347h Stainless hlau yeeb nkab vs .316 l stainless hlau yeeb nkab hlau: Yuav Ua Li Cas Xaiv
Cov xwm txheej rau xaiv 347h:
High temperature environment (>550 degree): xws li hwj huam tsob nroj boilers, hnub ci thermal zog ntau tiam.
Qhov chaw uas tsis tuaj yeem kho cua sov tom qab vuam: vam khom Niobium ruaj khov kom tsis txhob intergranular corrosion .
Sulfide corrosion: xws li refinery hydrogenation units .
Cov xwm txheej rau kev xaiv 316L:
Chloride ib puag ncig: xws li cov marine engineering, cov khoom siv tshuaj lom neeg .
Nquag vuam thiab tsis muaj cov mob tom qab ua: ultra-tsis muaj cov pa roj carbon tsawg dua txo cov kev pheej hmoo txaus ntshai.
General corrosion-resistant qauv uas raug nqi-rhiab: xws li zaub mov machinery thiab khoom siv kho mob.
