💡 Practical Difference in Use
Use Rockstar 400 when: a balance of hardness, strength, and good formability is needed for moderate to heavy wear applications.
→ Example: truck bodies, liners, buckets, feed chutes.
Use Rockstar 450 when: improved impact toughness and higher abrasion resistance are required for harsher environments.
→ Example: mining liners, dump truck bodies, crushers, hoppers.
Use Rockstar 500 when: extreme hardness and maximum abrasion resistance are essential for severe wear conditions.
→ Example: excavator buckets, loader blades, cutting edges, screens.
