446 yog lub siab chromium ferritic tshav kub resistant alloy nrog zoo heev tiv thaiv oxidation, sulfidation thiab lwm yam kub corrosion. Qib no feem ntau yog siv nyob nruab nrab ntawm 1500 - 2100 degree F, txawm hais tias nws qhov kub thiab txias zog yog tsawg heev. 446 yog tib lub tshav kub-resistant alloy uas yuav zam molten tooj liab thiab tooj dag. Raws li nrog rau lwm cov high chromium ferritic stainless, 446 embrittlement hnyav nyob rau hauv lub 700-1000 degree F kub ntau (885 degree F embrittlement). 446 yuav tsum tsis txhob siv nyob rau hauv qhov kub thiab txias no tshwj tsis yog tias yuav luag tag ntawm chav tsev kub ductility yuav raug zam. Sigma theem embrittlement tshwm sim thaum lub sij hawm ntev raug nyob rau hauv 1000-1300 degree F ntau.

GENERAL PROPERTIES
Qib 446 stainless hlau yog ferritic, uas tsis yog-kub kho tau stainless hlau uas muab kev tiv thaiv zoo rau kub oxidation thiab corrosion. Cov ntaub ntawv hauv qab no muab cov ntsiab lus ntxiv ntawm qib 446 stainless hlau.

WELDING
Qib 446 stainless hlau tuaj yeem yooj yim welded siv feem ntau ntawm cov txheej txheem ib txwm tsuas yog oxyacetylene vuam. Hom 308 vuam cov khoom siv tau yog tias xav tau, tab sis nws yuav tsis pom qhov ntsuas qhov sib npaug ntawm cov hlau puag. Qhov sib txawv ntawm coefficient ntawm thermal expansion ntawm lub hauv paus thiab weld hlau yuav tsum tau muab coj los xav.
