Gr9 bars puas siv tau rau kev siv hydraulic tubing?
Yog, Gr9 yognyiam cov khoomrau aircraft hydraulic tubing tshuab. Bars yog siv los tsim:
Hydraulic fittings thiab couplings
Tube kawg formings
Connector lub cev
Manifold Cheebtsam
Rau tubing nws tus kheej, peb muab Gr9 hauv raj daim ntawv rau AMS 4943 / AMS 4944.
Gr9 tuav puas tuaj yeem kho cua sov kom muaj zog dua?
Yog lawm, Gr9 tuaj yeem kho tau thiab muaj hnub nyoog kom ua tiav lub zog siab dua:
Kev daws teeb meem: 900-940 degree, dej quench
Hnub nyoog: 480-540℃rau 4-8 teev, cua txias
Lub zog ua haujlwm: Tensile mus txog 750-800 MPa
Txawm li cas los xij, qhov no txo qis formability thiab tsis tshua muaj ntau dua li siv Gr5 rau siab - daim ntawv thov zog.
