AISI/SUS 309 STAINLESS STEEL COIL/SHEET

Stainless hlau yog cov hlau alloy siab uas muaj kev tiv thaiv corrosion ntau dua piv rau lwm cov hlau vim tias muaj cov chromium ntau. Raws li lawv cov qauv crystalline, lawv tau muab faib ua ferritic, austenitic, thiab martensitic steels.

Qib 309 stainless hlau muaj siab corrosion kuj thiab lub zog piv rau 304 stainless hlau. Cov ntaub ntawv hauv qab no muab cov ntsiab lus ntawm qib 309 stainless hlau.

General Properties

Alloy 309 (UNS S30900) yog austenitic stainless hlau tsim los siv rau hauv cov ntawv thov kub kub corrosion. Cov hlau tiv taus oxidation txog 1900 ° F (1038 ° C) nyob rau hauv cov xwm txheej tsis-cyclic. Kev caij tsheb kauj vab ntau zaus txo oxidation tsis kam mus rau kwv yees li 1850 ° F (1010 ° C).

Vim tias nws cov chromium siab thiab cov ntsiab lus tsis tshua muaj npib tsib xee, Alloy 309 tuaj yeem siv rau hauv sulfur uas muaj cua sov txog 1832 ° F (1000 ° C). 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 ° C) cov hlau yog raug rau sigma theem nag lossis daus. Ib qho tshuaj annealing kev kho mob ntawm 2012 - 2102 ° F (1100 - 1150 ° C) yuav rov ua kom tawv nqaij.

309S (UNS S30908) yog qhov qis carbon version ntawm cov hlau. Nws yog siv rau kev yooj yim ntawm fabrication. 309H (UNS S30909) yog ib qho kev hloov kho 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.

Alloy 309 tuaj yeem ua tau yooj yim welded thiab ua tiav los ntawm cov txheej txheem khw tsim khoom.
