Khoom Description
A537CL siab hlab ntsha steel phaj yog cov pa roj carbon tsawg manganese steel phaj siv hauv kev tsim cov hlab ntsha kub resistant.
(1) American standard SA537 steel phaj cais yog: SA537CL1 / SA537MCL1, SA537CL2 / SA537MCL2, SA537CL3 / SA537MCL3 yog kwv yees faib ua peb qib.
(2) Manganese silicon steel phaj A537CL2 thiab A537CL3 yog cov cua sov kho nrog kev kho cua sov rau cov hlab ntsha siab, thiab Asmeskas tus qauv (A537/A537M-95) raug xaiv rau quenching thiab tempering tus me nyuam, thiab A537CL1 yog xaiv rau normalizing tus me nyuam .
(3) Ua raws li txoj cai: ua raws li American code ASME SA537 / SA537M.
A537CL siab nkoj steel phaj nta yog raws li nram no:
1. Nws muaj qhov kub thiab txias tsis kam, haum rau qhov kub thiab txias ib puag ncig siab lub nkoj tsim khoom;
2. Muaj lub zog tensile zoo thiab lub zog tawm los, tuaj yeem siv los tsim cov hlab ntsha siab thiab cov kav dej;
3. Zoo weldability thiab kev ua tau zoo.
Daim ntawv thov ntau yam ntawm A537CL siab lub nkoj steel phaj suav nrog: Daim ntawv thov ntau yam ntawm A537CL siab nkoj steel phaj yog tsuas yog tsim cov hlab ntsha kub siab, xws li kub cia tank, reactors, tshav kub exchangers, separators, yees thiab lwm yam khoom siv hauv roj av, chemical, roj cia thiab kev thauj mus los kev lag luam. Tib lub sijhawm, A537CL steel phaj kuj tuaj yeem siv los tsim cov boilers, cov hlab ntsha siab thiab lwm yam khoom siv. Vim tias A537CL steel phaj muaj qhov kub thiab txias tsis kam thiab lub zog siab, nws muaj kev ruaj ntseg zoo thiab kev ntseeg siab nyob rau hauv qhov kub thiab txias ib puag ncig.
Cov teeb meem tshwm sim hauv kev siv A537CL siab nkoj steel phaj suav nrog: Cov teeb meem hauv qab no yuav tshwm sim hauv kev siv A537CL siab nkoj steel phaj:
1. Corrosion: Vim hais tias A537CL steel phaj yog siv los tsim cov hlab ntsha kub siab, sab hauv ntawm lub thawv feem ntau yog kub thiab siab siab gas los yog kua, qhov saum npoo ntawm lub thawv phab ntsa yog qhov cuam tshuam rau corrosion, uas ua rau corrosion los yog xeb. nyob rau saum npoo ntawm steel phaj.
2. Kev qaug zog: Thaum lub sij hawm siv lub thawv rau lub sijhawm ntev, vim muaj kev cuam tshuam ntawm lub voj voog, cov kab nrib pleb tuaj yeem tshwm rau ntawm phab ntsa ntawm lub thawv, uas ua rau lub thawv tsis ua haujlwm.
3. Hydrogen-induced cracking: nyob rau hauv qhov kub thiab txias ib puag ncig, cov hydrogen nyob rau hauv lub thawv yog ib qho yooj yim rau nkag mus rau hauv cov hlau phaj, uas ua rau tsim hydrogen-induced cracking, uas cuam tshuam rau kev nyab xeeb kev ua tau zoo ntawm lub thawv.
Yog li ntawd, thaum siv A537CL siab hlab ntsha steel phaj, nws yog ib qho tsim nyog yuav tsum tau them sai sai rau qhov chaw ntawm cov hlau phaj, lub thawv ntim khoom, kev nkag mus ntawm hydrogen, thiab lwm yam. ntawm lub thawv.
