1. What is Stellite Powder and Why It Matters in Modern Manufacturing
Stellite powder refers to a family of cobalt-based alloy powders engineered for superior wear resistance, corrosion resistance, and high-temperature strength. Originally developed by Haynes International, Stellite alloys have become the industry standard for hardfacing, thermal spraying, and additive manufacturing.
Key Characteristics of Stellite Powder:
- High cobalt content (typically 50–60%)
- Contains chromium, tungsten, molybdenum, and carbon
- 優れた耐摩耗性と耐食性
- Withstands temperatures above 800°C
- Suitable for laser cladding, PTA welding, HVOF spraying, and 3Dプリンティング
Why It Matters in Manufacturing:
| 特徴 | ベネフィット |
|---|---|
| High hardness (up to 60 HRC) | Extends tool life and reduces maintenance costs |
| 熱安定性 | Ideal for aerospace and power generation components |
| 耐食性 | Suitable for chemical processing and marine applications |
| 生体適合性 | Used in surgical implants and medical tools |
Stellite powder plays a crucial role in increasing the lifespan of industrial components, reducing downtime, and improving operational efficiency—key priorities for B2B buyers in manufacturing, mining, energy, and defense industries.
