1. Introduction: What is S2 Powder and Why It Matters in PM
S2 powder is a high-performance powder metal (PM) material primarily used for tool manufacturing, especially in high-load, high-wear applications such as impact-grade screwdrivers, cutting tools, and dies. It is a type of alloy スチール powder with optimized hardness, toughness, and wear resistance.
In powder metallurgy (PM), S2 powder is prized for its:
- Excellent impact resistance
- High torsional strength
- 優れた耐摩耗性
- Cost-effective performance in mass production
S2 tool steel typically contains chromium, molybdenum, and vanadium, allowing it to be heat-treated to high hardness levels while maintaining toughness. The powdered form of S2 allows manufacturers to produce near-net-shape parts with minimal material waste and high consistency.
Why S2 Powder is Important for B2B Buyers:
| 特徴 | Benefit for Industrial Buyers |
|---|---|
| 高い硬度 | Ideal for tool-making and high-impact parts |
| Powder form | Enables precision PM manufacturing |
| Cost-efficient | Reduces waste and machining time |
| Scalable | Suitable for mass production |
For wholesale buyers, S2 powder offers excellent ROI when sourcing for tool manufacturing, precision components, and high-performance mechanical parts.
