Inconel 600 alloy heat exchanger tube is a nickel-chromium-iron based solid solution strengthened alloy with good high temperature corrosion resistance and oxidation resistance, excellent cold and hot processing and welding process performance, and satisfactory thermal strength and high plasticity below 700℃. The alloy can be strengthened by cold working, and can also be connected by resistance welding, fusion welding or brazing.

inconel 600 Heat exchange tubes for power plants Hot working
1. The hot working temperature range is 1200℃～900℃, and the cooling method is water quenching or rapid air cooling.
2. To obtain the best corrosion resistance and suitable crystal structure, heat treatment is required after hot working.
3. The material can be directly sent to the heated furnace.
inconel 600 condenser tube cold working
1. The cold working material should be annealed or solution heat treated. The work hardening rate of 600 alloy is close to that of austenitic stainless steel, so similar processing equipment can be selected.
2. Intermediate annealing should be performed during the cold working process.
3. When the cold working amount is greater than 5%, the workpiece needs to be solution treated.
4. To reduce material wear, the mold should be selected from alloy tool steel, cemented carbide or cast steel.
