High purity ferrite

Cov hlau no muaj cov pa roj carbon tsawg heev, nitrogen; siab chromium, molybdenum, titanium, niobium thiab lwm yam ntsiab lus. Xws li Tuam Tshoj' s 00Cr17Mo, 00Cr18Mo2, 00Cr26Mol, 00Cr30Mo2 thiab txawv teb chaws 18-2, Cr26Mol, 25Cr-5Ni-4Mo-Nb, MoNiT, Al29-4, Al29-4-2. Cov hom hlau no muaj cov khoom siv kho tshuab zoo (tshwj xeeb yog cov tawv zoo), weldability, intergranular corrosion tsis kam, pitting corrosion tsis kam, crevice corrosion tsis kam, thiab zoo heev kev nyuaj siab corrosion cracking kuj. Piv txwv, 18-2 muaj cov tshuaj tiv thaiv zoo hauv nitric acid, acetic acid, thiab NaOH. Qhov pitting corrosion tsis kam hauv 3% NaCl thiab FeCl3 yog qhov sib npaug lossis ntau dua 18-8 austenitic steel, thiab SCC tsis kam mus deb tshaj 18-8 steel. 26CrMo steel muaj peev xwm tiv taus xeb hauv ntau cov xov xwm, tshwj xeeb tshaj yog cov organic acids, oxidizing acids, thiab muaj zog alkalis. Nws muaj zoo pitting tsis kam nyob rau hauv muaj zog chloride nruab nrab. Tsis muaj kev ntxhov siab vim yog xeb hauv chloride, hydrogen sulfide, ntau heev sulfuric acid thiab muaj zog alkali. 30Cr-2Mo muaj qhov muaj peev xwm tiv taus ntau dua rau pitting thiab crevice corrosion thaum tswj kev nyuaj siab corrosion kuj. Hlau nrog me me ntawm nickel tuaj yeem txhim kho nws qhov kev ua tau zoo hauv kev txo cov kua qaub.
