20H23N13 wire, round, rod
Calibrated steel rod 20H23N13 (AISI 309) made according to GOST follows: 7417−75, 8559−75, 8560−78. Polished rod and silverfish — 14 according to GOST 955−77, forgings and forgings — GOST 1133−71. The composition of products 22−25% Cr, 12−15% Ni, 2% Mn, 1% Si, up to 0,3% Cu, 0,2% Ti and carbon, thousandths of a percent phosphorus and sulfur.

The circle is made by stamping — hot or cold deformation under a predetermined shape. Hot stamping — a simple and cheap method, less energy-intensive, since the effort for the hot deformation of the metal have to put much less. In the manufacture of the circle at the same time stamped several surfaces, so the circle turns smooth surface of his uniform, and the sizes observed in strict accordance with the wishes of the customer. Deviations — within the requirements of GOST. Processing of multiple surfaces is economically beneficial — possible to manufacture preforms absolutely any section due to size of the stamp. The circle can be used as forgings — interim blanks for various products.
Circle, rod and wire of heat-resistant high-alloy steel 20H23N13 (AISI 309) autensitno-ferritic class designed for the manufacture of parts operating at high temperatures 900−1000 ° C in the lightly loaded condition. These semi-finished products — limited weldability, preheating is required to 100−120 ° C with a final heat treatment. Unlike austenitic steels 20H23N13 stamp differs greater strength (almost 2 times), higher resistance to intergranular corrosion and stress corrosion cracking in chloride environments and alkalis.

This steel has a balanced characteristics of heat resistance and heat resistance, so it is popular. It contains less nickel than 20H23N18 alloy (AISI 310), which increase its resistance in environments containing sulfur. Circle, rod and wire 20H23N13 used in construction, medical, food industry, chemical, petrochemical, shipbuilding industry, aviation industry, metallurgy. Thanks to chromium and nickel, form a protective film, ability to heal itself when damaged on the surface of products. Mark 20H23N13, including circle, wire or tube 20H23N13 can replace products made from steel grades 309S, 309H, 309Cb, 309HCb, not losing them in properties. Since both the wire and rod and circle 20H23N13 have the most balanced properties of heat resistance, heat resistance, they remain among the most popular products in the metal market.
