Description |
|
age hardening |
is heated in the range of 500-600°C, and then slowly cooled to improve the strength and hardness of the alloy. |
machining and welding
·Cold working: suitable for cold drawing and cold rolling, which can increase strength.
·Hot processing: should be carried out between 870-1200°C.
·welding: TIG and MIG welding can be used, and annealing treatment is required after welding.
Application
·Offshore engineering: Equipment and components used to resist seawater corrosion.
·Petroleum industry: downhole tools, valves and pump components.
·chemical equipment: corrosion-resistant pumps, valves and heat exchangers.
·Aerospace: Used for parts that require high strength and corrosion resistance.
Monel K500 alloys are available in different shapes and sizes, including plates, bars, wires and forgings.
