Superior intergranular tsis kam

Tsawg -} cov roj carbon tsim: C Tsawg dua lossis sib npaug ntawm 0.03% tiv thaiv kev ua daus ntawm cov neeg muaj kev sib cav sib ceg

Hwj txwv: Tswj kev cuam tshuam corrosion tsis kam tom qab vuam, haum rau ntawm - Site Fabrication ntawm cov khoom siv tshuaj thiab cov raj xa dej.

 

 

Oxidation & Siab -} kub corrosion tsis kam

Hauv oxidation ib puag ncig tsawg dua los yog sib npaug nrog 500 degree, siab chromium (CR ≈23%) cov yeeb yaj kiab tuab oxide, thaiv cov pa oxygen. Cov ntawv thov suav nrog Flue Gas Desulfurization (FGD) chav nyob thiab kev hloov cua sov.

 

 

 

 

Corrosion Resistance sib piv (vs . 316 l, 645Smo)

Ntiag tug	904L	316L	645smo
Pren tus nqi	≈40	≈34	Ntau dua los yog sib npaug rau 50
Clj Scc Kuj	Zoo (tsawg dua los yog sib npaug rau 200 mg / l clr⁻)	Nruab nrab (tsawg dua los yog sib npaug rau 100 mg / l clr⁻)	Zoo heev (ntau dua lossis sib npaug nrog 400 mg / l clr⁻)
5% dilute hso₄ corrosion	0.2-0.5 mm / xyoo	0.5-1 mm / xyoo	<0.1 mm/year
Intergranular corrosion	Tsawg (qis - carbon)	Yog (xav tau cov stabilization)	Tsis muaj (tsawg {{- c, siab - n)
