INCOLOY 825 (UNS N08825 / NS142)
Daim ntawv thov
Alloy 825 yog austenitic npib tsib xee-hlau-chromium alloy kuj txhais los ntawm kev ntxiv ntawm molybdenum, tooj liab thiab titanium. Nws tau tsim los muab kev tiv thaiv tshwj xeeb rau ntau qhov chaw corrosive, ob qho tib si oxidizing thiab txo.
Alloy 825 tau tsim los muab kev tiv thaiv tshwj xeeb rau ntau qhov chaw corrosive, ob qho tib si oxidizing thiab txo. Nrog rau cov ntsiab lus npib tsib xee nyob nruab nrab ntawm 38% -46%, qib no qhia tau hais tias tsis kam tiv thaiv kev ntxhov siab corrosion (SCC) cuam tshuam los ntawm chlorides thiab alkalis. Cov ntsiab lus npib tsib xee txaus rau kev tiv thaiv chloride-ion kev ntxhov siab-corrosion tawg. Cov npib tsib xee, ua ke nrog molybdenum thiab tooj liab, kuj tseem ua rau muaj kev tiv thaiv zoo rau kev txo qis ib puag ncig xws li cov uas muaj sulfuric thiab phosphoric acids.
Cov ntsiab lus chromium thiab molybdenum kuj muab cov pitting zoo nyob rau hauv txhua qhov chaw tshwj tsis yog muaj zog oxidizing chloride daws. Siv los ua cov khoom siv tau zoo nyob rau hauv ntau yam txheej txheem ib puag ncig, alloy 825 tswj cov khoom siv zoo los ntawm qhov kub thiab txias txog li 1,000 ° F.
Qhov sib ntxiv ntawm titanium stabilizes Alloy 825 tiv thaiv rhiab heev nyob rau hauv as-welded mob ua lub alloy resistant rau intergranular nres tom qab raug rau kub nyob rau hauv ib tug ntau yam uas yuav sensitize unstabilized stainless hlau. Lub fabrication ntawm Alloy 825 yog ib yam ntawm cov npib tsib xee-puag alloys, nrog rau cov ntaub ntawv tau yooj yim formable thiab weldable los ntawm ntau yam txuj ci.
Cov khoom siv no muaj kev ua tau zoo heev, feem ntau ntawm cov nickel-puag alloys, tso cai rau cov khoom yuav tsum tau khoov mus rau qhov me me radii. Annealing tom qab khoov tsis yog ib txwm tsim nyog.
Nws zoo ib yam li alloy 800 tab sis tau txhim kho kev tiv thaiv aqueous corrosion. Nws muaj kev tiv thaiv zoo heev rau ob qho tib si txo thiab oxidizing acids, rau kev ntxhov siab-corrosion tawg, thiab kev tawm tsam hauv zos xws li pitting thiab crevice corrosion. Alloy 825 tshwj xeeb tshaj yog tiv taus sulfuric thiab phosphoric acids. Cov nickel steel alloy no yog siv rau kev ua tshuaj lom neeg, cov khoom siv tswj cov pa phem, cov kav dej thiab cov pa roj, nuclear roj reprocessing, acid ntau lawm, thiab cov khoom siv pickling.
