AISI M50 high speed tool steel balls provide excellent mechanical properties and shock resistance. These Tool Stainless Steel Balls have a higher hardness than the usual AISI S2 balls and also have a better wear and tear resistance. Due to the presence of Chromium the corrosion resistance of this steel is better than AISI S2 balls.
Applications :
- Oil and gas industry
- Aerospace
- Applications where temperatures are at the highest
