302 Stainless Hlau Phaj

302 stainless hlau ntawv yog austenitic stainless hlau, uas muaj corrosion kuj zoo, kub tsis kam, tsis kub kub lub zog thiab txhua yam khoom. Kub kub ua haujlwm zoo rau stamping thiab dabtsi yog khoov, tsis muaj cua sov kho hardening.

Alloy sawv cev rau kev sib xyaw ua ke zoo heev ntawm corrosion kuj thiab fabricability. Cov neeg siv yav dhau los ntawm 302 stainless feem ntau tam sim no siv 304 alloy txij li AOD thev naus laus zis tau ua kom qis cov pa roj carbon ntau yooj yim dua thiab pheej yig dua.

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.
