Tso lus
1.4565 stainless hlau, feem ntau hu ua Alloy 31 lossis UNS N08926, yog ib qho kev ua haujlwm siab -kev ua tau zoo, nitrogen- txhim kho austenitic stainless hlau. Nws yog tsim los muab kev tiv thaiv tshwj xeeb rau ob qho tib si oxidizing thiab txo cov kua qaub, tshwj xeeb tshaj yog sulfuric thiab phosphoric acids, nrog rau cov tshuaj tiv thaiv zoo heev rau chloride-induced pitting thiab crevice corrosion. Qhov no ua rau nws tsim nyog rau kev thov tshuaj ua haujlwm, tswj kev ua qias tuaj, thiab kev siv sab nrauv.
Qhov siab - qib kev ua tau zoo no yog tus qauv raws li cov qauv tseem ceeb thoob ntiaj teb.

Cov yam ntxwv tseem ceeb thiab kev siv ntawm 1.4565 / Alloy 31
Exceptional Acid Resistance:Muab kev tiv thaiv zoo heev rau sulfuric, phosphoric, thiab nitric acids thoob plaws ntau qhov ntau thiab qhov kub thiab txias.
High Pitting thiab Crevice Corrosion Resistance:Nrog rau PREN (Pitting Resistance Equivalent Number) > 40, nws ua tau zoo hauv cov tshuaj chloride- uas muaj ib puag ncig, suav nrog cov dej hiav txwv thiab cov tshuaj brine.
Zoo Weldability thiab Formability:Yuav tau welded siv cov txheej txheem ntau thiab nthuav tawm cov ductility zoo rau kev ua haujlwm.
Cov ntawv thov tseem ceeb:
Kev ua tshuaj lom neeg:Reactors, cua kub exchangers, thiab kav dej rau aggressive acid cov kev pab cuam.
Pollution Control:Scrubbers, ducting, thiab chimney liners hauv flue gas desulfurization (FGD) systems.
Offshore & Marine:Seawater piping, twj, thiab li qub hauv cov nroj tsuag desalination.
Pharmaceutical:Cov cuab yeej tuav cov tshuaj ntxuav corrosive thiab txheej txheem tshuaj.
Alloy 31 (1.4565) piv rau 904L (1.4539) li cas?
Ob leeg yog qib siab - alloy austenitic qib, tab sis Alloy 31 muaj cov qib siab dua ntawm chromium, npib tsib xee, thiab molybdenum, thiab suav nrog nitrogen, muab PREN ntau dua thiab zoo dua rau pitting thiab crevice corrosion. Alloy 31 kuj muaj kev ua tau zoo dua hauv cov kua qaub sib xyaw, tshwj xeeb tshaj yog cov uas muaj sulfuric thiab phosphoric acids. Nws feem ntau suav hais tias yog kev hloov kho los ntawm 904L rau cov mob hnyav dua.
Dab tsi yog cov lus pom zoo rau vuam rau Alloy 31 stainless hlau?
Vuam Alloy 31 yuav tsum sib phim lossis tshaj - alloyed muab tub lim, xws li Alloy 625 lossis siab dua -qib austenitic muab tub lim, kom muaj kev tiv thaiv corrosion hauv thaj tsam weld. Kev tswj cov cua sov tawm thiab cov roj tiv thaiv kom zoo (feem ntau argon-raws li) yog qhov tseem ceeb kom tsis txhob muaj qoob loo ntau dhau thiab nag lossis daus ntawm cov theem tsis zoo. Tom qab-vuam tu yog pom zoo kom rov qab kho corrosion.
