スチール用の耐摩耗性コーティング
鋼用の耐摩耗性コーティング provide 例外的な硬度, 耐摩耗性, そして靭性, making them suitable for extreme industrial environments. の組み合わせ alloy composition, heat treatment, and surface hardfacing ensures that steel plates can endure 重い衝撃, sliding wear, and high-load operations, while available specifications and thicknesses allow for custom solutions in mining, 工事, and material handling equipment.
- 説明
鋼用の耐摩耗性コーティング are essential for industrial applications where 摩耗, インパクト, そして滑り摩耗 are common. These coatings are often applied via 硬化仕上げ, alloy overlays, or specialized steel plates to provide superior durability.
1. Composition of Wear-Resistant Steel Plates
High-performance wear-resistant steel plates typically consist of:
| 要素 | コンテンツ (%) | 関数 |
|---|---|---|
| 炭素 (C) | 0.25-0.50 | Forms carbides, increases hardness and wear resistance |
| クロム (Cr) | 1.0–3.0 | Enhances surface hardness and corrosion resistance |
| マンガン (ん) | 0.5-1.5 | Improves toughness and work-hardening capacity |
| ニッケル (で) | 0.3-1.0 | Increases impact resistance and toughness |
| モリブデン (モー) | 0.1–0.5 | Improves high-temperature hardness and strength |
| Tungsten / バナジウム (W/V) | 0.05-0.3 | Forms ultra-hard carbides, enhances abrasion resistance |
These alloying elements, combined with specialized surface treatments or hardfacing, create a durable wear-resistant coating over a steel substrate.
2. 機械的性質
Wear-resistant steel plates exhibit the following typical mechanical properties:
| 財産 | Value |
|---|---|
| ブリネル硬度 (HB) | 400–500HB |
| Rockwell Hardness (HRC) | ~45–50 HRC |
| 降伏強さ (MPa) | 1000–1200MPa |
| 抗張力 (MPa) | 1300–1500MPa |
| 伸長 (%) | 10–15% |
