Tsis zoo li cov tsoos 300-series stainless steels, uas yog purely austenitic, los yog 400-series xaiv, uas yog purely ferritic,UNS S31803cais qhov sib txawv. Nws tuav qhov kwv yees50:50 piv ntawm austenite thiab ferrite.
- Yield Strength Amplification:Cov ferritic tivthaiv tso cai rau S31803 cov kav dej xa tawm qhov tsawg kawg nkaus lub zog ntawm 450 MPa ($ 65\\text{ ksi}$). Qhov no yog kwv yees li ob npaug ntawm lub zog tawm los ntawm cov khoom siv austenitic xws li 316L. Cov kws tshaj lij tuaj yeem siv lub zog ntxiv no rau spec thinner phab ntsa profiles, txo qis tag nrho cov qauv hnyav yam tsis muaj kev cuam tshuam kev nyab xeeb.
- Stress Corrosion Cracking (SCC) Kev Tiv Thaiv:Standard austenitic steels tsis tu ncua vim muaj cov tshuaj chloride hauv zos -induced stress corrosion cracking nyob rau hauv kub, saline ib puag ncig. Lub ferritic network nyob rau hauv S31803 cuam tshuam cov kev puas tsuaj ntawm cov kab mob no, ua rau cov yeeb nkab tiv taus cov neeg kho tshuab tsis ua hauj lwm hauv cheeb tsam hnyav chloride.

Seamless S31803 Cov kav dej
Tsim los ntawm kub extrusion los yog txias kos duab ntawm cov khoom billets, seamless xaiv tsis muaj weld seams los yog cua sov-ffect zones (HAZ).
Qhov zoo tshaj plaws rau:Ultra-siab-siab hydraulic systems, gas processing kab, thiab tseem ceeb tshuaj tuav qhov twg xoom geometric anomalies yuav tsum tau.
Qhov zoo:Tshem tawm txhua qhov kev pheej hmoo ntawm kev tsis sib haum xeeb hauv cheeb tsam lossis kev sib cais ntawm alloy uas tuaj yeem tshwm sim qee zaus thaum cov txheej txheem welding.
Welded & EFW S31803 Pipes
Ua los ntawm cov hlau nplaum los yog phaj, cov no tau koom nrog kev siv cov roj tungsten arc vuam (GTAW) lossis cov txheej txheem plasma arc vuam (PAW), feem ntau tswj hwm los ntawm tus qauv.ASTM A928 Cov Lus Qhia Tshwj Xeebspecifications.
Qhov zoo tshaj plaws rau:Loj - txoj kab uas hla hla - lub teb chaws thauj dej, cov txheej txheem marine pilings, thiab qis - cov tshuab nqus tsev siab.
Qhov zoo:Muab cov phab ntsa tuab tuab heev thoob plaws cov txheej txheem dav dav, muab tus nqi - siv tau zoo rau cov kav dej loj dua.

Technical Specifications: S31803 vs S32205
Ntau tus tswv teb nug txog qhov sib txawv ntawm cov neeg lausUNS S31803npe thiab tus tshiabUNS S32205qib.
Keeb kwm, S31803 chemistry specification tau sau nrog cov kev txwv dav dav. Txhawm rau ua kom muaj kev txhim kho corrosion, cov mills niaj hnub no tau txwv kev tsim khoom mus rau sab sauv kawg ntawm S31803 qhov rais - tshwj xeeb yog tsom rau qib siab ntawm chromium, molybdenum, thiab nitrogen.
Qhov kev ua tau zoo no - hloov pauv tau ua raws li tus qauvUNS S32205.
Niaj hnub no, cov khoom siv niaj hnub no feem ntau yog ob daim ntawv pov thawj raws li S31803 thiab S32205, ua tiav cov txheej txheem thiab tshuaj lom neeg ntawm ob qho tib si qauv.
