Cov txheej txheem Annealing Annealing AISI 302 suav nrog cov cua sov hlau mus rau qhov ntsuas kub thiab tom qab ntawd txias ntawm qhov qeeb heev thiab tswj tau. Annealing feem ntau yog siv rau:
soften ib qho hlau rau kev ua haujlwm txias
Txhim kho machinability
Txhim kho hluav taws xob conductivity
Annealing kuj restores ductility. Thaum lub sij hawm ua hauj lwm txias, cov hlau tuaj yeem ua rau tawv tawv kom muaj kev ua haujlwm ntxiv yuav ua rau tawg. Los ntawm annealing cov hlau ua ntej, kev ua haujlwm txias tuaj yeem tshwm sim yam tsis muaj kev pheej hmoo ntawm kev tawg, raws li annealing tso tawm txhua yam kev ntxhov siab uas tsim thaum lub sijhawm machining lossis sib tsoo.

Kev cuam tshuam ntawm 18-8 austenitic stainless hlau rau qhov kub thiab txias hauv 800 degree F txog 1500 degree F (427 degree txog 816 degree) ntau yam yuav ua rau nag lossis daus ntawm chromium carbides hauv cov ciam teb. Cov hlau zoo li no yog "sensitized" thiab raug cuam tshuam rau intergranular corrosion thaum raug rau ib puag ncig hnyav. Cov ntsiab lus carbon ntawm Hom 302, 304 thiab 305 tuaj yeem tso cai rau qhov kev xav tau tshwm sim los ntawm cov cua sov uas tau ntsib los ntawm autogenous welds yog cov tshav kub cuam tshuam ntawm welds. Vim li no, cov pa roj carbon tsawg 304L alloy yog nyiam rau cov ntawv thov uas cov khoom raug muab tso rau hauv kev pabcuam hauv cov xwm txheej zoo li-welded. Cov ntsiab lus tsis tshua muaj carbon txuas ntxiv lub sijhawm tsim nyog los ua kom muaj kev phom sij ntawm chromium carbides, tab sis tsis tshem tawm cov nag lossis daus cov khoom siv rau lub sijhawm ntev hauv nag lossis daus.
