AR400F / Hardox® 450 Steel Plate

Alro stocks AR-400F and Hardox® 450 plate. AR-400F is a through-hardened abrasion resistant plate designed to satisfy the demand for a grade of steel that can give prolonged service life where abrasion is the primary cause of failure.  AR400F is quenched and tempered through hardened wear resistant grades of abrasion resistant steel plate used for high impact and abrasion resistance. AR400F has a minimum Brinnel hardness of 360. AR400F is produced through austentizing, water quenching, and tempering.

Hardox® 450 is an abrasion-resistant brand with a hardness of 450 bhn. This brand of abrasion resistant plate is intended for higher, impact, wear applications where cold-bending and very good weldability are beneficial.Hardox® 450 is a quenched and tempered produced plate that is used in Dump bodies, crushers, feeders, cutter edges, buckets, etc.
