Ua ib lub tuam txhab muag khoom lag luam tseem ceeb, peb muab cov ntawv pov thawjVuam Electrode E2594(AWS A5.4 E2594-16), lub npe lag luam AF2594-16. Lub titanium calcium-coated, ultra-low carbon duplex stainless hlau electrode no muaj cov ntsiab lus nitrogen zoo tshaj plaws los xa cov tshuaj tiv thaiv corrosion zoo heev. Nws cov tshuaj tshwj xeeb tsim cov hlau weld nrog kev tiv thaiv zoo dua rau pitting, kev ntxhov siab corrosion cracking (SCC), thiab thermal cracking–tshwj xeeb tshaj yog tseem ceeb rau cov chaw muaj chloride ntau xws li cov chaw ua tshuaj lom neeg thiab cov chaw tsim khoom hauv hiav txwv uas cov hlau tsis xeb ua haujlwm tsis zoo.
Lub electrode'Qhov ua tau zoo ntawm nws cov khoom siv uas tsis muaj carbon ntau (feem ntau <0.03% C) ua ke nrog nitrogen thiab molybdenum txhim kho. Qhov no ua tiav qhov Pitting Resistance Equivalent (PRE) ntawm 2-40 thaum tswj hwm qhov sib npaug ntawm austenite-ferrite microstructure. Tus qauv tsim hlau tiv thaiv kev xeb intergranular thiab khaws cia qhov cuam tshuam toughness thoob plaws qhov kub thiab txias ntawm cov xwm txheej cryogenic mus rau 300°C (572°F), ua tau raws li qhov yuav tsum tau ua ntawm AWS A5.4.
Hauv kev ua haujlwm, qhov noVuam Electrode E2594Nws muaj cov txheej txheem titanium-calcium zoo tshaj plaws uas ua kom muaj kev ruaj khov DC + arc thiab tshem tawm slag hauv txhua qhov chaw, suav nrog kev siv ntsug. Cov txheej txheem no txo qis kev nqus hydrogen (<5ml/100g), tshem tawm cov kev pheej hmoo ntawm kev tawg txias hauv cov pob qij txha uas muaj kev txwv siab. Cov neeg vuam qhia txog kev hloov pauv hlau du nrog qhov tsawg kawg nkaus spatter thiab yooj yim restrikes, txhim kho kev tsim khoom hauv cov ntawv thov tseem ceeb xws li kev tsim cov hlab siab thiab kev vuam kav dej.
Kev ua tau zoo lees paub qhov sib piv ntawm cov hlau vuam uas muaj 25.5% Cr, 9.5% Ni, 3.8% Mo, thiab 0.22% N. Kev sim ASTM G48 Txoj Kev A ywj pheej qhia tau tias qhov kev tiv thaiv xeb pitting siab dua li cov qib duplex ib txwm muaj los ntawm 40.°C (104°F). Qhov kev tswj hwm 45/55 ferrite-austenite theem sib npaug muab cov txiaj ntsig ntawm 650-750 MPa (94-109 ksi) nrog 25% + elongation–ua tau raws li ASME, EN, thiab NORSOK cov lus qhia rau cov khoom siv tseem ceeb.
Rau cov ntawv thov corrosion hnyav,Vuam Electrode E2594tseem yog tus qauv kev lag luam. Nws qhov kev ua tau zoo hauv cov txheej txheem desalination, cov platforms offshore, thiab cov tshuaj reactors ua kom ntseeg tau tias muaj kev ntseeg siab. Muab rau hauv 4kg ntim khoom uas kaw nrog lub sijhawm txee 36 lub hlis, txhua yam khoom siv suav nrog cov ntawv pov thawj tshwj xeeb. Tiv tauj peb pab neeg txog kev siv vuam tshwj xeeb.
