HS200 vs HARDOX | Chromium Carbide Overlay Plate vs Q&T Steel – Which Performs Better?
HS200 vs HARDOX: Choosing the Right Wear Plate
Longer Wear Life, Smarter Cost – HISAN HS200 vs HARDOX
Introduction
In high-abrasion and high-impact industries, choosing the right wear plate is crucial. HISAN often receives questions comparing our HS200 Chromium Carbide Overlay (CCO) plate with the well-known quenched & tempered (Q&T) HARDOX steel. HS200 is a bimetallic wear plate with a hardfaced chromium carbide overlay welded onto a mild steel base. HARDOX, by contrast, is a well known wear-resistant steel that relies on its homogeneous hardness throughout.This article breaks down their differences to guide you in making the best choice.
Material and Structure Comparison
| Feature | HS200 (HISAN) | HARDOX (SSAB) |
|---|---|---|
| Plate Type | Chromium carbide overlay on mild steel | Quenched & tempered steel plate |
| Structure | Bimetallic (hardfaced layer + mild steel) | Monolithic homogeneous steel |
| Surface Hardness | 58–63 HRC (up to 700+ HV) | 450–600 HBW (grade-dependent) |
| Thickness Range | 6+4mm to 12+50mm, customizable | 4mm–80mm |
| Surface Finish | Original with welding beads ,Smooth or polished overlay available | Matte rolled surface |
Performance Overview
| Aspect | HS200 | HARDOX |
|---|---|---|
| Sliding Abrasion | ★★★★★ Excellent | ★★★★ Good |
| Impact Resistance | ★★★ Moderate | ★★★★★ Excellent |
| Service Life | 5× longer in wear zones | Shorter in sliding wear |
| Cost Efficiency | Lower total cost per wear cycle | Higher material cost |
| Maintenance | Weldable patches; low replacement cost | Full plate replacement |
Conclusion
Both HS200 and HARDOX have their strengths. The best choice depends on your application’s wear mode. If your priority is resistance to sliding abrasion, especially from materials like ash, sand, cement, or ore slurry, HS200 CCO wear plates outperform HARDOX in both service life and cost per use. For applications with high impact, HARDOX remains a solid choice. For superior performance against abrasive wear and better long-term economy, HISAN HS200 is your trusted solution. Choose based on wear mode!
