Abstract
Investigation results are presented on structure and wear resistance of metal deposited by using flux-cored strips and having chemical composition of the low-carbon steel type with differing manganese content. The possibility of improving wear resistance of the deposited metal due to subsequent heat and thermochemical treatments is studied. It is shown that achievement of the optimal amount of meta-stable austenite in structure leads to improvement of wear resistance of the deposited metal.
