Rudzii rweSimbi inonzi 4140?

Simbi ye4140 isimbi inozivikanwa zvikuru inozivikanwa nekusimba kwayo, kusimba kwayo, uye kushanduka-shanduka kwayo. Ndeyemhuri yesimbi dzechromium-molybdenum, ichipa musanganiswa wakasiyana wehunhu hwemakanika hunoita kuti ive sarudzo inofarirwa kushandiswa mumaindasitiri. Mainjiniya, vagadziri, uye vagadziri vanoshandisa simbi iyi zvakanyanya pazvinhu zvese kubva kuzvikamu zvemotokari kusvika kuzvikamu zvemichina.

Muchinyorwa chino cheSEO, sakysteel inopa ongororo yakazara ye4140 simbi, kusanganisira makemikari ayo, hunhu hwayo hwemakanika, maitiro ekurapa kupisa, uye mashandisirwo akajairika.

Kupatsanurwa kweSimbi ye4140

4140 isimbi ine alloy shoma inowira pasi peSAE-AISI classification system. Inozivikanwawo seAISI 4140, EN19 (muEurope)uyeSCM440 (muJapani)Zita rekuti "4140" rinoreva huwandu hwezvinhu zvakasanganiswa:

  • "41" inoratidza simbi yechromium-molybdenum

  • "40" inomiririra huwandu hwekabhoni hunofungidzirwa (0.40%)

Simbi ye4140 haisi simbi isina ngura, sezvo isina chromium yakakwana inodzivirira ngura. Asi, inokosheswa nekuda kwesimba rayo remuchina uye kuomarara mushure mekupisa.

Kuumbwa kweMakemikari eSimbi 4140

Kuumbwa kwemakemikari e4140 ndiko kunoita kuti ive neunyanzvi hwayo hwekugadzira zvinhu. Mhando dzakajairika dzinosanganisira:

  • Kabhoni (C):0.38% – 0.43%

  • Chromium (Cr):0.80% – 1.10%

  • Manganese (Mn):0.75% – 1.00%

  • Molybdenum (Mo):0.15% – 0.25%

  • Silikoni (Si):0.15% – 0.35%

  • Phosphorus (P):≤ 0.035%

  • Sarufa (S):≤ 0.040%

Zvinhu izvi zvinoshanda pamwe chete kuti zviwedzere kuomarara, kuramba kupfeka, uye kugara kwenguva refu, zvichiita kuti 4140 ive chinhu chinoshandiswa zvakanyanya pakushandisa zvikamu zvemakanika zvinoda simba.

Zvimiro zveSimbi ye4140

4140 ine mhando dzakasiyana-siyana dzehunhu hwemakanika, kunyanya mushure mekupisa kwakakodzera. Izvi zvinosanganisira:

  • Simba reKusimba:Kusvika ku1100 MPa (160 ksi)

  • Simba reKubereka:Inenge 850 MPa (123 ksi)

  • Kureba panguva yekuzorora:Inenge 20%

  • Kuoma:Kazhinji 197 kusvika 235 HB kana yakanyungudutswa, kusvika 50 HRC mushure mekudzima nekudziya.

Izvi zvinogona kusiyana zvichienderana nechimiro chesimbi (bhara, ndiro, forged) uye mamiriro ekurapa kupisa.

Kurapa Kupisa kweSimbi ye4140

Kurapa kupisa inzira inokosha inovandudza mashandiro e4140 simbiSimbi inogona kuita zvinotevera:

  1. Kunyungudutsa
    Kutonhodzwa zvishoma nezvishoma kubva pa850°C kuti michina ishande zvakanaka uye kuderedza kushushikana kwemukati. Izvi zvinoita kuti chimiro chive chakapfava uye chinopfava.

  2. Kugadzirisa zvinhu
    Inodziiswa kusvika pa870°C kuti igadzirise chimiro chegorosi. Inopa kusimba uye kusimba kwakaringana.

  3. Kudzima uye Kugadzirisa
    Inoomeswa nekupisa kusvika pa845°C uye inotonhorera nekukurumidza mumafuta kana mumvura, zvichiteverwa nekuomeswa kusvika padanho rekuoma kwaunoda. Izvi zvinowedzera simba uye kuramba kupera.

  4. Kuderedza Kushushikana
    Zvinoitwa pa650°C kuderedza kushushikana kunobva pakugadzira kana kusanganisa.

PaSakysteel, tinopa4140 simbimumamiriro akasiyana-siyana ekupisa zvichienderana nezvinodiwa nevatengi, zvichiita kuti application yako ishande zvakanaka.

Mabhenefiti eSimbi ye4140

  • Simba Rakakura Kusvika Pahuremu:Yakanakira kushandiswa kwemafuta anoderedza huremu.

  • Kuramba Kuneta Zvakanaka:Inotsungirira kutenderera kwemota, yakakodzera magiya nemashaft.

  • Kusimba Kwakanaka:Inowana kuoma kwakanyanya mushure mekudzima.

  • Kugona kushandiswa:Zvinogoneka nyore nyore kana zvakanyoroveswa kana kuti zvakajairwa.

  • Kugona kusundira:Inogona kusungirirwa nekupisa kwakakodzera uye kugadziriswa mushure mekusungirirwa.

Mabhenefiti aya anoita kuti simbi ye4140 ive sarudzo isingadhuri pakushandisa mainjiniya akawanda ane simba rakawanda.

Mashandisirwo esimbi ye4140

Nekuda kwesimba rayo remakanika uye kushanduka-shanduka, simbi ye4140 inoshandiswa mumaindasitiri akasiyana-siyana:

Kuenzaniswa Kwakaitwa 4140 Nedzimwe Simbi

Simbi yeKabhoni 4140 vs. 1045:
4140 inopa simba riri nani rekupfeka uye simba rakawanda rekusunga nekuda kwezvimedu zvinosanganisa alloying. 1045 yakachipa asi haina kusimba zvakanyanya.

4140 vs. 4340 Simbi:
4340 ine nickel yakawanda, ichipa kusimba kuri nani uye inodzivirira kuneta. 4140 inodhura zvishoma pakushandiswa kwakajairika.

4140 vs. Simbi Isina Kushanda (semuenzaniso, 304 kana 316):
Simbi dzisina ngura dzinodzivirira ngura asi dzine simba shoma. 4140 inonyanya kushandiswa kana zvinhu zvakawanda zvisina ngura munzvimbo dzine ngura.

Mafomu Anowanikwa pa sakysteel
