Fabrication thiab Thaum tshav kub kub kho
Machineability
Qib 310S stainless hlau tuaj yeem ua tau zoo ib yam li qib 304 stainless hlau.
Vuam
Qib 310S stainless hlau tuaj yeem welded siv fusion lossis tsis kam vuam cov txheej txheem.Oxyacetylene welding txoj kev tsis nyiam rau vuam no alloy.
Kub Ua Haujlwm
Qib 310S stainless hlau tuaj yeem ua haujlwm kub tom qab cua sov ntawm 1177°C (2150°F).Nws yuav tsum tsis txhob forged hauv qab 982°C (1800°F).Nws yog txias ceev kom ua rau corrosion kuj.
Ua haujlwm txias
Qib 310S stainless hlau tuaj yeem ua tau taub hau, chim siab, kos, thiab stamped txawm tias nws muaj kev ua haujlwm siab zog.Annealing yog ua tom qab ua haujlwm txias kom txo qis kev ntxhov siab sab hauv.
Annealing
Qib 310S stainless hlau yog annealed ntawm 1038-1121°C (1900-2050°F) tom qab ntawd quenching hauv dej.
Hardening
Qib 310S stainless hlau tsis hnov mob rau kev kho cua sov.Lub zog thiab hardness ntawm cov hlau no tuaj yeem nce los ntawm kev ua haujlwm txias.
