INVESTIGATION OF HIGH-TEMPERATURE OXIDATION AND DECARBURIZATION OF ALLOY STEELS OF MARKS 40KHN, 34KHN1M, AND 5KHNM DURING HEATING FOR PRESSURE TREATMENT
Abstract
Alloy steel grades 40KhN, 34KhN1M, and 5KhNM are widely used for the manufacture of components and metal products for various purposes. Specifically, structural chromium-nickel alloy steel grade 40KhN is used to manufacture critical, loaded components (axles, shafts, connecting rods, gears, couplings, spindles, bolts, levers, etc.) subject to vibration and dynamic loads. These components require increased strength and toughness. Structural alloy steel grade 34KhN1M is used to manufacture similar, particularly critical, highly loaded components operating at temperatures up to 500°C. Tool die steel grade 5ХНМ is used for the production of dies for steam-air and pneumatic hammers with a falling parts weight of over 3 tons, press dies and dies for high-speed machine stamping during hot deformation of light non-ferrous alloys, and matrix blocks for inserts of horizontal forging machines.
