Looking for a reliable abrasion-resistant steel that combines durability, formability, and cost efficiency? Rockstar 400 is a proven wear plate trusted by buyers worldwide for medium to high abrasion environments. Engineered for consistent performance, Rockstar 400 delivers extended service life, reduced downtime, and excellent value—making it a smart procurement choice for industries where wear resistance directly impacts profitability.
Why Buyers Prefer Rockstar 400
Buyers choose Rockstar 400 because it offers an ideal balance between hardness and toughness. Unlike generic wear plates, this grade performs consistently in real-world conditions, helping operations maintain productivity while controlling maintenance costs. Moreover, it allows easier fabrication compared to higher hardness grades, which adds further commercial advantage.
From a buyer’s standpoint, Rockstar 400 improves lifecycle performance without increasing fabrication complexity. Consequently, it has become a preferred abrasion-resistant steel across mining, construction, and material handling sectors.
Key benefits that drive buyer preference include:
- Excellent abrasion resistance for sliding and moderate impact wear
- Nominal hardness of ~400 HBW, ensuring durability without brittleness
- Good weldability and cold forming properties
- Longer component life, reducing replacement frequency
- Cost-effective wear solution compared to higher hardness plates
- Reliable performance across varied operating conditions
As a result, Rockstar 400 delivers predictable results and long-term value for procurement teams and project managers.
Technical Specifications of Rockstar 400
A clear understanding of technical data helps buyers specify the right material with confidence. Below are the commonly supplied technical specifications of Rockstar 400.
Chemical Composition (Typical %)
- Carbon (C): 0.12 – 0.20
- Silicon (Si): 0.20 – 0.50
- Manganese (Mn): 1.00 – 1.60
- Phosphorus (P): ≤ 0.025
- Sulfur (S): ≤ 0.010
- Chromium (Cr): 0.30 – 1.00
