daim ntawv thov
Nyob rau hauv kev tsim cov urea 03H17N14MZ alloy siv rau hauv ob sab phlu ntawm cov synthesis kem thiab mixers, thiab nyob rau hauv lub tsim ntawm caprolactam - cyclohexane oxidation reactors. Cov hlau no yog siv rau hauv kev tsim cov qauv welded, uas ua haujlwm hauv sulphate media, nrog rau hauv boiling 10% acetic thiab phosphoric acids.
Kev kho mob
Yas kub deformation yog nqa tawm nyob rau hauv qhov kub ntawm 1150-900 degree C. Cov hlau no muaj siab plasticity. Dej quenching ntawm 1080 ± 20 ° C yog siv los txo kev ua hauj lwm hardening thiab tom qab txias-kub yas deformation.
Vuam
Zoo weldability ntawm txhua hom tsis siv neeg thiab phau ntawv vuam. Thaum siv hluav taws xob tes vuam siv electrodes RLA-20 nrog steel hlau 03H17N14M2 (los yog EP551). Nyob rau hauv tus txheej txheem ntawm tsis siv neeg vuam nyob rau hauv inert roj los yog submerged arc hlau siv tib hom. Lub zog thiab corrosion kuj ntawm welded pob qij txha thaum tsis qis dua lub hauv paus hlau. Welds steel urea synthesis nyob rau hauv nruab nrab tsis cuam tshuam rau intergranular, corrosion, thiab cov hniav muaj 0,041-0,11 corrosion tus nqi mm / xyoo.
Cim npe nrov: 03h17n14m3- 1.
