Choose our Xtralloy 24% manganese steel castings for fewer changeouts and lower cost per ton

Field proven since 1988

Columbia Steel’s 24% manganese steel, Xtralloy, became a production alloy in 1988 and has been widely accepted by customers in aggregate production and ore processing as a way to reduce downtime costs.

High alloy and quality

Xtralloy is significantly higher in carbon and manganese content than conventional Hadfield’s manganese steel, resulting in excellent wear resistance with reliability. The extra effort and skill required to manufacture it have proven worthwhile, as Xtralloy continues to be the crusher operators’ premium wear material of choice.

Xtralloy High Manganese Steel Castings

Solid performance data

Starting in 1989, we began recording Xtralloy’s progress in the field, noting significant wear life increases over previous crusher parts of various other alloys and origins. The reliability of Columbia Steel’s Xtralloy parts has always been excellent.

User benefits

Based on data and comments provided by our customers world-wide, Xtralloy offers the following benefits in many crushing applications:

  • Longer wear life
  • Savings in labor, backing material and downtime
  • Crusher production maintained throughout liner life
  • Lower cost per ton of material crushed


Xtralloy shows its best performance improvements when crushing tough materials. Since 1988, our Product Engineers have gained extensive experience with alloy applications in all types of crushing conditions, so they are able to estimate Xtralloy performance.

Like no other alloy on the market, Xtralloy can be used for parts with thick sections while maintaining high manganese and carbon levels. It uniquely meets the need for heavy-duty premium manganese steel wear parts, such as large cone and primary gyratory liners. We can also improve the wear life ratios of opposing wear parts by using Xtralloy and standard manganese alloys.
