Hardox 450 vs Hardox 500  

General Product Description

  

The most popular abrasion-resistant steel with excellent structural properties. Hardox 450 is an abrasion-resistant steel with a nominal hardness of 450 HBW. Hardox 450 combines good bendability and weldability. The products can be used in many different components and structures that are subject to wear. Hardox 450, with an extra 50 Brinell hardness over our 400 grade, provides better dent and abrasion resistance as well as longer wear life, so you can achieve even greater savings

  
 
 

The bendable, weldable and highly abrasion-resistant steel. Hardox 500 is a bendable and weldable abrasion-resistant steel with a nominal hardness of 500
HBW. Suitable for applications that demand higher wear resistance. Hardox 500 increases payload and service life while maintaining good processability
and toughness.
