At Solid Foundry, we specialize in producing high-chrome white iron castings based on the ASTM A532 material system. To meet the requirements of more demanding working conditions, we have also expanded our alloy range beyond standard ASTM A532 grades, developing customized materials for applications where conventional high-chrome irons may not provide sufficient performance.
High-chrome white iron is a group of wear-resistant alloys in which high-hardness carbides are distributed throughout a high-strength matrix, usually with a martensitic structure. During abrasive service, these hard carbides protect the matrix from wear. At the same time, the strong matrix firmly supports the carbides, helping prevent them from breaking away or peeling off during operation.
Because of this special microstructure, high-chromium cast iron provides excellent abrasion resistance in severe working environments, including mining, milling, mineral processing, earthmoving, cement, and general manufacturing industries.
At Solid Foundry, we can engineer high-chrome castings with chromium content from 11% to 35% and carbon content from 2.0% to 3.6% by weight, depending on the application requirements. Based on your drawings, working conditions, and field feedback, we can help select or develop a suitable alloy to improve wear life, maximize equipment run time, and reduce unplanned downtime.
Our regular high-chrome alloy grades are listed below. You can choose one or more materials according to the specific application and wear conditions of your parts.
