Walxaha birta ah ee aan fiicnayn 17-4PH

17-4PH si fudud ayaa loo been abuurtay. Inta lagu jiro daawaynta kulaylka ama been-abuurka, jawiga difaaca ee ka kooban kaarboon ama nitrogen waa in laga fogaadaa. Waxyaabahaas waxaa lagu nuugi karaa dusha birta waxayna siinayaan maqaarka austenitic jilicsan. Haddii jawi ilaalin loo baahan yahay argon ama helium ayaa lagula talinayaa.

Daawadu waxa kale oo ay leedahay adayg wanaagsan marka la alxanayo, halka daawaynta kulaylka yar ee gaaban ay yaraynaysaa is-diridda iyo qolofta. Intaa waxaa dheer, 17-4PH way fududahay in la mariyo oo la sameeyo.

Thanks to sifooyinka faa'iidada leh, 17-4PH waxay helaysaa isticmaalka warshado kala duwan. Qaybaha caadiga ah waxaa ka mid ah shaabadihii farsamada, balastarka saliidda, iyo ulaha bamka.

Machinability 17-4PH waxaa lagu farsamayn karaa labadaba xalalka la tirtiray iyo xaalada adag ee roobabka. Sababtoo ah heerkulka daaweynta kulaylka kama dambaysta ah wuu hooseeyaa, 17-4PH waxaa lagu farsameyn karaa cabbirka ugu dambeeya ee xaaladda la tirtiray ka dibna da'da iyada oo aan isbeddelin cabbir weyn ama miisaan la'aan ilaa qaybtu ay weyn tahay, marka gunnada loo sameeyo foosha gabowga.
Xaaladda la tirtiray makiinadu wax yar bay ka duwan tahay 300 oo bir ah oo aan lahayn austenitic. Xaaladda H900 heerka makiinadu waa 60% ee walxaha la tirtiray.
