HS A4 Cold Work Die Steel

As modified cold work tool steel, HS A4 is improved high-toughness impact-resistant cold work die steel. It has fine and uniform ledeburite carbides, high toughness and impact resistance, and is not easy to crack when used for molds with complex shapes. The steel is a new generation of high-strength, high-impact cold-work die steel.
