S321 vs 254smo corrosion tsis kam
S31254 Surpasses S321 nyob ze li ntawm txhua qhov kev ua tau zoo ntawm corrosion (tshwj xeeb yog pitting, corrosion corrosion, chloride ion tsis kam, thiab scc). S321 tus nqi tseem ceeb nyob hauv nws txoj kev tiv thaiv hauv kev txhim kho hauv kev txhim kho corrosion tom qab vuam lossis qib kub. Qhov txiaj ntsig zoo tshaj 304 hauv qee qhov kev ua haujlwm (tsis-chloride ib puag ncig) tsis them rau nws qhov tsis muaj zog hauv chloride-muaj chaw ib puag ncig.
| Ntiag tug | S31254 | S321 |
|---|---|---|
| Pitting / crevice corrosion (CLR) | Zoo heev (resistays seawater / High-clj) | Pluag (Zam chloride ib puag ncig) |
| Intergranular corrosion | Zoo heev (ultra-qis c txwv tsis pub cov rhiab) | Zoo heev (Ti stabilization tiv thaiv cov rhiab) |
| Kev ntxhov siab corrosion cracking (SCC) | Zoo (resistions cliv scc hauv qab 60 degree) | Poor (High risk in Cl⁻ >60 degree) |
| General Corrosion | Muaj Koj Zoo (Tsis kam tawm muaj zog acids / txo cov xov xwm) | Nruab Nrab (haum rau oxidizing media tsuas yog) |
Stainless Hlau 1.4547 vs 1.4541 Txhua Yam & Lub Zog
S31254 tau muaj lub zog dua siab dua, uas tuaj yeem tso cai rau cov phab ntsa thickness nyob hauv cov yeeb nkab tsim (kev ua kom muaj kev ua haujlwm hnyav dua, ua haujlwm txias dua. Cov cuab yeej siv cov khoom siv ntawm S321 yog los ze zog rau cov pa taws 304.

S31254 Hlau Vs S32100 Vuam
Cov txheej txheem vuam rau S321 kuj kuj yooj yim thiab muaj kev ua kom muaj ntau dua. VUAM S31254 xav tau ntau cov txheej txheem tshwj xeeb, cov kev tawm tsam me me, tsis tshua muaj kub vuam cov nuj nqis thiab kev xav tau nyob rau hauv cov kev xav tau. Txawm li cas los xij, nws cov post-weld corrosion tsis kam (ob leeg nyob rau hauv weld thiab haz) nyob deb tshaj ntawm S321 hauv kev hnyav ib puag ncig.
