- N-gun ja ai:Chromium-Molybdenum n-gang gaw n-gang hpe sung sung ngang kang hkra galaw ya ai majaw, n-gang kaba ni hta pyi n-gun maren sha nga lu ai (ga shadawn, 500mm diameter n-gang ni).
- Grai kaja ai Fatigue N-gun:Mawdaw axle hte drill collar zawn re ai, cyclical loads hte vibration ni hpe hkrum sha nga ai daw ni a matu kaja dik htum re.
- Shawng-hkum tsup ai (QT) nga ai:Anhte gaw 4140 hpe stock galaw da ai.28-32 HRC hpe n-gun ja hkra galaw da aimasa. Ndai hku galaw ai gaw, post-machining heat treatment a manu hte aten hpe yeng seng kau ya nna, hpang jahtum daw hpe n hkra hkra galaw ya ai.
- Kaja ai Mashin galaw lu ai atsam:Annealed (sh) pre-hardened masa hta, ntsa lam kaja ai hte kaja hkra galaw ai.
- Hkrum hkra ai lam ngang kang ai:1045 zawn re ai carbon steel hta grau kaja ai, shock loads npu hta daw mat ai hpe ninghkap lu ai.

FAQ
Q1: 4140 hte 42CrMo lapran hpa shai ai kun?
A1: Shanhte gaw grai bung ai. 4140 ngu ai gaw American (AISI) masat masa rai nna, 42CrMo gaw Miwa (GB) masat masa rai nga ai. Shanhte a chemical nsam hte jak rung atsam ni gaw engineering sumla ni hta 99% shada da galai shai mai ai.
Q2: "4140 QT" ngu ai lachyum gaw hpa rai ta?
A2: QT ngu ai gaw Quenched hte Tempered ngu ai lachyum re. Lachyum gaw, n-gang hpe n-gun ja ai hku 28-32 HRC (280-320 HB) daram n-gun ja hkra galaw ngut sai. Dai hpe n-gun n rawng ai sha, ngut sai daw langai mi de direct machine hte galaw mai ai. Ndai gaw anhte a grau nna htuk manu ai delivery masa re.
Q3: 4140 steel hpe weld galaw mai ai kun?
A3: Rai na re, raitim sadi maja ra ai. 4140 hpe katsi ai hku weld galaw yang, n-gun ja ai majaw, n-gun yawm mat chye ai. Dai hpe n-gun n rawng shi yang (approx. 200-300℃daram ) shawng katsi shangun nna, dai hpang loi loi hte katsi shangun ra ai. Hydrogen n law ai -electrode ni hpe lang u.
Q4: 4140 gaw 1045 steel hta grau n-gun ja ai kun?
A4: Rai sai, ahkyak ai hku nna. 4140 gaw 1045 carbon steel. 4140 hta grau nna n-gun ja ai tensile n-gun, yield n-gun, hte n-gun yawm ai hpe hkam sharang lu ai hta grau nna 1045 hpe n-gun n rawng ai sha, n-gun n rawng ai sha, n-gun n rawng ai (sh) daw mat ai hpe pat shingdang lu ai.
