Izinto zensimbi ezingenasici 17-4PH

I-17-4PH ishushu ngokukhawuleza. Ngexesha lokunyanga ubushushu okanye ukubumba, i-atmospheres ekhuselayo equkethe i-carbon okanye i-nitrogen kufuneka igwenywe. Ezi zinto zinokufunxwa kwindawo yentsimbi kwaye zinike ulusu oluthambileyo lwe-austenitic. Ukuba umoya okhuselayo uyafuneka i-argon okanye i-helium iyacetyiswa.

I-alloy ikwanokuqina okulungileyo xa idityanisiwe, ngelixa unyango olufutshane lobushushu obuphantsi kweqondo lokushisa lunciphisa ukulwa kunye nokunyuka. Ukongeza, i-17-4PH ilula ukwenza umatshini kunye nokwenza.

Ndiyabulela kwiipropati ezinenzuzo, i-17-4PH ifumana ukusetyenziswa kumashishini ahlukeneyo. Amalungu aqhelekileyo abandakanya izitywini zoomatshini, iqhosha le-oyile, kunye ne-pump shafts.

I-Machinability 17-4PH inomatshini kuzo zombini isisombululo se-annealed condition kunye ne-precipitation lukhuni imeko. Ngenxa yokuba iqondo lokushisa lokugqibela lonyango lobushushu liphantsi, i-17-4PH inomatshini ukuya kwinqanaba lokugqibela kwimeko edibeneyo kwaye emva koko igugile ngaphandle kotshintsho olubalulekileyo lwe-dimensional okanye ukulinganisa ngaphandle kokuba icandelo likhulu, xa kufuneka kwenziwe isibonelelo sokunciphisa ukuguga.
Kwimeko ye-annealed machining yahluke nje kancinci ukusuka kwi-300 series austenitic stainless steels. Kwimeko ye-H900 isantya somatshini yi-60% yaloo nto yezinto ezifakwe emanzini.

Unyango lobushushu

I-Stainless Steel 17-4PH ifumaneka kwisicombululo se-annealed condition kwi-1900 °F (1038 °C) kwaye emva koko ipholile emoyeni ukuya kwi-90 °F (32 °C).

Nangona kunjalo, unyango olongezelelweyo lobushushu lunokuvelisa amanqanaba ahlukeneyo obunzima kunye nokuqina. Olona nyango luxhaphakileyo ludweliswe kwitheyibhile engezantsi.
