Mazita Ekutengeserana Anowanikwa:17-4ph,S51740,SUS630,0Cr17Ni4Cu4Nb,05Cr17Ni4Cu4Nb,W. Nr./EN 1.4548
17-4 Stainless is an age-harding martensitic stainless inobatanidza simba rakakwirira nekudzivirirwa kwekuora kwesimbi isina tsvina.Kuomesa kunowanikwa nekanguva-pfupi, nyore-kupisa kurapwa.Kusiyana neyakajairwa martensitic simbi isina simbi, senge mhando 410, 17-4 inokwenenzverwa.Iyo simba, kusadzivirirwa nekuora uye kugadzirwa kwakareruka kunogona kuita 17-4 isina tsvina inodhura-inoshanda kutsiva yakakwirira simba kabhoni simbi pamwe nemamwe mamakisi asina tsvina.
Pamushonga wekurapa tembiricha, 1900 ° F, simbi ndeye austenitic asi inoshandura kune yakaderera-kabhoni martensitic chimiro panguva yekutonhodza kusvika kukamuri tembiricha.Shanduko iyi haina kukwana kutozosvikira tembiricha yadzika kusvika pa90°F.Kutevera kudziya kune tembiricha ye900-1150 ° F kweawa imwe kusvika mana kunaya kunosimbisa alloy.Uku kuomesa kurapa zvakare kunoshatirisa iyo martensitic chimiro, ichiwedzera ductility uye kuoma.

Sei 17-4PH ?
•Nyore kugadzirisa chiyero chesimba, ndiko kuburikidza nekuchinja kwekupisa kurapwa kugadzirisamartensite phase shanduko uye kuchembera
kurapwa kwesimbi ichiita kunaya kwemvura kuomesa chikamu.
•Corrosion kuneta kuramba uye kusagadzikana kwemvura.
•Welding:Mumamiriro ekugadzirisa kwakasimba, kuchembera kana kuwedzeredza, iyo alloy inogona kusungirirwa nenzira, isina preheating.
Kana ichida iyo welding simba padhuze nesimba resimbi rekuchembera rakaomeswa, ipapo iyo alloy inofanirwa kuve yakasimba mhinduro uye kuchembera kurapwa mushure mekunama.
Iyi alloy yakakodzerawo kubhuroka, uye yakanyanya kupisa tembiricha ndiyo tembiricha yemhinduro.
•Corrosion resistance:Alloy corrosion resistance inopfuura chero ipi zvayo yakaomeswa simbi isina tsvina, mumvura yakadzikama iri nyore kutambura nekuora kana kutsemuka.Muindasitiri yekemikari yepetroleum, kugadzira chikafu uye indasitiri yemapepa ine kunaka kwekusagadzikana.
17-4PH Nzvimbo yekushandisa:
•Offshore mapuratifomu, iyo helikopta dhizaini, mamwe mapuratifomu.
•Indasitiri yezvokudya.
•Pulp uye indasitiri yemapepa.
•Nzvimbo (turbine blade).
•Mechanical parts.
•Madhiramu emarara enyukireya.
