Menene AISI H12 Karfe

Karfe mai zafi na AISI H12 yana ɗaya daga cikin matakan da aka fi amfani da su a cikin dangin ƙarfe na kayan aiki, wanda aka san shi da haɗinsa mai ban mamaki na tauri, juriya ga zafi, da ƙarfin lalacewa. Yayin da masana'antu ke ci gaba da buƙatar kayan aiki masu ƙarfi da ɗorewa don yin simintin ƙarfe, ƙirƙira, da fitarwa,AISI H12ya kasance zaɓi mafi soyuwa tsakanin injiniyoyi da masu kera kayan aiki a duk duniya.

A cikin wannan labarin, za mu yi cikakken bayani game da abin da ƙarfe AISI H12 yake, abubuwan da ke cikin sinadarai, halayen injiniya, tsarin maganin zafi, aikace-aikacen masana'antu na yau da kullun, da kuma dalilin da yasaSAKYSTELyana ɗaya daga cikin masu samar da kayan aikin H12 masu zafi.

1. Gabatarwa ga AISI H12 Karfe

AISI H12 ƙarfe ne mai amfani da zafi wanda aka yi da chromium wanda ke cikin jerin ƙarfe na H, wanda ya haɗa da maki kamar H10, H11, da H13. Ana amfani da waɗannan ƙarfe galibi don amfani da kayan aiki waɗanda suka shafi yanayin zafi mai yawa da matsin lamba na inji.

Sunan "H" yana nufin "Aiki Mai Zafi," wanda ke nuna cewa AISI H12 an tsara shi ne don riƙe tauri da ƙarfi ko da lokacin da aka yi amfani da shi a yanayin zafi mai yawa. Wannan matakin yana ba da kyakkyawan juriya ga fashewawar gajiyar zafi, iskar shaka, da laushi a ƙarƙashin ɗaukar zafi na dogon lokaci.

AISI H12 an daidaita shi bisa ga wasu ƙa'idodi masu kama da juna:

  • AISI H12 / UNS T20812

  • Werkstoff No. 1.2605

  • DIN X35CrW5 / X35CrMoV5-1

  • JIS SKD6

Saboda haɗakar tauri, tauri, da juriya ga duba zafi, AISI H12 ya dace da kayan aiki masu nauyi, injinan kashe zafi, da kuma injinan fitar da iska.

2. Sinadarin AISI H12

Ana bayyana aikin ƙarfe AISI H12 ta hanyar haɗakar sinadarai masu kyau. Kasancewar chromium, molybdenum, da tungsten yana ba da ƙarfi mai zafi da juriya ga iskar shaka, yayin da carbon ke tabbatar da tauri da juriya ga lalacewa.

Sinadarin Abun ciki (%)
Carbon (C) 0.35 – 0.45
Chromium (Cr) 4.75 – 5.50
Molybdenum (Mo) 1.10 – 1.75
Tungsten (W) 1.00 – 1.75
Vanadium (V) 0.20 – 0.60
Silikon (Si) 0.80 – 1.20
Manganese (Mn) 0.25 – 0.50
Nickel (Ni) ≤ 0.3
Sulfur (S) + Phosphorus (P) ≤ 0.03

Wannan abun da ke ciki yana samar da ingantaccen tsari mai kyau wanda ke tallafawa daidaiton zafi da na inji. Abubuwan da ke cikin chromium suna ƙara juriya ga tsatsa da riƙe tauri, yayin da tungsten da molybdenum ke ƙarfafa ƙarfe a yanayin zafi mai yawa.

3. Halayen Inji na AISI H12

Aikin injina na AISI H12 ya sa ya dace da ayyukan da suka shafi hawan matsi da zafin jiki. Abubuwan da aka saba amfani da su na injina bayan maganin zafi sune kamar haka:

Kadara Darajar da Aka Saba
Tauri (An rufe shi) ≤ 229 HB
Taurin kai (Mai tauri da kuma mai tsauri) 44 – 52 HRC
Ƙarfin Taurin Kai 1500 – 1900 MPa

Ƙarawa 10 – 15%
Taurin Tasiri Madalla a yanayin zafi mai yawa

AISI H12 yana haɗa ƙarfin zafi mai yawa da tauri, wanda ke rage haɗarin fashewa yayin aikin simintin ƙarfe ko ƙirƙirar ƙarfe. Wannan saitin kayan yana bawa ƙarfe damar yin aiki da kyau a lokacin da ake maimaita zagayowar zafi.

4. Tsarin Maganin Zafi

Daidaiton maganin zafi yana da mahimmanci don inganta aikin injin AISI H12. Tsarin maganin zafi na yau da kullun ya haɗa da matakai masu zuwa:

Ƙararrawa

  • Zafi zuwa 850–900°C.

  • A daka na tsawon awanni 2-4 ya danganta da girman sashe.

  • Sanyaya a hankali a cikin tanda zuwa digiri 600 na Celsius, sannan a sanyaya a cikin iska.

  • Sakamako: Tsarin mai laushi tare da tauri ≤ 229 HB don injina.

Ana dumamawa kafin lokaci

  • A fara dumamawa a hankali a matakai biyu: da farko zuwa 450–500°C, sannan zuwa 850–900°C.

