321 stainless hlau ntawv phaj kuj yog qhov zoo rau kev pabcuam kub kub vim nws cov khoom siv zoo. Alloy 321 stainless hlau phaj muaj ntau dua creep thiab kev nyuaj siab rupture zog tshaj Alloy 304 thiab, tshwj xeeb tshaj yog, Alloy 304L, uas tej zaum kuj yuav raug txiav txim siab rau exposures qhov twg rhiab heev thiab intergranular corrosion yog kev txhawj xeeb.

SS 321 phaj yog cov pa roj carbon ntau dua (0.04 - 0.10) version ntawm cov hlau. Nws yog tsim los txhim kho creep tsis kam thiab rau siab zog ntawm qhov kub siab tshaj 1000oF (537 degree). Feem ntau, cov pa roj carbon ntsiab lus ntawm lub phaj ua kom muaj kev pov thawj dual.Alloy 321 stainless hlau phaj tsis tuaj yeem ua kom tawv los ntawm kev kho cua sov, tsuas yog ua haujlwm txias. Nws tuaj yeem ua tau yooj yim welded thiab ua tiav los ntawm cov txheej txheem khw fabrication.
