Machineability
Machining qib 347H stainless hlau yog me ntsis tawv dua li ntawm qib 304 steel.Txawm li cas los xij, qhov hardenability ntawm cov hlau no tuaj yeem txo qis los ntawm kev siv cov khoom noj zoo tas li thiab qeeb qeeb.
Vuam
Qib 347H stainless hlau tuaj yeem welded siv feem ntau ntawm kev tiv thaiv thiab fusion txoj kev.Oxyacetylene welding tsis nyiam rau cov hlau no.
Kub Ua Haujlwm
Forging, chim siab thiab lwm yam txheej txheem ua haujlwm kub tuaj yeem ua tau ntawm 1149 txog 1232 ° C (2100 txog 2250 ° F).Qib 347H hlau yuav tsum tau dej quenched thiab annealed kom tau qhov siab tshaj plaws hardness.
Ua haujlwm txias
Qib 347H stainless hlau tuaj yeem nkag tau yooj yim stamped, blanked, spun thiab kos vim nws yog tawv heev thiab ductile.
Annealing
Qib 347H stainless hlau tuaj yeem muab tso rau ntawm qhov kub ntawm 1010 txog 1193 ° C (1850 txog 2000 ° F) thiab tom qab ntawd quenched nrog dej.
Hardening
Qib 347H stainless hlau tsis teb rau kev kho cua sov.Lub hardness thiab lub zog ntawm cov hlau tuaj yeem nce los ntawm kev ua haujlwm txias.
