Exceptional Resistance rau Pitting thiab Crevice Corrosion
Cov nyhuv synergistic ntawm siab molybdenum (15-17%), chromium (14.5-16.5%), thiab tungsten (3-4.5%) muab qhov zoo tshaj plaws hauv zos corrosion kuj piv rau 316L, 317L, thiab txawm tias feem ntau super austenitic stainless hlau (piv txwv li, 6Mo) nyob rau hauv muaj zog corrosive sulfuric acid, halogen sulfuric media. acid, formic acid, acetic acid, thiab lwm yam.
Zoo heev Resistance rau Chloride Stress Corrosion Cracking
Nws cov ntsiab lus npib tsib xee siab (tseem tshuav, kwv yees li 57%) ua rau nws muaj zog tiv thaiv chloride-induced stress corrosion cracking. Nws ua tau zoo heev nyob rau hauv marine ib puag ncig, dej ntsev txias, evaporators, thiab cov txheej txheem tshuaj, ua tau zoo tshaj 304, 316, thiab duplex stainless hlau.
Superior Corrosion Resistance rau Txo thiab Oxidizing Acids
Nws pom zoo corrosion kuj nyob rau hauv xov xwm xws li sulfuric acid, hydrochloric acid, phosphoric acid, formic acid, acetic acid, thiab hydrofluoric acid. Tsis tas li ntawd, nws qhia tau hais tias kev ua tau zoo tiv thaiv oxidizing acids (piv txwv li, nitric acid, acid tov uas muaj Fe³⁺/Cu²⁺), ua rau nws haum rau ntau yam hnyav reactors, tshav kub exchangers, thiab piping systems.
Zoo Fabrication thiab Weldability
Nws tuaj yeem tsim los ntawm cov qauv ua haujlwm kub thiab txias. Nws muaj qhov zoo tshaj plaws weldability, sib xws nrog cov txheej txheem vuam xws li GTAW, GMAW, SMAW, thiab SAW. Tom qab-weld kev kho cua sov tsis tas yuav tsum tau ua (tab sis qhov kub sib txawv yuav tsum tau tswj), ua kom yooj yim rau kev tsim cov cuab yeej siv.

High -kev ua haujlwm kub
Nws pom zoo oxidation kuj nyob rau hauv oxidizing cua hauv qab 1000 degree. Txawm li cas los xij, cov hlau no feem ntau yog tsim los rau nruab nrab - thiab qis - qhov kub thiab txias corrosive ib puag ncig (ntev- siv sijhawm tsawg dua lossis sib npaug li 450℃). Phase stability yuav tsum tau txiav txim siab saum toj no kub.
