Product Description

ASSAB88,K340,DC53 Round Steel Bar


1: DC53 steel introduction

DC53 is a general purpose cold work tool steel with exceptional Toughness, Wear Resistance, Compressive Strength and Temper Resistance. Applications include:

• Punches & dies
• Draw & forum dies
• Shear blades
• Shredder knives
• Thread & form rolls
• Cold heading dies
• Mill rolls & slitters

2.DC53 chemical composition:

Grade	C	Si	Mn	Ni	Cr	Mo	W	V
DC53	1.0	1.0	0.4		8.0	2.0		0.3

 3.DC53 Characteristics:

• Higher hardness (62-64 HRc) than D2 after heat treatment.
• Twice the toughness of D2 with superior wear resistance.
• Substantially higher fatigue strength compared to D2.
• Smaller primary carbides than D2 protect the die from chipping and cracking.
• Secondary refining process (DLF) reduces impurities.
• Machines and grinds up to 40% faster than D2.
• Less residual stress after wire EDMing.
