Vim li cas Alloy N155?
Alloy N155 muaj kev tiv thaiv zoo rau corrosion nyob rau hauv tej yam xov xwm nyob rau hauv ob qho tib si oxidizing thiab txo tej yam kev mob.Thaum cov tshuaj kho cua sov kho, alloy N155 alloy muaj txog tib yam tsis kam rau nitric acid ib yam li stainless hlau.Nws muaj kev tiv thaiv zoo dua li cov hlau tsis muaj zog rau cov tshuaj tsis muaj zog ntawm hydrochloric acid.Nws tiv taus tag nrho cov concentrations ntawm sulfuric acid nyob rau hauv chav tsev kub.Cov hlau tuaj yeem raug machined, forged thiab txias-tsim los ntawm cov txheej txheem pa.
Lub alloy tuaj yeem welded los ntawm ntau yam arc thiab tsis kam-welding txheej txheem.Cov hlau no muaj xws li daim ntawv, sawb, phaj, hlau, coated electrodes, billet Tshuag thiab sane thiab peev castings.
Nws kuj tseem muaj nyob rau hauv daim ntawv ntawm cov khoom rov ua dua mus rau cov ntawv pov thawj chemistry.Feem ntau cov ntaub ntawv wrought ntawm n155 alloy raug xa mus rau hauv cov tshuaj kho cua sov kom paub tseeb tias cov khoom zoo.Daim ntawv yog muab cov kev daws teeb meem kub-kho ntawm 2150 ° F, rau ib lub sij hawm nyob ntawm cov thickness, ua raws li cov cua txias los yog dej quench.Bar Tshuag thiab phaj (1/4 nyob rau hauv. thiab hnyav dua) feem ntau yog cov tshuaj kho cua sov ntawm 2150 ° F ua raws li dej quench.
Alloy N155 raug kev txom nyem los ntawm nruab nrab oxidation tsis kam, ib tug nyiam rau tshav kub cuam tshuam cheeb tsam tawg thaum lub sij hawm vuam, thiab ib tug kuj dav scatter band ntawm txhua yam khoom.
