5140 ipleyiti yentsimbi 1.7035 41Cr4 SCr440 intsimbi yentsimbi

Yintoni i-AISI 5140 yentsimbi?

Ibakala le-ASTM 5140 lelinye ibakala lentsimbi yolwakhiwo kwi-ASTM A29 esemgangathweni osetyenziswa ngokubanzi. I-5140 ipleyiti yensimbi isetyenziswa ngokubanzi kwiindawo eziphantsi kunye nezimodareyitha ezigxininiswe kwizithuthi, iinjini kunye noomatshini apho kunzima, ukunxiba ukuxhathisa indawo kuyadingeka. I-Gnee yingcali ye-5140 yepleyiti kunye nomthengisi webha engqukuva kwaye sigcina uluhlu olubanzi lwesayizi ye-5140 yepleyiti esitokhweni ukuze ithunyelwe ngokukhawuleza. Qhagamshelana nathi ngayo nayiphi na i-AISI 5140 isicelo sempahla yepleyiti kunye nexabiso eliphezulu le-5140 yexabiso lentsimbi.

Inzuzo yoKhuphiswano ye-AISI 5140 yepleyiti yentsimbi e-Gnee:

• Ifumaneka kwisitokhwe ukuze ithunyelwe ngokukhawuleza
• Amandla aphezulu,
• Ukunyamezela okuphezulu
• Ukuqina okulungileyo
• Ukuchasana okuphezulu kwiipropati ze-thermal.
• Ixabiso lokukhuphisana

1. Uluhlu lonikezelo lwe-AISI/ASTM 5140

Ibha eRound: ububanzi 20mm - 300mm

Ipleyiti yentsimbi kunye neBlock yentsimbi: ubukhulu 10-200mm x ububanzi 300-2000mm

• I-10-80mm ubukhulu be-5140 ipleyiti iyafumaneka ngalo lonke ixesha kwisitokhwe,
• I-90-200mm ipleyiti yobukhulu iza kuba yimveliso entsha kwiintsuku eziyi-15-30 zokukhokela.

UkuGqiba komphezulu: uMphezulu oMnyama, uMphezulu oMiliweyo okanye uMphezulu oGcwecwe ngokweemfuno ezinikiweyo.

5. Ukwenziwa kwe-5140 Alloy Steel

Ubushushu bokwenza okushushu: 1050-850℃.

6. ASTM 5140 Steel Heat Treat

• I-Soft Annealing

Fudumeza ukuya kwi-680-720 ℃, pholile ngokucothayo. Oku kuya kuvelisa ubukhulu be-5140 ubulukhuni be-241HB (ubunzima beBrinell).

7. Izicelo ze-AISI Grade 5140

I-AISI 5140 yensimbi ingasetyenziselwa iindawo eziphantsi kunye nezimodareyitha ezigxininisiweyo zezithuthi, iinjini kunye noomatshini apho kunzima, ukunxiba ukuxhathisa indawo kuyadingeka. Ukuqina komphezulu kuqina malunga ne-54 HRC. Iintsimbi ze-SAE 5140 zinokuba zezobunjineli baselwandle, iiplanti zokulungisa imichiza, iibhoyila kunye neenqanawa zoxinzelelo, izixhobo zamandla enyukliya njl.njl.

Ukuba unemibuzo malunga ne-5140 specs, okanye nayiphi na imibuzo malunga ne-5140 vs 4130, 5140 vs 4340 njl, nceda uqhagamshelane nathi ngenkxaso yobugcisa nangaliphi na ixesha.
