AISI 4140 Baja Baja, Plat Baja, Pemasok Flat, Stokis lan Eksportir. Baja paduan AISI SAE 4140 minangka spesifikasi baja paduan kromium molibdenum sing digunakake digunakake ing baja tarik dhuwur kanggo komponen, kayata poros, poros, baut, roda gigi lan aplikasi liyane. Padha karo alloy grade AISI 4130 chrome moly baja alloy nanging karo isi karbon rada luwih. Isi karbon sing luwih dhuwur saka baja AISI 4140 menehi kekuatan lan kemampuan perawatan panas sing luwih gedhe dibandhingake karo baja paduan AISI / ASTM 4130, nanging nduweni karakteristik weldability sing luwih murah.

5. Tempa
Preheat baja kasebut kanthi teliti, panas nganti 1150 oC - 1200 oC maksimum, tahan nganti suhu seragam ing saindhenging bagean.
Aja palsu ing ngisor 850 oC. Sawise operasi penempaan, potongan kerja kudu digawe adhem alon-alon.
6. AISI 4140 Steel Grade Heat Treatment
- Annealing
Panasake baja ASTM 4140 nganti 800 oC - 850 oC, tahan nganti suhu seragam ing saindhenging bagean lan adhem ing tungku.
- Normalisasi
Paduan baja panas 4140 nganti 870 oC - 900 oC, tahan nganti suhu seragam ing saindhenging bagean, rendhem nganti 10 - 15 menit lan adhem ing hawa sing tenang.
- Tempering
Re-heat baja kelas 4140 nganti 550 oC - 700 oC kaya sing dibutuhake, tahan nganti suhu seragam ing saindhenging bagean, rendhem 1 jam saben 25 mm bagean, lan adhem ing udara sing isih ana.
7. Pengerasan Baja Paduan AISI 4140
AISI alloy 4140 baja bar, piring lan kothak bisa hardened dening kadhemen digunakake, utawa dadi panas lan quenching.
Baja paduan SAE 4140 biasane disedhiyakake siap digawe panas nganti kekerasan ing 18-22 HRC. Yen perawatan panas luwih dibutuhake, banjur panas nganti 840 oC - 875 oC, tahan nganti suhu seragam ing saindhenging bagean, rendhem kanggo 10 - 15 menit saben bagean 25 mm, lan quench ing lenga, banyu, utawa polimer sing dibutuhake.
8. Aplikasi saka AISI alloy babak 4140 bar baja
ASTM alloy 4140 bar baja, bahan warata utawa piring bisa digunakake kanggo macem-macem aplikasi ing ngendi kateguhan lan resistensi nyandhang sing luwih gedhe dibutuhake kanggo tingkat karbon sing luwih murah.
