Qib 825 steel yog dab tsi?
Alloy 825 (UNS N08825) yog austenitic nickel-hlau-chromium alloy nrog ntxiv molybdenum, tooj liab, thiab titanium. Nws tau tsim los muab kev tiv thaiv corrosion zoo heev hauv oxidizing thiab txo ib puag ncig. Lub alloy resists chloride kev nyuaj siab corrosion cracking thiab pitting corrosion. Qhov sib ntxiv ntawm titanium stabilizes Alloy 825 thiaj li hais tias nws tsis rhiab heev nyob rau hauv lub welded mob, ua lub alloy resistant rau intergranular corrosion tom qab raug rau kub ntau yam uas yuav sensitize tsis ruaj tsis khov stainless hlau. Alloy 825 yog tsim raws li ib tug raug nickel-raws li alloy thiab cov khoom yog yooj yim tsim thiab welded los ntawm ntau yam txuj ci.
Alloy 825 (UNS N08825) yog austenitic nickel-hlau-chromium alloy nrog ntxiv molybdenum, tooj liab, thiab titanium. Nws tau tsim los muab kev tiv thaiv zoo rau ntau qhov chaw corrosive (oxidizing thiab txo).
Cov ntsiab lus npib tsib xee ntawm Alloy 825 ua rau nws resistant rau chloride kev nyuaj siab corrosion cracking thiab, ua ke nrog molybdenum thiab tooj liab, muab kev txhim kho corrosion kuj nyob rau hauv txo ib puag ncig piv rau cov pa austenitic stainless hlau. Cov ntsiab lus chromium thiab molybdenum ntawm Alloy 825 muab kev tiv thaiv rau chloride pitting corrosion nrog rau kev tiv thaiv rau ntau yam oxidizing cua. Qhov sib ntxiv ntawm titanium stabilizes lub alloy thiab tiv thaiv rhiab heev nyob rau hauv lub xeev welded. Qhov kev ruaj ntseg no tso cai rau Alloy 825 los tiv thaiv intergranular nres tom qab raug rau qhov kub thiab txias uas ib txwm ua rau cov hlau tsis ruaj tsis khov.
Alloy 825 muab kev tiv thaiv corrosion nyob rau hauv ntau yam txheej txheem ib puag ncig, suav nrog sulfuric acid, sulfurous acid, phosphoric acid, nitric acid, hydrofluoric acid thiab organic acids thiab cov hauv paus xws li sodium los yog potassium hydroxide, nrog rau cov tshuaj acidic chloride.
Alloy 825 yog tsim raws li ib tug raug nickel-raws li alloy thiab cov khoom yog yooj yim tsim thiab welded los ntawm ntau yam txuj ci.
