Corrosion Resistance

The comparative Corrosion resistance of various Weartech alloys is shown in the table. Almost all the alloys show good resistance to acetic, formic, and phosphoric acids. In all cases, actual field tests are recommended prior to alloy selection.

Finishing of Weartech Alloys

Machining: Turning, facing & boring
Tools Recommended: C-2 or Carboloy 883

Grinding: Grinding is recommended for alloys with hardnesses higher than RC 55. The alundum type of wheels is preferable. Grinding speeds of 2800-4000 ft/min are used depending on the alloy and parts. The use of coolants minimizes surface cracks.
