Indlela Yokufudumeza Intsimbi Engagqwaliyo Eyi-17-4 PH

Intsimbi engagqwaliyo ye-17-4 PH, eyaziwa ngokuba yiI-AISI 630, yenye yezona ntsimbi zingenasici ezisetyenziswa kakhulu ekuqiniseni imvula. Ixatyiswa ngenxa yayoamandla aphezulu, ukumelana nokugqwala, kunye nobunzima, okwenza ukuba ifaneleke kumashishini anzima afana neenqwelo-moya, ioyile negesi, ukucubungula iikhemikhali, ukuvelisa umbane, kunye nokusetyenziswa kolwandle.

Eyona nto ibalulekileyo ekusebenziseni intsimbi engagqwaliyo ye-17-4 PH kukubainkqubo yonyango lobushushu, nto leyo evumela iinjineli ukuba zilungise amandla ezinto, ukuqina kwazo, kunye nokumelana nokugqwala kwazo kwiindlela ezahlukeneyo zokusebenza. Eli nqaku lichaza ngokweenkcukachaindlela yokufudumeza intsimbi engagqwali ye-17-4 PH, iimeko ezahlukeneyo zeemeko (ezifana ne-H900, H1025, H1150), iinkqubo zenyathelo ngenyathelo, kunye nezinto ezibalulekileyo ekufuneka ziqwalaselwe ukuqinisekisa ukusebenza kakuhle.

Yintoni i-17-4 PH Stainless Steel?

Intsimbi engagqwaliyo ye-17-4 PH yiintsimbi engagqwaliyo eqinisa imvula ye-martensiticequlethe i-chromium, i-nickel, kunye ne-copper.

Ulwakhiwo lweeKhemikhali (Oluqhelekileyo):

  • I-Chromium (Cr): ~15–17%

  • I-Nickel (Ni): ~3–5%

  • I-Copper (Cu): ~3–5%

  4. Uzinzo olunemilinganiselo

    • Unyango olufanelekileyo lobushushu lunciphisa ukugqwetheka kunye noxinzelelo ngexesha lokulungiswa.

Inkqubo Yonyango Lobushushu kwi-17-4 PH Stainless Steel

Inyathelo 1: Ukutsalwa kwesisombululo (Imeko A)

  • Fudumeza izinto ngokulinganayo ukuze1900°F (1040°C).

  • Bamba kubushushu obuphantsiUbuncinane bemizuzu engama-30.

  • Iphola ngokukhawuleza ukuya kubushushu begumbi (iphole ngomoya okanye itshise ioyile kuxhomekeka kubukhulu bayo).

Isiphumo:Ivelisa isakhiwo esithambileyo se-martensitic esisebenzisekayo nesilungele unyango lokwaluphala.

Inyathelo lesi-2: Ukuqina kwemvula (Ukwaluphala)

Emva kokucocwa kwesisombululo, izinto ziyadlulaunyango lokwaluphalakumaqondo obushushu alawulwayo. Eli nyathelo libangela ukuba kubekho iiprecipitates ezincinci (ingakumbi izigaba ezityebileyo ngobhedu), nto leyo eqinisa i-martensitic matrix.

Iimeko Eziqhelekileyo Zokwaluphala:

  1. Imeko ye-H900

    • Fudumeza ukuya900°F (482°C)iyure e-1.

  2. Imeko ye-H1025

    • Fudumeza ukuya1025°F (552°C)iiyure ezi-4.

    • Umoya upholile.

    • Amandla nokuqina okulinganayo.

  3. Imeko ye-H1075

    • Fudumeza ukuya1075°F (580°C)iiyure ezi-4.

    • Umoya upholile.

    • Amandla aphantsi kune-H900, ukuqina okuphuculweyo.

  4. Imeko ye-H1150

    • Fudumeza ukuya1150°F (621°C)iiyure ezi-4.

    • Umoya upholile.

    • Ukuqina okugqwesileyo kunye nokumelana nokugqwala, ubunzima obuphantsi.

  5. Unyango oluphindwe kabini lwe-H1150 (H1150D)

    • Fudumeza ukuya kwi-1400°F (760°C) iiyure ezi-2 → Pholisa umoya.

    • Phinda ufudumale ukuya kwi-1150°F (621°C) iiyure ezi-4 → Pholisa umoya.

    • Iphucula ukumelana nokuqhekeka koxinzelelo.

Iipropati ngokwemeko yoNyango loBushushu

Imeko Amandla okuThamba (ksi) Amandla okuVuna (ksi) Ubulukhuni (HRC) Amanqaku
H900 190–200 170–180 44–47 Amandla aphezulu, ubulukhuni obuphantsi
H1025 ~170 ~150 38–42 Iipropati ezilinganayo
H1075 ~155 ~135 35–38 Ukuqina okungcono
H1150 ~135 ~105 28–32 Eyona ndlela ilungileyo yokumelana nokugqwala
H1150D ~140 ~110 28–32 Ukumelana nokugqwala koxinzelelo oluhle kakhulu

Izinto Ezichaphazela Unyango Lobushushu

  1. Ubukhulu beCandelo
