| Workability by cutting |
For machining, including diamond processing, it is preferable to use negativnoe or hardened state. |
| Pressure treatment |
To all kinds of cold treatment. |
| Features of heat treatment |
Low-temperature annealing leads to a significant increase of hardness, while reducing ductility. This can be used to improve the wear resistance of products. |
| Casting |
When the casting alloy must be melted under vacuum and poured under a protective atmosphere. |
| Soldering |
Alloy well soldered and recommended for the manufacture of products coated with enamel. |
