Kunyangwe ari magiya anotenderera pasi pemutoro unorema kana mashaft anoshingirira kudzokororwa kufamba, zvinhu zvinofanirwa kugadzirwa kubva kuzvinhu zvakaomarara kuti zvigare. Imwe yesimbi inovimbwa nayo munharaunda iyi ndeye4140 alloy simbi.
Inozivikanwa nekuda kwesimba rayo remagetsi uye kusimba, 4140 zvakare inozvirumbidza inoshamisa kupfeka kuramba-kana yakagadziriswa nemazvo.sakysteelinoongorora kuti 4140 simbi yakaoma sei kana zvasvika pakuramba kupfeka, uye nei chiri chinhu chakakodzera chepamusoro-kushushikana, kupfeka-kwepamusoro maapplication.
Chii chinonzi 4140 Steel?
4140 achromium-molybdenum yakaderera-alloy simbiiyo inopa yakasarudzika musanganiswa wesimba, kuomarara, kuomarara, uye kupfeka kuramba. Iyo ndeye AISI-SAE simbi yekugadzika system uye inowanzoshandiswa mukugadzira zvinhu chaizvo, inorema-basa muchina, uye midziyo.
Yakajairika Chemical composition:
-
Kabhoni: 0.38 - 0.43%
-
Chromium: 0.80 - 1.10%
-
Manganese: 0.75 - 1.00%
-
Molybdenum: 0.15 - 0.25%
-
Silicon: 0.15 - 0.35%
Iyo chromium inovandudza kuoma uye kupfeka kuramba, nepo molybdenum inowedzera kuomarara uye kusimba kwepamusoro-tembiricha. Aya alloying elements anoita4140 simbiyakakodzera kune zvikamu zvinofanirwa kuramba kukuvara kwepamusoro kwenguva yakareba.
Chii chinonzi Wear Resistance?
Pfeka kurambaKugona kwechinhu kutsungirira kurasikirwa kwepasi kunokonzerwa nekuita kwemuchina. Ichi chiito chinogona kusanganisira:
-
Abrasion(kukwesha, kukwesha)
-
Adhesion(frictional transfer of material)
-
Kukukurwa kwevhu(kukanganisa kwezvimedu kana mvura)
-
Kushushikana(micro-kufamba pasi pemutoro)
Kunyanya kupfeka kuramba kunoreva kuti chikamu chichagara kwenguva yakareba mubasa, kuderedza mari yekugadzirisa uye nguva yekuderera.
Iyo 4140 Simbi Inoita Sei Mukupfeka Kupokana?
4140 simbi haisi iyo yakaomesesa simbi pamusika, asi kupfeka kwayo kuramba ndikozvikuru customizable. Kuburikidza zvakakodzerakupisa kurapwa, iyi simbi inogona kuchinjwa kubva kune machinable, ine mwero-simba zvinhu kuva yakaoma, isingapfekeki simba.

At sakysteel, tinowanzo kupa 4140 simbi mukudzikama uye kuzvidzora mamirirokuwedzera simba uye kupfeka kushanda. Izvi zvinoita kuti ive yakanakira zvinhu zvine simba senge shafts, axles, uye giya blanks.
Mechanisms Kuseri kwe4140's Wear Resistance
Zvinhu zvakati wandei zvinokonzeresa pakupfeka-resistant zvivakwa zve4140 alloy simbi:
-
Chromium Content
Inokwidziridza kuoma uye inopikisa kupfeka abrasive. -
Molybdenum Additions
Kuvandudza simba uye kuderedza njodzi yekupisa-kunyorovesa pane yakakwirira tembiricha. -
Fine Microstructure
Inopisa-yakagadziriswa 4140 inoumba yunifomu yakashatirwa martensite chimiro chinopokana deformation uye scuffing. -
Pamusoro Kuoma Kudzora
Simbi inogona kuomeswa kusvika pakati kana kuomeswa nepamusoro pepamusoro, ichipa kuchinjika kune chaiwo maapplication.
Kuenzanisa 4140 Kupfeka Kupokana kune Zvimwe Zvishandiso
4140 vs 1045 Carbon Steel
4140 ine zvakanyanya nani kupfeka kuramba nekuda kwekuoma kwepamusoro uye alloy zvemukati. 1045 inonyanya kukodzera kune yakaderera-kushushikana maapplication.
4140 vs Tool Steels (semuenzaniso, D2, O1)
Zvishandiso zvesimbi senge D2 zvinopa kupfeka kwepamusoro kuramba mumamiriro akanyanya, asi zvakanyanya brittle uye zvakaoma kumuchina. 4140 inorova chiyero chirinani chezvikamu zvine simba zvinoda zvese kusimba uye kuoma.
4140 vs Stainless Simbi (semuenzaniso, 316)
Simbi dzisina tsvina dzinodzivisa ngura asi dzinopfeka nekukurumidza pasi pemutoro. 4140 inosarudzirwa nzvimbo dzakaoma, dzemuchina uko kukweshera kunokuvadza kupfuura ngura.
Chaiyo-Nyika Zvishandiso Zvinovimba ne4140's Wear Resistance
Nekuda kwekuomarara kwayo uye kuomarara kwayo, 4140 inoshandiswa mumhando dzakasiyana dzezvinhu zvinopfekwa:
