They are used for machinery parts in all machinery production areas. These plates are difficult for welding in most cases. They are supplied in soft annealed (+A) or normalized (+N) condition according to the following table. Products of these plates are further processed with heat treatment (usually quenching and tempering), after such treatment they obtain their typical properties, i.e. high toughness, hardness and strength.
