03Х13Н8Д2ТМ, ЭП699 tape, sheet, round, wire


Corrosion resistant austenitic aging of the alloy 03Х13Н8Д2ТМ (ЭП699) is used for the manufacture of welded structures, operating at a temperature from 20 °C to -196°C. the most important qualities of this material include high corrosion resistance, hardness up to 9000 N/mm, good processability, availability of all types of processing. Due to the optimum composition of alloying elements: chromium, Nickel, molybdenum, copper, titanium, etc., this alloy resists the effects of moisture and aggressive factors, providing reliability and durability of the equipment. Steel is not prone to stress corrosion cracking in conditions of high humidity, salt fog, industrial atmosphere rich in sulphur.

Steel is smelted in open induction furnaces. Manufacture of semi-finished products normalized following: 14−1-2176−77; 14−1-1655−75. The semi-deformed in hot state (in the temperature interval 1160−850°C) and in cold condition. Hardening of semi-finished products is at a temperature of 880 °C with air cooling. Aging at a temperature of 600 °C for 2 hours.
