Process for manufacturing a clad sheet which includes an abrasion-resistant layer made of tool steel, and clad sheet obtained

摘要

A block is produced by juxtaposition and joining of at least one plate made of tool steel and of at least one plate made from mild steel. The block is hot rolled and then it is cooled to a temperature below 200 DEG C. The rolled block is tempered at a temperature above 450 DEG C. after cooling. The clad sheet obtained includes a layer made of tool steel having a tempered martensitic structure and containing primary carbides and a fine dispersion of secondary carbides.
