Alloy C4 / 2.4610

Due to the combination of chromium with high molybdenum content receives 2.4610 exceptional resistance to a variety of chemical media such as contaminated, reducing mineral acids, chlorides and organic as well as inorganic chloride contaminated media. Due to the particular chemical composition of the alloy C4 has a good structural stability and high resistance to awareness.
