Thank You for Your Attention on Beiye!
Mar-M246 is a kind of Nickel-based casting alloy which is strengthen by the precipitation phase. It has high persistent strength and creep rupture strength at 650-1040℃which simultaneously has good anti-oxidation property and be good at casting complex shape castings as well as making a single turbo.
