Alloy Grade UNS: MTEK X-45 – Non-Galling High Temp Alloy

  • Overview

    MTEK X-45 is a specialized high-temperature alloy specifically engineered to resist galling and withstand extreme thermal conditions. This alloy exhibits exceptional resistance to galling, a form of wear caused by adhesive friction between sliding surfaces, making it suitable for applications where components experience high contact pressures and relative motion. Furthermore, MTEK X-45 offers excellent heat and thermal shock resistance, allowing it to maintain its structural integrity and performance even under rapid temperature changes and exposure to extreme heat. This combination of properties makes MTEK X-45 a valuable choice for demanding applications where galling resistance and thermal stability are critical.
