Thepa e sa hloekang 17-4 PH e khetholloa ke matla a mangata a lihlahisoa, ho hanyetsa ha kutu e ntle le ho hanyetsa ho apara ho phahameng. 17-4 PH ke e 'ngoe ea litšepe tsa bohlokoa ka ho fetisisa tse ka thatafatsoang. Hoa tšoana ka tlhahlobo le lisebelisoa tsa 1.4548 le 1.4542.

Tšebeliso ea mocheso o tlase oa mocheso o ka khoneha ka Condition H1150 le H1025. Matla a ts'usumetso a matla a notched a boetse a fanoa ka mocheso o tlase.

Ka lebaka la thepa e ntle ea mochini le ho hanyetsa ho bola, thepa e loketse ho sebelisoa libakeng tsa leoatle, empa e kotsing ea ho bola ha metsi a leoatle a emeng.

17-4PH e tsebahala haholo e le AISI 630.

Thepa ea 17-4PH e sebelisoa indastering ea lik'hemik'hale, indasteri ea lehong, indasteri ea maoatle, kahong ea likepe, boenjiniere ba mechine, indastering ea oli, indastering ea pampiri, indastering ea lipapali. Indasteri ea boikhathollo hape e le mofuta o qhibilihisitsoeng hape (ESU) moeeng le Aerospace.

Haeba thepa ea mochini le ho hanyetsa kutu ea litšepe tsa martensitic li sa lekana, 17-4PH e ka sebelisoa.

Thepa e le 'ngoe e khethehileng ea thepa ea 17-4 PH ke ho tšoaneleha bakeng sa mocheso o tlase le ho sebetsa ho fihlela hoo e ka bang. 315°C.
Ho qapa:Ho etsoa ha thepa ho etsahala ka mocheso oa mocheso oa 1180 ° C ho ea ho 950 ° C. Ho etsa bonnete ba ho hloekisa lijo-thollo, ho pholisa ho mocheso oa kamore ho etsoa ka moea.
Welding:Pele thepa ea 17-4 PH e ka chesoa, ho lokela ho nahanoa ka boemo ba thepa ea motheo. Ka mokhoa o tsitsitseng, koporo e teng ka boitsebiso. Sena ha se khothaletse ho phatloha ho chesang.

Ho khona ho etsa welding optimum tjheseletsa maemo a hlokahala. Li-undercuts kapa liphoso tsa welding li ka lebisa ho thehoeng ha notch. Seo se lokela ho qojoa. Ho thibela ho thehoa ha mapetsong a khatello ea kelello, thepa e tlameha ho ba tlas'a tharollo ea annealing le botsofali bo latelang ka nako e khutšoanyane haholo ka mor'a ho cheselletsa.

Haeba ho se na phekolo ea ka mor'a mocheso, litekanyetso tsa mochine-theknoloji ka har'a seam weld le sebaka se amehileng ke mocheso ho thepa ea motheo e ka fapana haholo.

Corrosion resistance:ha thepa ea mechine le ho hanyetsa kutu ea litšepe tsa martensitic li sa lekana, 17-4 PH e loketse ho sebelisoa libakeng tsa leoatle. E na le motsoako oa thepa e ntle haholo ea mochine le ho hanyetsa ho bola.

Metsing a emeng a leoatle, 17-4 PH e kotsing ea ho bola. Sena se hloka tšireletso e eketsehileng.

Mechine:17-4 PH e ka etsoa ka mokhoa o thata le o nang le tharollo. Ho itšetlehile ka boima, machinability e fapana, sena se tla itšetleha ka boemo.

Pakeng tsa 1020 ° C le 1050 ° C thepa 17-4 PH e na le tharollo-annealed. Sena se lateloa ke ho pholisa ka potlako - metsi, oli kapa moea. Sena se itšetlehile ka karolo ea sefapano sa thepa.

Ho netefatsa phetoho e feletseng ho tloha ho austenite ho ea ho martensite, thepa e tlameha ho ba le bokhoni ba ho pholile mocheso oa kamore.
