Chii chinonzi AISI 5140 simbi?
ASTM giredhi 5140 igiredhi rimwe chete resimbi yesimbi muASTM A29 yakajairwa kuti ishandiswe zvachose. 5140 simbi ndiro inoshandiswa zvakanyanya muzvikamu zvakaderera uye zvine mwero zvakasimbiswa zvemotokari, injini nemichina uko kwakaoma, kupfeka kupikisa nzvimbo kunodiwa. Gnee inyanzvi ye5140 plate & round bar supplier uye tinochengeta saizi yakakura ye 5140 plate iripo kuti iendeswe nekukurumidza. Bata isu kune chero AISI 5140 ndiro yekukumbira zvinhu uye yakanakisa 5140 giredhi simbi mutengo.
Kukwikwidza Kunobatsira kweAISI 5140 zvinhu simbi ndiro muOtai:
- Inowanikwa mustock kuti iendeswe nekukurumidza
- Simba guru,
- High tenacity
- Kuomarara kwakanaka
- Kunyanya kupikisa kune zvinhu zvinopisa.
- Mutengo wemakwikwi
1. Supply Range yeAISI/ASTM 5140
Round Bar: dhayamita 20mm - 300mm
Steel Plate uye Steel Block: ukobvu 10-200mm x upamhi 300-2000mm
- 10-80mm ukobvu 5140 ndiro inowanikwa nguva dzese mustock,
- 90-200mm ukobvu ndiro kuve ichangoburwa kugadzirwa mumazuva 15-30 kutungamirira nguva.
Pamusoro Pekupedzisira: Musoro Wenhema, Musoro Wepamusoro kana Wakapukutwa Wepamusoro sekuenderana nezvinodiwa.

5. Kugadzirwa kwe5140 Alloy Steel
Kupisa kuumba tembiricha: 1050-850 ℃.
6. ASTM 5140 Steel Heat Treat
Kupisa kusvika 680-720 ℃, tonhorera zvishoma nezvishoma. Izvi zvinoburitsa hurema hwe5140 hwe241HB (Brinell hardness).
- Noramlizing yesimbi giredhi 5140
Tembiricha: 840-880 ℃.
- Kuomesa 5140 simbi yakagadzirwa
Kuomesa kubva pakupisa kwe820-850, 830-860 ℃ kuchiteverwa nemvura kana kudzima mafuta.
- Kupisa kweSAE 5140 zvinhu
Kupisa tembiricha: 540-680 ℃.
7. Maapplications eAISI Grade 5140
AISI 5140 simbi inogona kushandiswa kune yakaderera uye ine mwero yakasimbiswa zvikamu zvemotokari, injini nemichina uko yakaoma, inopfeka inopikisa nzvimbo inodiwa. Kuomarara kwepamusoro kwakaoma nezve 54 HRC. SAE 5140 masimbi anogona zvakare kuve emugungwa engineering indasitiri, makemikari ekugadzirisa zvidyarwa, boiler & midziyo yekumanikidza, zvidyarwa zvemagetsi enyukireya nezvimwe.
Kana iwe uine mibvunzo nezve 5140 specs, kana chero mibvunzo nezve 5140 vs 4130, 5140 vs 4340 nezvimwe, ndapota taura nesu kuti tiwane rutsigiro rwehunyanzvi chero nguva.
