Ultra 500 is an abrasion-resistant alloy-steel plate that is produced to a fully killed fine-grain practice. It is vacuum degassed and ladle de-sulphurized. This grade is quenched and tempered, with plates produced being one-half of the ASTM A6 flatness tolerance throughout the thickness range. The hardness range for this product is 477 BHN - 534 BHN and, like Ultra 400, it combines through hardness and toughness benefits with superior flame-cutting, forming and welding characteristics. Ultra 500 is typically used for the fabrication of mining and construction equipment or, where the application demands superior hardness, to our Ultra 400 plate. Specifications include:
- Thicknesses of ¼" through 2"
- Standard stock size of 96" by 288"
