20Х23Н13 sheet is hot rolled. Hot-rolled thick plate (4−160 mm) is made according to GOST 19903−74; 1577−93. Thin sheets (0.5 to 3.9 mm) produced hot-rolled method in accordance with the GOST 16523−89 and 19903−74. Thin hot-rolled sheet is heat-treated method, and its surface is netravlenoy and etched. Steel sheets 20Х23Н13 can be supplied galvanized, width 710−1800 mm and thickness 0.5 — 2.5 mm.
When welding requires preheating the sheet to a temperature of 100−120°C, final heat treatment seams.
Tape, sheet used in the manufacture of various tanks, operating at high pressure at the facilities of petrochemical oil, gas industry, power engineering, for production of components of steam generators, pumps, etc. This steel is widely used in petroleum, chemical industry, medical and food industries, shipbuilding, pulp and paper industry.
