The extra hard and tough steel for extreme wear At a nominal hardness of 600 HBW, Hardox 600 has a uniquely high impact toughness. Especially suited for extreme wear conditions, it can still be cut and welded, making it an excellent choice for high-performance applications. Hardox 600 is a Q&T martensitic wear plate for applications that demand high resistance to abrasion and wear. Delivering a hardness of 600 Brinell, it offers a unique combination of weldability, hardness and toughness. It brings a level of user-friendliness not found in many other steels designed for high wear resistance and eliminates the need to sacrifice wear resistance to enhance impact strength.
