1. SKD61 steel round bar (Diameter 190 mm - 280 mm) steel grade

SKD61 steel is a steel grade according to JIS standards of Japan. SKD61 steel is a hot work tool steel with good balance of strength, ductility and heat resistance.
SKD61 steel is often used for hot stamping or pressure casting of aluminum and zinc because of its good machinability with little deformation after heat treatment.
Steel grade equivalent to SKD61:
- H13 steel grades by AISI manufacturer according to American standards.
- Grade 2344 steel by DIN manufacturer according to German standards.
- DAC steel grade by HITACHI manufacturer according to Japanese standards.

2. SKD61 steel characteristics

With Isotropic Technology, SKD61 steel becomes more durable and isotropic increasing the lifetime and stability of precision molds.
