Circle, bar, wire 20H23N13 - 1.4833 - aisi 309
A calibrated rod of steel 20Х23Н13 (AISI 309) is performed according to the following GOST: 7417−75, 8559−75, 8560−78. Ground rod and silver — according to GOST 14 955−77, forgings and forged billets GOST 1133−71. In products 22−25% Cr, 12−15% Ni, 2% Mn, 1% Si, 0.3% Cu, 0.2% of Ti and carbon thousandths of a percent of phosphorus and sulfur.
Percentage composition of the brand 20Х23Н13 (GOST 5632−72)
The circle is made by stamping — hot or cold deformation under a predetermined shape. Hot stamping — a simple and cheap method that is less energy-intensive, because of effort to the deformation of the hot metal you need to make much less. In the manufacture of the punched circle at the same time, several surfaces, so a circle turns smooth, its surface is uniform and sizes are observed in exact accordance with the customer’s wishes. Deviations within the requirements of GOST. Processing of several surfaces economically viable — is possible manufacturing any section due to the set size of the stamp. A circle can be used as a forging — intermediate preform for different products.
Round, rod and wire made of heat-resistant high-alloy steel 20Х23Н13 (AISI 309) autosite-ferritic class is designed for manufacture of parts operating at high temperatures 900−1000°C. lightly condition. Such semi — limited welding, a necessary preliminary heating to 100−120°C with the final heat treatment. In contrast to austenitic steels, grade 20Х23Н13 is more strength (almost 2 times), more resistant 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 alloy 20H23N18 (AISI 310) that increase its resistance to environments containing sulfur. Round, rod and wire 20Х23Н13 used in construction, medical, food industry, chemical, petrochemical, shipbuilding industry, aviation, metallurgy. Thanks to chromium and Nickel, on the surface of products forms a protective film that is able to repair itself when damaged. Brand 20Х23Н13, including the circle, wire or pipe 20Х23Н13 can replace products made of steel grades 309S, 309H, 309Cb, 309HCb, not losing them. Because both the wire and rod, and the circle 20Х23Н13 have the most balanced properties of heat resistance, heat resistance, they remain one of the most popular products in the metal market.
