POSTALLOY®
RailTuff
POSTALLOY® RailTuff is a build-up electrode in the machinable range of hardness providing wear resistance that is far superior to low and medium carbon steel and low alloy steels.

Deposits are extremely tough and have a high resistance to impact and deformation and are not subject to spalling or roll-over. In addition, deposits are dense, crack-free and porosity-free.
