Investment Casting Material Selection Guide: Kufananidza Alloys kune Chikumbiro chako

Nei Kusarudzwa Kwezvinhu Kunonyanya Kukosha muKuisa Mari

Investment casting's musimboti mukana wedhizaini rusununguko - padhuze-net-shape geometries, madziro matete, uye zvemukati maficha asingagone kuwanikwa nekugadzira kana jecha kukanda. Asi rusununguko irworwo runoita kuti pave nechisarudzo chenyama. Iyo yekudyara yekukanda maitiro inobata alloys kune yakanyungudutswa-simbi tembiricha inochengetwa muhombodo dzeceramic, uye imwe neimwe alloy mhuri inodyidzana zvakasiyana neiyo nharaunda: carbon steels inoregerera, magiredhi asina tsvina anoda kudzorwa mhepo, uye superalloys inoda chaiyo yekupisa kwekutonga. Kusarudza alloy yako yekutanga haigone kugara itenzi iresiphi yeporosity, inclusions, uye kunonoka kutakura.

Mibvunzo Mishanu Inoronga Chero Chisarudzo cheAlloy

Usati wavhura dhairekitori rezvinyorwa, pindura iyi mibvunzo mishanu nechikwata chako chekugadzira:

1. Chikamu chichatakura mitoro ipi? Static simba, kuneta bhasikoro, uye kukanganisa imwe neimwe poindi kune dzakasiyana alloy mhuri.
2. Ichashanda mhoteredzo ipi? Corrosive media, tembiricha yakakwira, uye abrasive kuonana kupfupisa munda nekukurumidza.
3. Ndezvipi kushivirira uye pamusoro pezvinodiwa? Mamwe maalloys anobata zvakasimba se-cast kushivirira kupfuura mamwe.
4. Chikamu chichagadzirwa sei? Harder alloys anowedzera machining nguva uye mutengo wekushandisa.
5. Chikumbiro chacho chinombonyatso simbisa chii? Kunyanya-kutsanangura zvinhu ndizvo zvinowanzoitika - uye zvinodhura - kukanganisa kwekusarudza.

Carbon uye Low-Alloy Steels: Iwo Workhorses

Yakajairika mamakisi : AISI 1020/1030/1045, AISI 4130, AISI 4140/42CrMo4, AISI 8620, 16MnCr5

Carbon uye yakaderera-alloy simbi inoverengera iyo yakawanda yekudyara castings nehuwandu, uye nechikonzero chakanaka. Ivo vanopa yakanakisa chiyero chesimba, kuoma, weldability, uye mutengo - kazhinji mutengo wakaderera wezvinhu pakirogiramu chero inokandwa engineering alloy.

• AISI 1020/1030 (plain kabhoni) : Yakanakira mabhuraketi, levers, housings, uye mafittings apo simba riri pakati nepakati (400–600 MPa tensile) rinokwana. Excellent machinability.
• AISI 4130/4140 (chromium-molybdenum) : Sarudzo yekusarudzika yezvakanyanya-kushushikana zvikamu - hydraulic valve miviri, tsvimbo dzekubatanidza, magiya, uye oiri yemidziyo. Yakadzimwa-uye-yakatsamwa 4140 inosvika 930+ MPa simba rekusimba nekunaka kuneta kuramba.
• AISI 8620 (nickel-chromium-molybdenum) : Yakatsanangurwa panodiwa kuomeswa kwekesi - magiya mabheji, camshafts, uye nzvimbo dzekupfeka dzinoda kesi yakaoma carburized pamusoro peiyo yakaoma core.

Sarudzo yezano : Kana chikamu chako chikashanda muchimiro chiri pasi pe 300 °C pasina kukosha kwekuora, simbi yakaderera-alloy ndiyo inenge iri mhinduro ine mari. Usakwidziridze kune isina tsvina pasina chikonzero chinofambiswa necorrosion - mutengo wepamusoro i2-4 ×.

Stainless Simbi: Corrosion uye Heat Resistance

Magiredhi emhando : CF8/304, CF8M/316, CA15/410, 17-4 PH, 2205 duplex

Simbi dzisina tsvina dzinotonga muvharuvhu, pombi, kugadzira chikafu, marine, uye makemikari kushandiswa. Investment casting inobata magiredhi asina tsvina zvakanaka, kunyangwe yakadzorwa kunyungudika uye ganda remhepo zvakakosha kudzivirira kabhoni pickup uye oxidation inclusions.

• CF8 (304) : Iyo general-chinangwa austenitic giredhi remvura, chikafu, uye munyoro makemikari sevhisi. Yakanaka corrosion kuramba, yakanakisa kuumbwa, isiri-magnetic.
• CF8M (316) : Inowedzera molybdenum yepitting resistance against chlorides - the standard choice for desalination, marine hardware, chemical valve bodies, and pharmaceutical equipment.
• CA15 (410) / CA6NM (410NiMo) : Martensitic magiredhi asingasviki anobatanidza kusimba kwepakati nepakati nesimba rakawanda - rinoshandiswa mumhanyi weturbine, valve trim, uye pombi shafts.
• 17-4 PH : Kunaya-kuomesa tsvina kuburitsa 1,100+ MPa kusimba kwesimba nekunaka kwekuora. Iyo yekuenda kune yepamusoro-inoshanda mavharuvhu madzinde, aerospace fittings, uye tooling.
• Duplex 2205 : Inoda kupeta kaviri simba regoho re316 ine superior chloride stress-corrosion cracking resistance, ye offshore uye aggressive chemical duty.

