Microstructure-Texture-Mechanical Properties in Hot

Feb 16, 2016 · The current production process of a ring is mainly composed of pouring ingot, cogging, cutting, upsetting, punching, hot ring rolling, and heat treatment. Before hot ring rolling (HRR), the starting material is as-forged state (Ref 1, 2). The existing process has some disadvantages, such as multi-pass heating, materials and energy wasting, and Microstructure evolution and mechanical anisotropy of M50 Jun 10, 2020 · 1. Introduction. Aeroengine bearings are required to operate at 300350 °C. M50 high-temperature bearing steel has been widely used to satisfy this requirement.1, 2 M50 is a fully hardened martensitic steel commonly used in aeroengine bearings, as it has excellent wear resistance, dimensional stability, and high Vickers hardness of 800 even at 300 °C. 3 The excellent properties of Aisi 8620 Seamless Cold Drawn Steel Tube Hydraulic Steel ASTM A519 8620 seamless steel pipe/tube is widely used in the mechanical treatment field, petrochemical industry, transport and construction field; A519 8620 used in ordinary structural purposes and mechanic structural purposes, for example 8620 material used in construction field, fulcrum bearing etc; The transportation of fluids in the Round Cold Finished Bar Dia 2-100 Mm 1045 / S45C / S45K 1045 / S45C / S45K cold drawn bar, cold finished steel bar for mechnical purpose, Dia 2-100 mm Application.
