NS343Alloy 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.
NS343Uses 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.
NS343Process 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.
