Through Hardened Rollers
Hi-Hard Corporation provides several types of through hardened parts for various hot and cold processing operations. These rolls are made using 400 series stainless, medium/high carbon alloy steels, and tool steel. Hardness on these product will vary on application and are controlled through the heat treatment. The hardness on these rolls is through the thickness of the material. Rolls are manufactured as solid and fabricated designs.
- Through hardened stainless steel
- Quench and tempered rolls
- High temperature quench and tempered rolls
- Tool steel rolls
The through hardened rolls are a wide variety of carbon steel, alloy steel, stainless steel, iron, or tool steel.
