InconelX750/alloyX750 alloy is a precipitation hardening alloy with corrosion resistance, oxidation resistance and high strength. It is mainly a nickel-based superalloy strengthened by γ "phase aging. The alloy has good corrosion resistance and oxidation resistance below 800℃, high strength below 800℃, good creep resistance below 700℃ and excellent creep resistance below 540℃. The alloy is pure austenite in solid solution.
Inconel x750/ Alloy X750? There are many products produced by alloys, and their mechanical properties are different due to different heat treatments. Inconel x750/ Alloy X750? Features and uses: The alloy is mainly used to manufacture the ring, structural parts and bolts of aero-engines that require high strength and corrosion resistance when working below 800℃, and the parts that require low stress and anti-relaxation when working below 540℃, such as plane springs and helical springs, circumferential helical springs, helical compression springs, spring circlips and sealing rings. . It can also be used to make parts, such as turbine blades of steam turbines. The alloy can be welded after solution treatment. The heat treatment of parts should be carried out in neutral or reducing gas without sulfur to avoid solidification. Parts should avoid cold and hot treatment at 870-650 degrees. For parts with large planting surface, they should be cooled in the air after solution treatment to prevent cracks.
Inconel x750/ Alloy X750? The information of the alloy is as follows: implementation standards: UNS, ASTM, AISI, DIN, GB/T 14992, corresponding grades: national standard grades GH4 145, GH 145, 0Cr15NI70T3LNB, and American standard grades. Inconel x750/ Alloy X750? Density 8.25, non-magnetic.
