AISI H-12 / DIN 1.606
H12 hot work Die Steel could be a five-hitter Cr, general hot work steel that is characterized by glorious impact toughness. It contains less vanadium than the widely-used H13 hot work tool steel, and also the tungsten content provides higher temper resistance. it has smart resistance to thermal fatigue cracking (heat checking) and excellent resistance to gross cracking and thermal shock once water cooled in commission.
H12 hot work tool steel is usually recommended for warm tooling applications wherever most resistance to cracking is needed. Such applications embrace hot punches, die casting dies, shaping dies, hot shear blades, hot gripper dies, and extrusion tooling.
