1. High temperature strength, thermal stability, environmental resistance
230 alloy containing nickel, chromium, tungsten and molybdenum, with excellent high temperature strength, even long exposure to 1149 ° C high temperature environment also has outstanding antioxidant properties, especially nitriding environment, there is a very good long-term thermal stability The The material can be machined, molded and cast. Compared to other superalloys, the 230 alloy has a lower thermal expansion characteristic and is able to coarsen the particles for a long time under high temperature conditions.
Easy to process
230 alloy forming and welding performance is good. Forging, if the high temperature for a long time so that the entire workpiece to 1177 ° C, but also hot processing. Due to the good ductility, the 230 alloy can be cold formed. Whether hot or cold, the finished parts are annealed and cooled quickly to restore the best performance of the material. The alloy can be welded in a variety of ways, including GTAW (tungsten inert gas shielded welding), GMAW (metal pole gas shielded welding) and resistance welding.
3. Heat treatment
230 alloy supply status is usually forged solid solution. The solution temperature range is 1177-1246 ° C and then quickly cooled or water quenched to achieve optimum performance.
If the annealing temperature is lower than the solution temperature, carbonization will occur, which will affect the strength and ductility of the 230 alloy.
4. Casting
230 alloy can be used for traditional sand casting or vacuum casting. It is recommended to use the upper limit of the silicon liquid level in the specification to improve fluidity. According to the performance requirements, casting parts can use the casting state and solid solution state.
5. Multiple supply shapes
230 alloy supply shape of thick plate, sheet, strip, foil, block material, round bar, wire, welding products, pipe material
6. Application
230 alloy excellent comprehensive performance in the aviation and energy industry can be widely used, such as combustion chamber, relay signal, flame stabilizer, thermocouple protective cover, and other gas turbine parts. In the chemical industry, with 230 alloy production catalyst grid into the nitrogen burner, and high-strength thermocouple protection casing, high temperature heat exchangers, pipes, high temperature bellows and so on.
In the industrial heating industry, 230 alloy has a variety of applications, such as manufacturing furnace room, fixture, combustion chamber flame cover, heat exchanger shell, damper, nitriding furnace shell, heat treatment with the basket, grille, tray The
