Alloy 309 thiab 309s yog cov paub zoo tshaj plaws rau kev kub siab kub. Qhov no alloy ua haujlwm tau zoo txog 2000 degree f, tshwj xeeb yog yog oxidation tsis kam. 309 thiab 310 Stainless hlau yog thawj cov neeg kub siab tshaj plaws ntawm cov qib tsis zoo ntawm peb cov khoom lag luam. High Nickel thiab Chromium Cov Ntsiab Lus thiab Cov Qauv Couge Cov Qauv Ua Rau:
Txhim kho tsis kam mus rau cyclic oxidation
Ua kom muaj zog tiv thaiv sulfidation
Zoo dua kub siab zog
Txhim kho tiv taus rau intergranular corrosion
309s (unt s30908) stainless hlau yog cov carbon version tsawg ntawm cov alloy. Nws yog siv rau yooj yim ntawm cov fabrication.
309H (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. Thaum rhuab ntawm 1202 - 1742 degree F (650 - 950 degree) cov hlau yog raug rau sigma theem nag lossis daus. Ib qho kev daws teeb meem annealing ntawm 2012 - 2102 degree F (1100 - 1150 degree) yuav rov ua kom muaj zog dua. Alloy 309 tuaj yeem ua tau yooj yim welded thiab ua tiav los ntawm cov txheej txheem khw tsim khoom.
Daim ntawv thov
Alloy 309 thiab Alloy 309s yog kub tiv thaiv ntau yam ntawm stainless hlau siv hauv kev kub kub kev pabcuam kub. Koj tuaj yeem nrhiav 309 thiab 309s steel yeeb nkab thiab cov thawv hluav taws, hlawv cov thawv, cov roj kub, pob zeb thiab khoom siv sulfite.
