In this work, experimental studies were carried out to obtain bimetallic pipes and rods using explosion welding and hot deformation. The cladding layer was made of 08Cr18Ni10Ti stainless steel. It was found that explosion welding provides high-quality adhesion of the bimetal layers. Subsequent hot plastic deformation did not affect the ratio of the component layer thicknesses and the quality of the welded joint, which is confirmed by studies of the microstructure and mechanical tests of samples for flattening. Based on the results obtained, a combined technology for the production of bimetallic pipes and rods with a combination of layers of steel 20 + 08Cr18Ni10Ti was developed and tested.
