ASTM A537 Qib 2yog lub siab -lub zog steel rau welded siab hlab ntsha, featuring quenching thiab tempering kom ua tiav cov khoom siv kho kom zoo.
Nws sawv tawm hauv ASTM A537 steel phaj tsev neeg rau nws lub peev xwm los daws cov kev kub ntxhov siab thiab cov kev pabcuam qaub, qhov twg hydrogen -induced cracking yog qhov txaus ntshai.
Kev kho cua sov-quenching hauv dej / roj tom qab austenitizing, ua raws li tempering- tsim kom muaj microstructure zoo rau superior hardness thiab ductility.
Ntawm Gangsteel, peb muab daim hlau ua raws li ASME SA537 / SA537M steel phaj qauv, siv nyob rau hauv reactor hlab ntsha, cia tank, thiab kub exchangers.

daim ntawv thov
Cov hlab ntsha thiab boilers:
Welded siab hlab ntsha, boilers, thiab siab- khaws cov khoom uas yuav tsum tau zoo tsawg- kub toughness thiab txhim khu kev qha kev ua tau zoo nyob rau hauv nruab nrab mus rau siab siab thiab kub.
Kev lag luam roj thiab roj:
Offshore platforms, tanks loj, pipelines -cov cuab yeej muaj feem xyuam, thiab cov nkoj refinery tuav hydrocarbons thiab cov txheej txheem dej.
Petrochemical thiab chemical processing:
Reactors, distillation kab, txheej txheem hlab ntsha, thiab tshav kub exchangers raug rau cyclic loading thiab ntau yam txheej txheem ib puag ncig.
Kev tsim hluav taws xob:
Boiler Cheebtsam, cov cuab yeej siv hluav taws xob rov qab, thiab cov hlab ntsha siab hauv thermal thiab ua ke - voj voog fais fab nroj tsuag.
Kev siv dav dav:
Heavy-cov haujlwm welded cov qauv thiab cov khoom siv uas muaj lub zog siab, zoo weldability, thiab tiv taus cov pob txha tawg yog xav tau.
Qhov zoo:
High Strength & Toughness:Muab cov txiaj ntsig zoo dua thiab lub zog tensile ntau dua li Chav Kawm 1, muab kev tiv thaiv zoo dua rau cov khoom siv hluav taws xob / kev poob siab thiab txo qhov kev pheej hmoo ntawm kev tawg ntawm qhov kub thiab txias.
Superior Weldability:Nws muaj pes tsawg leeg thiab kev kho cua sov (quenching & tempering) ua rau nws zoo heev weldable, txawm nyob rau hauv cov xwm txheej nyuaj, siv tsawg -hydrogen electrodes.
Enhanced Safety & Reliability:Kev sib xyaw ua ke ntawm lub zog thiab lub zog ua kom muaj kev nyab xeeb ua haujlwm nyob rau hauv siab - ib puag ncig siab, ua rau muaj kev pab cuam lub neej thiab txo kev txij nkawm.
Tus nqi -Kev Tsim Nyog:Nws lub zog siab tso cai rau kev tsim cov phaj nyias nyias, txo qhov hnyav tag nrho thiab cov nqi khoom siv rau cov hlab ntsha siab.
Kev Ua Tau Zoo Tshaj Plaws hauv Hnyav Ib puag ncig:Tiv thaiv hydrogen cracking (HIC) thiab ua tau zoo nyob rau hauv siab -kub, siab - siab, thiab qaub (sulfur{2}} nplua nuj) daim ntawv thov kev pab.
Zoo machinability:Muab cov machinability zoo, simplifying fabrication txheej txheem.
