Daim ntawv no siv rau cov hlau stainless 904L / 1.4539 kub thiab hle cov hlau thiab cov khoom siv sib khi thiab welded rau lub hom phiaj siab.
Daim ntawv thov
Cov nroj tsuag tshuaj, roj refinery, petrochemical nroj tsuag, bleaching tank rau daim ntawv kev lag luam, combustion gas desulfurisation nroj tsuag, thov nyob rau hauv dej hiav txwv, sulfuric thiab phosphoric acid. Vim yog C-cov ntsiab lus tsawg, qhov kev tiv thaiv rau intergranular corrosion kuj tau lees tias nyob rau hauv cov xwm txheej welded.
