NS3403Alloy properties：

Excellent corrosion resistance: It can show good corrosion resistance in a variety of corrosive environments.

Good oxidation resistance: It can resist oxidation in high temperature environments.

NS3403Uses of alloys：

It is used in the manufacture of chemical equipment, oil and gas extraction and processing equipment, offshore engineering equipment, and certain components in the aerospace field.

NS3403Process performance：

Heat treatment: solution treatment: the alloying elements in the alloy are completely dissolved in the matrix to form a uniform solid solution. The temperature is generally between 1050°C and 1150°C.

Aging treatment: The precipitated phase in the solid solution is formed through aging treatment, so as to improve the strength and hardness of the material.