Sarudzo zano : Matanidza giredhi risingasviki kune chaiyo inoora michina. 304 inokundikana munzvimbo dzechloride umo 316 inorarama; 316 pachayo inokundwa nekushushikana-kukoromoka kutsemuka uko duplex mamakisi haaite.

Ductile Iron uye Gray Iron: Damping uye Value

Magiredhi emhando : QT400-18, QT450-10, QT500-7, QT700-2, GG25

Nepo yakawanda yakabatana nekukandwa kwejecha, ductile iron inokandwawo - kunyanya kune zvikamu izvo musanganiswa wayo wakasiyana-siyana wesimba, kunyorova, uye pedyo-simbi kusimba pamutengo wakaderera kunotonga.

• QT450-10 / QT500-7 : Zvivakwa zvedzimba, ekisi inotsigira, kumiswa zvikamu. Elongation ye7-10% inopa kuoma kwechokwadi.
• QT700-2 : Yepamusoro-simba mashandisirwo - ekupedzisira dhiraivha dzimba, crankshafts, magiya - uko vibration inonyorovesa uye inomanikidza simba zvine basa.
• GG25 (grey iron) : Compressor uye mabhureki zvikamu uko kunyorovesa uye kupisa conductivity kunodarika tensile zvinodiwa.

Copper Alloys: Bearings uye Marine Service

Magiredhi emhando : C95800 NiAl bronze, C83600 tsvuku tsvuku, C95400 aluminium bronze

Mhangura alloys inowana nzvimbo yadzo uko simbi isingaende: yakanyudzwa nharaunda dzemugungwa, kubereka uye mabushing application, uye spark-isina turusi yemhepo ine njodzi.

• C95800 Nickel-Aluminium Bronze : The marine propeller standard — 600+ MPa tensile, yakanakisa cavitation uye yegungwa corrosion resistance, uye anti-fouling properties.
• C95400 Aluminium Bronze : Yakakwirira-yakasimba mabhengi, magiya, uye zvigaro zvevharuvhu zvinoda mutoro wekutakura kupfuura akajairwa mabhuronzi.

Superalloys uye Specialty Materials

Kune zvikamu zve turbine gasi, exhaust masisitimu, uye petrochemical hardware inoshanda pamusoro pe600 ° C, kukanda kwekudyara ndiyo yega nzira inoshanda. Cobalt-base (Stellite) uye nickel-base alloys anochengetedza simba patembiricha apo masimbi akazvipira kwenguva refu. Aya maapplication anoda nyanzvi dzekuwana ane vacuum kunyunguduka kugona - chikamu uko kusarudzwa kwezvinhu uye kusarudzwa kwevatengesi kunova kusinga patsanurwe.

The Cost-Performance Reality Check

Muenzaniso unobatsira wepfungwa unoisa iyo yakajairwa alloy mhuri neinoda mari yezvinhu:

1. Gray iron / carbon simbi (yekutanga 1.0 ×)
2. Ductile iron (1.1×)
3. Yakaderera-alloy simbi (1.2–1.5×)
4. 400-yakatevedzana isina tsvina (1.5–2×)
5. 300-yakatevedzana isina tsvina (2–3×)
6. 17-4 PH / duplex (3–4×)
7. Midziyo yebhuronzi (3–5×)
8. Superalloys (8–20×+)

Iyo pateni yakajeka: nhanho imwe neimwe kumusoro kwemanera inotenga chaiyo kugona - simba, corrosion resistance, kana kupisa kupisa. Bhadhara kugona kudiwa neapplication yako, kwete iyo inodiwa nemukwikwidzi wako.

Iyo KST Casting Inotsigira Sarudzo Yako Yezvinhu

Kusarudzwa kwezvinhu hakufanire kuitika kwakasiyana kubva pakugadzirwa. KuNingbo Ruican, timu yedu yeinjiniya inoongorora yega RFQ yezvigadzirwa-maitiro akakodzera asati atora mashoko. Isu tinocherekedza pamusoro-zvakatsanangurwa zvinokwidza mutengo, tinokurudzira zvakaenzana zvinovandudza kukasa, uye tinopa mhinduro yeDFM inosanganisa maficha uye inoderedza machining. Ne IATF 16949 certification, spectrometer verification pane kupisa kwese, uye yakazara EN 10204 3.1 chitupa chechinhu, unogamuchira vimbiso yakanyorwa yekuti alloy muchikamu chako ndiyo alloy yawakatsanangura.
