Wear Resistant Materials

SUPRA™ HT – AR500 BHN, Modified Analysis Wear Plate

Supra HT is produced by controlled analysis, alloy enrichment, micro melt practice, and thermal conditioning. This is a special chemistry formable product produced to maximum hardness levels.

Supra HT is produced in small electric furnaces with ladle degassing and refining. Ladle refining desulfurizes, and metal slag stirring frees unwanted gases. Micro melt practice and alloy ribbon enrichment means ideal control of analysis and physical properties. Hi-Tech rolling procedures mean closer thickness tolerance, better plate density, and superior surface quality. All plates are descaled in the rolling and heat treating process.
