Stainless hlau 1.4462

1.4462 duplex stainless hlau phaj muaj corrosion kuj zoo heev thiab tuaj yeem tiv taus qhov yaig ntawm ntau yam corrosive media. Nws tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev txawm tias nyob hauv qhov chaw nyuaj thiab hnyav. Nws cov qauv duplex tshwj xeeb muab nws lub zog siab thiab zoo toughness, ua rau nws tuaj yeem tiv taus sab nraud loj thiab cuam tshuam, ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov qauv.
1.4462 stainless hlau phaj kuj muaj kev ua haujlwm zoo vuam, thiab tsis ua rau cov kab nrib pleb thiab lwm yam teeb meem thaum lub sij hawm vuam, kom ntseeg tau qhov zoo thiab tag nrho kev ua tau zoo ntawm vuam qhov chaw. Nyob rau tib lub sijhawm, nws cov kev ua haujlwm kub ua haujlwm kuj zoo heev, uas yooj yim rau kev ua thiab kev tsim khoom ntawm ntau yam duab thiab specifications.

1.4462 Khoom siv thaum tshav kub kub kho:
1.4462 stainless hlau daim hlau yuav muab tshuaj annealed ntawm qhov tsawg kawg nkaus ntawm 1900 degree F thiab ces txias sai, nyiam siv dej quenching. Qhov kev kho no haum rau kev daws annealing thiab kev ntxhov siab. Yuav tsum tsis muaj kev kho kev ntxhov siab lossis kev pom zoo; Tab sis yog tias tsim nyog, cov khoom siv yuav tsum tau ua kom tiav cov tshuaj annealing saum 1900 degree F, ua raws li cov cua txias los yog dej quenching.
