A537 Chav Kawm 3yog lub siab lub nkoj steel phaj siv roj thiab roj, petrochemical, thiab siv hluav taws xob tsim hluav taws xob. Nws yog tsim los rau nruab nrab mus rau siab kub thiab muaj zog zoo thiab toughness. Muab nyob rau hauv lub normalized thiab tempered mob, nws muaj ib tug zoo -grained microstructure uas txhim khu nws cov neeg kho tshuab zog. Nws yog feem ntau siv hauv boilers, kub exchangers, thiab lwm yam siab- muaj cov cuab yeej uas yuav tsum tau txhim khu kev qha kev ua tau zoo nyob rau hauv kev ntxhov siab.

daim ntawv thov
Roj thiab Roj: Siv nyob rau hauv cov hlab ntsha siab, cov tso tsheb hlau luam, cov khoom sib cais, thiab cov kav dej rau ob qho tib si onshore thiab offshore, qhov twg lub zog thiab toughness nyob rau hauv siab yog qhov tseem ceeb.
Kev lag luam Petrochemical: Siv nyob rau hauv reactors, txheej txheem tso tsheb hlau luam, thiab cov cuab yeej ua haujlwm tseem ceeb uas tswj qhov kub thiab txias thiab cyclic loading thaum muaj tshuaj lom neeg thiab cov txheej txheem sib cais.
Lub zog tiam: Siv nyob rau hauv cov boiler seem thiab cov khoom siv chav dej uas yuav tsum tau ua siab ntev -siab chav thiab rov ua dua thermal cycling.
Kev ua tshuaj lom neeg: Xaiv rau nruab nrab - lub tank tso siab thiab cov hlab ntsha uas muaj ntau yam tshuaj, qhov kev ua tau zoo ntawm cov qauv tsim nyog yuav tsum muaj nyob rau hauv ntau yam kev ua haujlwm.
