About Incoloy 800/800H/800HT Flange
Incoloy 800, 800H and 800HT flanges are nickel-iron-chromium alloys known for their superior high temperature strength and resistance to oxidation, corrosion and carburization. The 800H and 800HT versions have enhanced creep and stress rupture properties compared to the base 800 alloy, making them suitable for more demanding high temperature applications. These flanges are widely used in industries such as petrochemical, chemical, power generation and aerospace.
Efficiency leap Precision and stability
Adopting high-performance integrated joints,the CRA series can increase the tempo by 25%,and the productivity can reach a new peak;the vibration suppression algorithm is upgraded to achieve a good anti-shaking effect;the full-parameter DH compensation algorithm and TrueMotion algorithm are supported,and the absolute positioning accuracy is 0.2 ~ 0.4 mm under the change of attitude movement,and the curved motion is precise and stable.
