Description

AMPCO® 22 is a duplex structure alloy of approx. 50 % of each phase - gamma 2 and beta. It is remarkable because of its hardness, its excellent compression and wear resistance and by its sliding properties. As the elongation of the material is very low, thin sections should be avoided and the material should be well backed up.

Application areas

The field of service of AMPCO® 22, with few exceptions, is limited to forming and/or drawing stainless steel, especially when runs are long or gauge is heavy and it is essential that tolerances be maintained.
