DH31-EX is a hot working die steel with the best balance of strength and toughness showing the comparable softening resistance to SKD7 and twice hardenability as that of SKD61. Features High hardenability: High toughness is obtained even in large size die. High strength: High softening resistance at elevated temperature contributes to high wear High toughness: DH31-EX has higher toughness than that of SKD61. High heat check resistance: Excellent heat check resistance leads to longer life. Take a look at DH31-EX NADCA Certification here.
