Deformation Inconel625

Deformed Inconel 625 refers to a type of alloy that can be hot and cold deformed and has an operating temperature range of -253 to 1320 ° C. It has good mechanical properties and comprehensive strength and toughness indicators, and has high oxidation and corrosion resistance. According to its heat treatment process, it can be divided into solid solution strengthening alloy and aging strengthening alloy.
1. Solid solution strengthening alloy
The use temperature range is 900 ～ 1300 ℃, and the highest anti-oxidation temperature is 1320 ℃. For example, the GH128 alloy has a room temperature tensile strength of 850 MPa and a yield strength of 350 MPa; a tensile strength of 1000 ℃ is 140 MPa, an elongation of 85%, and a 1000 ℃ and 30 MPa stress has a life span of 200 hours and an elongation of 40%. Solid solution alloys are generally used to make aviation, aerospace engine combustion chambers, casings and other components.
2. Aging strengthened alloy
The use temperature is -253 ~ 950 ℃, generally used in the manufacture of aerospace engines turbine disks and blades and other structural parts. The working temperature of the alloy used to make the turbine disk is -253 ～ 700 ℃, which requires good high and low temperature strength and fatigue resistance. For example: GH4169 alloy, the highest yield strength at 650 ℃ reaches 1000MPa; the alloy temperature of the blade can reach 950 ℃, for example: GH220 alloy, the tensile strength at 950 ℃ is 490 MPa, the endurance life of 940 ℃, 200MPa is more than 40 hours.
Deformed Inconel625 mainly provides structural forgings, cakes, rings, bars, plates, pipes, strips and wires for the aerospace, aviation, nuclear energy, and petroleum civil industries.
Casting Inconel625
Casting Inconel625 refers to a type of Inconel625 that can or can only be formed by casting. Its main features are:
1. Has a wider composition range. Because it is not necessary to take into account its deformation processing performance, the design of the alloy can focus on optimizing its performance. For nickel-based Inconel 625, the composition can be adjusted so that the γ ‘content reaches 60% or higher, so that the alloy can still maintain excellent performance at a temperature up to 85% of the melting point of the alloy.
2. Has a wider application field. Due to the special advantages of the casting method, Inconel625 castings with any complex structure and shape can be designed and manufactured in near-net shape or without margin according to the use needs of the parts.
