muaj kev kho cua sov ntxiv. Qhov tseem ceeb, quenching yog qhov tseem ceeb. Txawm hais tias qhov cua sov lossis cua txias qeeb dhau, kev daws teeb meem annealing thiab quenching yog tsim nyog.

Dab tsi yog qhov ua tau zoo ntawm ASTM A333 qis-kub welded kav

Cov alloy no pom zoo ductility thiab formability. Yog li ntawd, qhov tshwm sim ntawm cov khoom tsis ua haujlwm yog tsawg, thiab cov khoom siv kho tshuab yuav tsum tau yooj yim dua. Peb muaj peev xwm ua tau cov txheej txheem vuam feem ntau, txawm tias tsis kam vuam thiab arc vuam. Cov kav dej no muaj kev pheej hmoo tsawg ntawm kev xeb corrosion. Tsis tas li ntawd, nws tuaj yeem welded nrog cov khoom muab tub lim lossis cov khoom siv tsis tau. Lub alloy lub txias ua hauj lwm tso cai rau nws yuav tsum machined siv cov txheej txheem txheem thiab khoom siv. Yog li ntawd, tus nqi ua ntawm cov kav dej no yog qis dua lwm cov yeeb nkab txheem.

A333 Gr 3 qis-kub carbon steel kav yog tsim tshwj xeeb rau kev ua tiav qhov nruab nrab mus rau siab corrosion kuj nyob rau hauv ntau yam kev sib tshuam ib puag ncig. Lub alloy chemistry ntawm qib no ua kom nws zoo heev corrosion kuj. Nws muaj kev ua haujlwm zoo rau pitting corrosion, dav dav corrosion, thiab chloride stress corrosion cracking. Cov kav dej no feem ntau yog siv rau hauv ib puag ncig uas tiv taus cov tshuaj lom neeg hnyav. Tsis tas li ntawd, nws kuj pom zoo tiv thaiv ob qho tib si organic thiab inorganic tebchaw.

vim li cas xaiv peb

GNEE STEEL yog lub tuam txhab xa tawm uas tau koom nrog kev lag luam thoob ntiaj teb steel ntau xyoo. Nrog nws cov khoom siv siab - cov khoom siv zoo thiab cov peev txheej ua haujlwm tshaj lij, nws tau ua tiav cov neeg siv khoom los ntawm ntau lub teb chaws thiab cheeb tsam rau ntawm - qhov chaw mus ntsib thiab tshuaj xyuas. Raws li lub hauv paus no, nws tau ua tiav ntev - lub sij hawm kev koom tes nrog kev sib koom tes thiab txuas ntxiv muab kev lag luam thoob ntiaj teb nrog cov khoom lag luam steel uas ua tau raws li cov qauv thoob ntiaj teb thiab cov kev daws teeb meem ntawm cov saw hlau.
