NS112Alloy properties：

Excellent corrosion resistance in aqueous media at very high temperatures up to 500°C; Very good resistance to stress corrosion; Very good processability.

NS112Uses of alloys：

It is widely used in chemical, petroleum, pharmaceutical and sewage treatment fields.

NS112Process performance：

Welding process: NS112 can be welded by common welding methods, such as argon arc welding (TIG), arc welding (MIG), etc.

Heat treatment:

Solution treatment: Solution treatment is mainly used to dissolve alloying elements into the matrix, improve the uniformity of the alloy, and prepare for subsequent aging treatment. Aging treatment: Through aging treatment, the precipitated phase in the alloy is refined and evenly distributed, thereby improving the strength and hardness of the alloy.
