2205 vs 2507 Duplex Stainless Steels: Standard vs Super Duplex Performance

 

Dab tsi yog lawv cov ntsiab lus tseem ceeb thiab kev ua haujlwm sib txawv?

2205 muaj 21–23% Cr, 4.5–6.5% Ni, 2.5–3.5% Mo, 0.08–0.20% N-yield zog ≥450MPa, PREN ~ 33 (resist seawater).2507 nta 24–26% Cr, 6–8% Ni% 0.24–0.32% N-yield zog ≥550MPa, PREN ~ 42 (kuav kub brines).Ob lub zog yog ob zaug li 316L, txo cov khoom thickness.

Yuav ua li cas lawv cov corrosion kuj ua tau nyob rau hauv huab chaw?

2205 haum rau cov khoom siv hluav taws xob hauv ntug dej hiav txwv (≤50 ° C dej hiav txwv).

Nyob rau hauv daim ntawv thov twg yog ib qib irreplaceable?

Xaiv 2205 rau tus qauv hnyav ib puag ncig (tus nqi- siv tau rau tsis yog- cov kev xav tau duplex heev).Kev xaiv 2507 rau ultra-cov tshuaj chloride hnyav / qaub qaub-2205 tsis ua haujlwm hauv cov chaw no.

Tus nqi thiab kev tsim khoom lag luam yog dab tsi- tawm?

2507 tus nqi 30-50% ntau tshaj 2205, yog li nws tsuas yog siv rau cov huab cua puag ncig.2205 tiv taus siab dua vuam cua sov input; 2507 xav tau kev nruj qis -kub tswj kom khaws ferrite- austenite tshuav nyiaj li cas.

Cov txheej txheem tseem ceeb yog dab tsi?

Zam ob qib nyob rau hauv ib puag ncig muaj kua qaub- hloov mus rau 904L.Prioritize 2205 rau cov qauv hnyav; xaiv 2507 rau ultra-siab-siab, siab -temp chloride kev pabcuam.
