Nickel Special Alloy Inconel 690 Pipe Nickel Special Alloy Pipe Inconel 690 Pipe

Product Description
The Inconel 690 alloy has excellent resistance to intercrystalline corrosion and intercrystalline stress corrosion cracking, and is mainly used for heat transfer tube materials of steam generator in pressurized water reactor nuclear power plant. The Inconel 690 alloy, which is used as a heat transfer tube for steam generators at pressurized water reactors, has not been reported to have been damaged since it was put into use in the 1990s.

Inconel 690 process performance and requirements:
1..the alloy has good thermal processing performance, steel ingot forging heating temperature 1343 °C ~ 1377 °C.2.The average grain size of the alloy is closely related to the deformation degree and final forging temperature.3.The alloy has good welding performance, can be connected by various methods such as original arc welding, argon arc welding, resistance welding and brazing welding, large or complex welding structure parts should be annealed at 870 °C after soldering to eliminate welding stress.4. The alloy must be processed after the heat treatment, due to the hardening of the material, it is advisable to use the low cutting speed and reentry knife than the processing of the low alloy standard austenitic stainless steel to process, before the car into the cold hardened surface below.
