Alloy404Uses of alloys：

HuaNickel Alloy404 alloy is mainly used in chemical equipment, petrochemical industry and marine development and other fields, can be used to manufacture various heat exchange equipment, boiler feed water heaters, petroleum and chemical pipelines, vessels, towers, tanks, valves, pumps, reactors, shafts, etc.

Alloy404Process performance：

Welding process: Alloy404 alloy can be joined by using appropriate welding methods and equipment, such as TIG (tungsten electrode inert gas welding), MIG (gas metal reactive welding), arc welding, etc.

Heat treatment: Common heat treatment methods include solution treatment and aging treatment. Solution treatment improves the plasticity and machinability of the alloy by heating it to solution temperature and then cooling it to room temperature. Aging treatment can improve the strength and corrosion resistance of the alloy by keeping the temperature at the right temperature for a long time.
