How Are Caterpillar Steel Plate Specifications Different Than ASTM?

Caterpillar steel plate specifications often have higher tolerances for yield strength, impact toughness at low temperatures, weldability and cleanliness compared to standard commercial steel plate specifications. Since these specifications are proprietary, it is important that this type of material is sourced from an approved supplier. Doing so ensures compliance with drawing requirements, certification standards and supply chain expectations. Leeco® Steel is a Caterpillar-approved steel plate vendor that stocks a broad range of CAT specification material and offers value-added processing services including cutting, beveling and drilling, helping customers streamline procurement while receiving fully traceable material backed by mill test reports and industry-leading inventory availability.
