A method for manufacturing clad metal sheets with a wear-resistant layer of tool steel

摘要

Is a block, by juxtaposing and assembly of at least one plate made of tool steel and of at least one plate made of soft steel. It is hot rolled block is then cooled to a temperature lower than 200 degrees c, a tempering of the rolled block at a temperature higher than 450 degrees c, after the cooling. The clad sheet obtained has a layer made of tool steel having a tempered martensitic structure and enclosing the primary carbides and a fine dispersion of secondary carbides.
