Hardox 400 vs Hardox 450
| Hardox 400 | vs | Hardox 450 | |||||
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. |
|
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 | |||||
