Machining stainless hlau qib 317L yuav tsum muaj kev ceev qis thiab cov khoom noj tas li kom txo tau nws txoj kev ua haujlwm nyuaj.Cov hlau no tawv dua li qib 304 stainless hlau nrog cov hlua ntev ntev;Txawm li cas los xij, kev siv chip breakers raug pom zoo.Vuam tuaj yeem ua tau los ntawm kev siv feem ntau ntawm cov pa fusion thiab kev tiv thaiv.Oxyacetylene vuam yuav tsum zam.AWS E/ER 317L 317L filler metal is recommend.
Cov txheej txheem kub ua haujlwm tuaj yeem ua tau.Cov khoom yuav tsum tau rhuab mus rau 1149-1260 ° C (2100-2300 ° F);Txawm li cas los xij, nws yuav tsum tsis txhob kub qis dua 927 ° C (1700 ° F).Txhawm rau txhim kho corrosion kuj, kev ua haujlwm tom qab annealing yog pom zoo.
Shearing, stamping, taub hau thiab kos duab yog ua tau nrog qib 317L stainless hlau, thiab tom qab ua haujlwm annealing raug pom zoo kom tshem tawm cov kev ntxhov siab sab hauv.Annealing yog ua nyob rau ntawm 1010-1121 ° C (1850-2050 ° F), uas yuav tsum tau ua raws li los ntawm kev txias ceev.
Qib 317L stainless hlau tsis teb rau kev kho cua sov.
