Fabrication thiab Thaum tshav kub kub kho
Machineability
Nrhiav cov cuab yeej los ntsuas koj cov hlau?
Qib 317 stainless hlau yog tawv dua li 304 stainless hlau.Nws raug nquahu kom siv chip breakers.Hardenability ntawm cov alloy no yuav raug txo yog tias cov khoom noj tas li thiab siv ceev ceev.
Vuam
Qib 317 stainless hlau tuaj yeem welded siv fusion thiab kuj txoj kev.Oxyacetylene vuam txoj kev tsis nyiam rau cov hlau no.AWS E/ER317 lossis 317L muab cov hlau tuaj yeem siv tau kom tau txais txiaj ntsig zoo.
Kub Ua Haujlwm
Qib 317 stainless hlau tuaj yeem ua haujlwm kub siv tag nrho cov txheej txheem ua haujlwm kub.Nws yog rhuab ntawm 1149-1260 ° C (2100-2300 ° F).Nws yuav tsum tsis txhob kub tshaj 927 ° C (1700 ° F).Tom qab ua haujlwm annealing tuaj yeem ua kom khaws cov khoom tiv thaiv corrosion.
Ua haujlwm txias
Stamping, shearing, drawing, thiab heading tuaj yeem ua tiav.Tom qab ua haujlwm annealing yog ua kom txo qis kev ntxhov siab sab hauv.
