Hardox 400 vs Dillidur 400

General Product Description
The versatile steel that resists wear and abrasion. Hardox 400 is an abrasion-resistant steel with a nominal hardness of 400 HBW. Hardox 400 is a versatile wear-resistant steel. As a result of its high
toughness, good bendability and weldability, this steel can be used in structures with moderate wear.		  
 
 		 Material data sheet, Edition April 2016
DILLIDUR 400 is a wear resistant steel with a nominal hardness of 400 HBW in delivery condition ex works.
DILLIDUR 400 is preferentially used by the customers where elevated resistance to wear is required together
with good workability and especially good weldability.
Examples of application: earth moving and loading machines, dredgers, skip cars, conveying plants, trucks,
cutting edges, knives and breakers, waste elimination and recycling plants.
