P355NH hlauyog tus cwj pwm los ntawm qhov zoo weldability thiab siab ua haujlwm rau brittle cracking. Cov hom no yog siv saum toj no tag nrho rau kev tsim cov hlab ntsha rau cov pa roj (LPG, butane thiab propane tso tsheb hlau luam), cov hlab ntsha siab, qhov chaw rau chav boilers, siab piping, compressors, thiab lwm yam.
P355NH steel yog muab nyob rau hauv lub normalized mob. Lub normalizing kub yog 900 - 950 ºC, thiab nws yuav tsum tau muab tso rau hauv lub cub tawg tom qab kub sib npaug zos rau kwv yees li 1 feeb ib millimeter thickness ntawm lub phaj. Raws li qhov tshwm sim, nws muaj qhov txias txias zoo - ua thiab kub - tsim cov khoom yam tsis muaj kev cuam tshuam rau cov khoom siv.
Cov hlau zoo grained hauv cov koob no tuaj yeem ua tau zoo kawg nkaus welded, ob qho tib si manually thiab siv cov khoom siv tsis siv neeg, los ntawm txhua qhov kev paub vuam txheej txheem.

Cov yam ntxwv tseem ceeb thiab kev siv ntawm P355NH siab hlab ntsha hlau
Siab Vessel Steel: P355NH siab hlab ntsha hlau yog tsim tshwj xeeb rau kev siv hauv cov hlab ntsha siab thiab boilers, qhov uas nws yuav tsum tau tiv taus siab - siab. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev lag luam uas xav tau cov ntaub ntawv muaj peev xwm tiv taus qhov xav tau ib puag ncig.
Normalized thiab Fine- Cov Qauv Nplej: P355NH ua haujlwm zoo li qub, tswj cov cua sov thiab cua txias uas ua kom zoo dua nws cov qauv nplej. Cov txheej txheem no txhim kho cov hlau cov cuab yeej cuab tam, suav nrog toughness thiab lub zog, thiab ua rau nws tsim tshwj xeeb rau kev siv vuam.
Siab kub Resistance: Cov hlau tau tsim kho kom ua tau zoo ntawm qhov kub siab, kom ntseeg tau tias nws tuav nws lub zog thiab kev ntseeg ruaj khov txawm tias nyob rau hauv siab - qhov kub thiab txias. Qhov no yog qhov tseem ceeb rau cov ntawv thov uas muaj cov boilers thiab cov hlab ntsha siab uas ua haujlwm ntawm qhov kub siab.
Tshuaj muaj pes tsawg leeg: P355NH muaj cov ntsiab lus xws li carbon, manganese, phosphorus, sulfur, silicon, thiab cov lej ntawm lwm yam alloying. Cov muaj pes tsawg leeg yog ua tib zoo tswj kom ua tau raws li qhov yuav tsum tau muaj cov khoom siv thiab cov qauv toughness.
Ua raws li Cov Qauv: P355NH steel ua raws li European cov qauv, suav nrog EN 10028-3, ua kom ntseeg tau zoo thiab ua haujlwm zoo hauv kev siv lub nkoj siab.
Ntau yam: Tshaj li cov hlab ntsha siab thiab cov boilers, P355NH steel tuaj yeem pom daim ntawv thov hauv cov khoom siv hluav taws xob, cov kav dej, thiab cov tso tsheb hlau luam hauv ntau qhov kev lag luam uas xav tau cov ntaub ntawv muaj peev xwm tiv taus siab - siab thiab siab - qhov kub thiab txias.
Weldability: P355NH steel exhibits zoo heev weldability, tso cai rau nws tau yooj yim welded siv cov pa vuam txheej txheem. Cov cuab yeej no yooj yim rau kev tsim cov txheej txheem rau cov hlab ntsha siab thiab ua kom cov pob qij txha txhim khu kev qha.
Corrosion Resistance: Thaum P355NH tsis yog qhov muaj zog corrosion- tiv taus, nws tuaj yeem tiv thaiv corrosion los ntawm kev kho kom zoo los yog txheej txheej, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas raug cov tshuaj corrosive yog ib qho kev txhawj xeeb.
