Alloy Steel 904L cov pa roj carbon tsawg: corrosion tsis kam thiab cov yam ntxwv tseem ceeb

 

Ii. Cov tub ntxhais zoo ntawm corrosion tsis kam

1. Tshwj xeeb tsis kam mus rau chloride corrosion

Pitting & crevice corrosion tsis kam:
Nrog rau pitting tiv taus (pren) ntawm ~ 40 (pren=}}}}}} -} muaj cov xov xwm:

Saib xyuas cov yeeb yaj kiab ruaj khov hauv dej hiav txwv (cl ≈ ≈ 19,000 mg / l), brine, thiab chlorinated chemicals, tiv taus pitting tsim.

Qhov zoo tagnrho rau cov khoom siv dej hiav txwv, ntsev thiab cov roj av cov khoom siv ntau lawm, thiab chav ua yeeb yam.

Kev ntxhov siab corrosion cracking (SCC) tsis kam:
High Nickel cov ntsiab lus txhim kho kom clj -}} {l), tsawg dua lossis sib npaug tab sis me ntsis qis rau 645smo.

2. Bard tiv taus rau acidic media

Dilute Sulphruric & Phosphoric Acids:
Outperforms 316L hauv tsawg dua lossis sib npaug rau 5% sulfuric acid thiab tsawg dua los yog sib npaug rau 85% phosphoric acid, haum rau:

Sulfuric acid pickling cov khoom siv thiab cov tshuaj txaws hauv phosphate chiv.

Organic Acids & Cov Khoom Siv Ua Si:
Tolerates Organic acids (formic, acetic) thiab acidic media nrog trace clu aus (piv txwv li dav siv hauv kev ua zaub mov noj, cov chaw muag tshuaj, thiab tshuaj lom neeg hluavtaws.

Kev txwv:
Not resistant to concentrated nitric acid (>60% lossis hydrofluoric acid (HF), raws li siab -}}}}}}}}}}}} {{nrog cov khoom sib xyaws, nrawm corrosion.
