Description
Product Description
AR450 steel plate is a type of abrasion-resistant (AR) steel that offers a good balance of toughness and wear resistance. The “450” indicates a nominal hardness of 450 Brinell, making it suitable for applications where high resistance to wear and impact is essential.
Applications:
- Mining and construction equipment
- Material handling systems
- Heavy machinery components
- Chutes, hoppers, and liners
Benefits:
- Reduces wear and tear on equipment
- Extends the lifespan of components
- This can lead to cost savings through reduced maintenance and downtime
