1.440 vs. Sus316 Stainless hlau: Corrosion Resistance sib piv
Intergranular corrosion tsis kam:
1.4404 (316L) muaj qhov zoo dua tsis kam kam rau nws cov pa roj carromium, txawm tias yuav ua rau muaj kev chim siab tshiab, txawm tias tom qab siv sij hawm ntev (400-800 degree).
General corrosion tsis kam:
Ob qho tib si tiv thaiv cov organic acids, cov kua dej ntsev, thiab dej hiav txwv, ua rau lawv haum rau tshuaj, cov tub rog, khoom noj khoom haus, thiab khoom lag luam. Txawm li cas los xij, 1.4404 yog cov kev ntseeg tau ntau hauv welded lossis cov ntawv thov kub siab.
1.440 vs. Sus316 Stainless hlau: Daim Ntawv Thov
1.4404 (316L)yog qhov zoo tagnrho rau:
Welded Cheebtsam (piv txwv, cov tshuaj tiv thaiv tshuaj lom neeg, cov twj tso kua mis)
Corrosive ib puag ncig nrog kub
Dej hiav txwv hoses systems
Cov khoom noj ua khoom noj (qhov twg residual kev ntxhov siab-ua rau corrosion yuav tsum zam)
Sus316 (316)yog tsim nyog rau:
Cov kws ua kom muaj zog corrosive (piv txwv li, tshuab zas tshuab, kho cov khoom siv)
Tsis-welded qauv los yog cov khoom siv uas tuaj yeem ua tau annealed tom qab vuam
Tus nqi them tus nqi (cov nqi pheej yig dua 316L)
Xaus: Yuav ua li cas xaiv?
Xaiv 1.4404 (316L)Yog tias koj daim ntawv thov cuam tshuam nrog vuam, ntev ntev-kub raug, lossis siab rhiab rau intergranular rau intergranular corrosion (piv txwv li, kev tawm tsam lossis sab nrauv.
Xaiv Sus316 (316)Yog tias tus qauv tsis yog welded, tuaj yeem ua tau annealed tom qab Weld, lossis yog tias koj xav tau txo cov nqi khoom hauv ib puag ncig muaj me ntsis.