  • Sakamako: Taurin har zuwa 52 HRC.

Mai jurewa

  • Sai a yi zafi nan da nan bayan an taurare.

  • Yanayin zafin jiki na yau da kullun: 500–650°C.

  • Ana ba da shawarar yin amfani da tempering sau biyu don inganta tauri.

Bayan an tace, ana iya sarrafa taurin ƙarshe bisa ga aikace-aikacen da ake so - gabaɗaya tsakaninDaga 44 zuwa 52 HRC.

5. Fa'idodin Karfe AISI H12

AISI H12 yana da matuƙar daraja saboda daidaiton halayensa. Ga manyan fa'idodin da suka sa ya zama abin dogaro ga kayan aikin masana'antu:

  1. Juriyar Gajiya Mai Tsanani
    Yana jure tsagewa a lokacin da ake maimaita dumama da sanyaya.

  2. Tauri Mai Kyau
    Yana kiyaye ƙarfin tasiri koda a ƙarƙashin matsin lamba da zafin jiki mai yawa.

  3. Kwanciyar Hankali Mai Kyau

AISI H12yana ba da ƙarfi mai zafi da juriya ga tsagewa idan aka kwatanta da H11, yayin da yake kiyaye tauri mafi kyau fiye da H13 a wasu aikace-aikace. Wannan ya sa ya dace musamman ga mayukan ƙera abubuwa masu nauyi da kuma molds na extrusion.

8. Abubuwan da ake la'akari da su wajen kera da walda

Inji

Ya kamata a yi amfani da AISI H12 a yanayin da yake da annealed. Matsayin injinsa kusan kashi 75% ne na ƙarfe AISI 4140. Amfani da kayan aikin carbide da kuma kiyaye yanayin sanyaya mai kyau suna da mahimmanci don tsawaita rayuwar kayan aiki.

Walda

Ana iya walda ta hanyar dumamawa kafin lokaci (250–350°C) da kuma dumama bayan walda don guje wa tsagewa. Abubuwan da aka ba da shawarar cikawa suna da kama da ƙarfen tushe.

Maganin Fuskar

Domin tsawon rai, ana iya amfani da maganin saman kamar nitriding ko PVD. Fuskokin da aka yi da nitrided AISI H12 suna nuna ingantaccen tauri da juriyar lalacewa ba tare da asarar ƙarfin tushe ba.

9. Tsarin Samarwa da Girman Kayayyaki

SAKYSTELyana samar da kayan aikin zafi na AISI H12 na ƙarfe a cikin siffofi da girma dabam-dabam, gami da:

  • Sandunan zagaye

  • Sandunan lebur

  • Faranti da tubalan

  • Ƙirƙirar billets

  • Ma'aikatan da aka riga aka yi musu aiki

Ana samar da dukkan kayan tare daEN 10204 3.1 Takaddun gwajin gwaji, yana tabbatar da sinadaran da aikin injiniya. Ana kuma samun ayyukan yankewa na musamman, injinan daidaitacce, da kuma maganin zafi bisa ga takamaiman buƙatun abokin ciniki.

10. Tabbatar da Inganci da Ma'auni

At SAKYSTEL, duk kayan AISI H12 ana samar da su ne bisa ga ƙa'idodin ƙasashen duniya kamar:

  • ASTM A681 - Kayan aiki Karfe Alloy

Kowace ƙungiya tana fuskantar tsauraran matakan kula da inganci, gami da gwajin ultrasonic, duba tauri, da kuma nazarin ƙarfe don tabbatar da cewa babu lahani a cikin aikin.

11. Nasihu don Rayuwar Kayan Aiki Mafi Kyau

Don cimma mafi kyawun rayuwar kayan aiki daga abubuwan AISI H12:

  1. Yi amfani da dumamawa mai kyau kafin a fara aiki.

  2. A guji yawan canjin yanayin zafi.

  3. Yi tempering sau biyu don ƙara tauri.

  4. A shafa nitriding don tsawaita taurin saman.

  5. A kula da man shafawa akai-akai a lokacin amfani da shi a wurare masu zafi.

Bin waɗannan ƙa'idodi yana tabbatar da tsawon rai na sabis, rage lokacin aiki, da kuma tanadin kuɗi ga masu amfani da masana'antu.

12. Kammalawa

AISI H12 ƙarfe ne mai aiki sosai wanda ke samar da ƙarfi, juriya ga zafi, da kwanciyar hankali a cikin mawuyacin yanayi na masana'antu. Daidaitaccen tsarin ƙarfe da juriya ga gajiyar zafi ya sa ya zama kayan da aka fi so don ƙera, ƙera siminti, da kayan aikin extrusion.

Tare da shekaru da yawa na ƙwarewar masana'antu da fitarwa,SAKYSTELyana samar da samfuran ƙarfe na AISI H12 masu inganci waɗanda suka cika ƙa'idodin ƙasashen duniya da buƙatun abokan ciniki. Ko kuna buƙatar tubalan da aka ƙirƙira, faranti masu yanke daidai, ko sandunan da aka shirya don injin,SAKYSTELyana tabbatar da inganci mai inganci, isarwa akan lokaci, da kuma tallafin fasaha na ƙwararru.
