S304 thiab S316 xa mus rau ob ntawm cov qib feem ntau ntawm austeniticstainless hlau, feem ntau txawv los ntawm lawv cov tshuaj muaj pes tsawg leeg thiab corrosion kuj. Qhov sib txawv tseem ceeb yog qhov sib ntxiv ntawmmolybdenumnyob rau hauv S316, uas muab superior tsis kam rau chlorides thiab acids.
Qhov txawv tseem ceeb

| S304 Stainless hlau | S316 Stainless hlau | |
|---|---|---|
| Chemical Comp. | ~ 18% Chromium, ~ 8% Nickel, taug qab Molybdenum | ~ 16% Chromium, ~ 10% Nickel, 2-3% Molybdenum |
| Corrosion Resistance | Zoo dav tsis kam rau oxidation thiab ntau yam tshuaj | Superior kuj, tshwj xeeb tshaj yog rau chlorides, ntsev, thiab muaj zog acids |
| Nqi | Feem ntau tsis tshua kim | kim dua vim molybdenum thiab ntau dua nickel cov ntsiab lus |
| Daim ntawv thov | Cov khoom siv hauv tsev, khoom noj khoom haus, kev siv dav dav, kev tsim vaj tsev sab hauv, cov khoom siv tsheb | Cov cuab yeej siv dej hiav txwv thiab ntug hiav txwv, cov chaw ua tshuaj lom neeg, cov khoom siv kho mob, siab -cov dej ntsev |
| Magnetic Properties | Tsis yog- sib nqus (txawm tias txias- ua haujlwm tuaj yeem ua rau me me hlau nplaum) | Tsis yog-magnetic |
Cov ntsiab lus
S304 (Hom 304)yog ntau yam thiab dav siv stainless hlau, muab qhov zoo sib npaug ntawm lub zog, formability, thiab corrosion kuj rau kev siv, niaj hnub siv.
S316 (Hom 316)yog qib siab dua - cov khoom siv qib siab tsim los rau qhov chaw xav tau ntau dua. Qhov sib ntxiv ntawm molybdenum ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas cuam tshuam ncaj qha nrog cov dej ntsev, cov tshuaj brine, lossis cov tshuaj hnyav uas pitting thiab crevice corrosion muaj kev txhawj xeeb.
