DH31-EX
High strength, tough and high heat check resistance hot work die steel.
QUICK NAV
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.
Applications include:
Aluminum Die Cast Dies
Aluminum Die Cast Parts
Hot Forging Dies
Hot Pressing Dies
Aluminum Extrusion Dies
- High hardenability
High toughness is obtained even in large size die. - High strength
High softening resistance at elevated temperature contributes to high wear resistance. - High toughness
