Ibyuma bitagira umwanda 17-4PH

17-4PH birashyushye byoroshye. Mugihe cyo kuvura ubushyuhe cyangwa guhimba, hagomba kwirindwa ikirere gikingira karubone cyangwa azote. Ibi bintu birashobora kwinjizwa mubyuma kandi bigatanga uruhu rworoshye rwa austenitis. Niba ikirere gikingira gisabwa argon cyangwa helium birasabwa.

Amavuta kandi afite ubukana bwiza iyo asuditswe, mugihe ubushyuhe buke bwo kuvura ubushyuhe bugabanya kugabanuka no gupima. Byongeye kandi, 17-4PH biroroshye gukora imashini no guhimba.

Bitewe nibintu byingirakamaro, 17-4PH isanga ikoreshwa mubikorwa bitandukanye. Ibice bisanzwe birimo kashe ya mashini, ibishishwa byamavuta, hamwe na pompe.

Imashini 17-4PH irashobora gutunganywa muburyo bwombi igisubizo hamwe nuburyo imvura igwa. Kuberako ubushyuhe bwa nyuma bwo kuvura ubushyuhe buri hasi, 17-4PH irashobora gutunganywa kugeza kurwego rwa nyuma muburyo bwa anneale hanyuma igasaza nta mpinduka nini igaragara cyangwa igipimo keretse niba igice ari kinini, mugihe hagomba gutangwa amafaranga yo kugabanya gusaza.
Muburyo bwa annealed imashini itandukanye gusa na 300 serie austenitike idafite ibyuma. Muburyo bwa H900 igipimo cyo gutunganya ni 60% yibyo bikoresho bifatika.
