Caratteristiche
1. DIN 1.2343 is a 5% chromium hot work steel that is characterized by excellent impact toughness. It contains less vanadium than DIN 1.2344. This provides for the higher toughness, with some reduction in wear resistance and temper resistance.
2. Deep-hardening, air-hardening steel that exhibits minimal size change during heat treatment.
3. Good resistance to thermal fatigue cracking (heat checking) and excellent resistance to gross cracking and thermal shock when water cooled in service.

Applicazioni
Heavy duty hot work tools and dies, mainly for light alloy processing: mandrels, dies, and containers for metal tube and rod extrusion; hot extrusion equipment; tools and dies for the manufacture of hollow bodies, screws, rivets, nuts and bolts. Die casting equipment, forming dies, die inserts, hot shear blades, and plastic mould dies.
