SUS 309 / 309S (UNS S30900 / S30908) austenitic stainless hlau feem ntau yog siv rau kev siv kub siab. Nws cov ntsiab lus siab chromium thiab npib tsib xee muab piv rau corrosion kuj, superior tiv thaiv oxidation, thiab khaws cia ntawm ib feem loj ntawm chav tsev kub lub zog tshaj cov hom austenitic Alloy 304.

General Properties
Alloy 309 (UNS S30900) yog austenitic stainless hlau tsim los siv rau hauv cov ntawv thov kub kub corrosion. Lub alloy tiv taus oxidation mus txog 1900℃F (1038 degree) nyob rau hauv tsis yog - tej yam kev mob. Nquag thermal cycling txo oxidation tsis kam mus txog 1850℃F (1010℃).
Vim tias nws cov chromium siab thiab cov ntsiab lus tsis tshua muaj npib tsib xee, SUS 309 tuaj yeem siv rau hauv sulfur uas muaj cua sov txog 1832℃F (1000 degree). Cov hlau tsis pom zoo siv rau hauv cov huab cua uas muaj carburizing heev vim nws tsuas yog ua kom tsis zoo rau cov pa roj carbon nqus. Alloy 309 tuaj yeem siv rau hauv me ntsis oxidizing, nitriding, cementing thiab thermal cycling daim ntaub ntawv, txawm hais tias, qhov siab tshaj plaws kev pabcuam kub yuav tsum raug txo.
Thaum rhuab ntawm 1202 - 1742℃F (650 - 950 degree) cov hlau yog raug rau sigma theem nag lossis daus. Ib qho kev daws teeb meem kev kho mob ntawm 2012 - 2102℃F (1100 - 1150 degree) yuav rov ua kom muaj zog dua.
SUS309S (UNS S30908) yog qhov qis carbon version ntawm cov hlau. Nws yog siv rau kev yooj yim ntawm fabrication. SUS309H (UNS S30909) yog ib qho kev hloov pauv carbon siab tsim los txhim kho kev nkag siab zoo. Nws feem ntau piv txwv li cov nplej loj thiab cov ntsiab lus carbon ntawm lub phaj tuaj yeem ua tau raws li 309S thiab 309H cov cai.
FAQ
Q. Kuv puas tuaj yeem muaj cov qauv txiav txim rau cov khoom siv stainless hlau phaj?
