METHOD OF MANUFACTURE OF THE MULTILAYERED STAINLESS METAL PRODUCTS Russian patent published in 2006 - IPC B32B15/18 B23K20/02 

FIELD: ferrous metallurgy; methods of production of the multilayered stainless metal products.

SUBSTANCE: the invention is pertaining to the field of ferrous metallurgy, in particular, to the method of production of the multilayered stainless metal products and may be used at manufacture of the multilayered metal products with a tracery on their surface natural for the damask steel, in particular, the knives, blades and other cutting tools. A pack composed out of the stainless steel plates is placed in the steel container, seal it and conduct the hammering and-or rolling of the plates together with the container in two stages at the preset temperature and the degree of the metal the deformation. Then they remove the container and conduct the emollient heat treatment and cutting of the multilayered sheets into the multilayered workpieces. Create the distorted form of all or some layers of the workpiece. Exercise their flattening by hammering or rolling of the workpieces with the degree of deformation till production of the multilayered products of 1.5-15 mm thick. For the purpose to obtain the necessary hardness and strength conduct the hardening and tempering of the products with the subsequent polishing and detection on the products polished surfaces of the traceries similar to the pattern on the damask steel. At that the invention ensures the high mechanical properties of the whole volume of the metal product, and especially the high firmness and resistibility against bluntness of the sharp cutting edges of the blades.

EFFECT: the invention ensures the high mechanical properties of the whole volume of the metal product, especially the high firmness and resistibility against bluntness of the sharp cutting edges of the blades.
