Rockstar 450 Plates – High Hardness Abrasion Resistant Steel
Rockstar 450 Plates are part of a range of high-hardness, low-alloy martensitic steel designed for superior abrasion resistance. Achieving their hardness through an intensive water quenching and tempering process, Rockstar plates offer three nominal hardness levels: 400, 450, and 500 BHN. These plates are engineered for high hardness, toughness, and good formability, making them ideal for demanding wear applications.
Rockstar 450 Plate Grade Designation:
Rockstar Plates are categorized by hardness levels for easy selection based on performance requirements.
| Product Category | Hardness Level |
|---|---|
| Rockstar 400 | 360-430 BHN |
| Rockstar 450 | 425-475 BHN |
| Rockstar 500 | 450-540 BHN |
Available Sizes for Rockstar Plates:
A variety of sizes are available to accommodate different industrial needs, ensuring flexibility in application.
| Product Category | Thickness | Size (Width x Length) |
|---|---|---|
| Rockstar 400 | 6 – 80 mm | 2000 mm / 2500 mm x 6000 / 12000 mm |
