Production

Calibrated rod of steel 20X23H13 (AISI 309) is produced according to the following GOST: 7417-75, 8559-75, 8560-78. Grinded rod and silver - according to GOST 14 955-77, forgings and forged blanks - according to GOST 1133-71. Products consist of 22-25% Cr, 12-15%Ni, up to 2% Mn, 1% Si, up to 0.3% Cu, 0.2% Ti and carbon, thousandths of a percent phosphorus and sulfur.

Circle is made by punching - hot or cold deformation to a given shape. Hot stamping is a simpler and cheaper method, less energy-consuming, as less effort needs to be applied to deform the hot metal. In the manufacture of a circle, several surfaces are stamped at once, so the circle is smooth, its surface is homogeneous, and the dimensions are observed in exact accordance with the wishes of the customer. Deviations are within the GOST requirements. Machining of several surfaces is economically advantageous - it is possible to produce blanks of absolutely any cross-section due to the specified die size. Circle can be used as forging - intermediate billet for various products.

Quality

Circle, bar and wire of heat-resistant high-alloy steel 20X23H13 (AISI 309) of austenitic-ferritic class are designed for the manufacture of parts operating at high temperatures of 900-1000 ° C in low-loaded state. Such semi-finished products - limited weldable, requires preheating to 100-120 ° C with a final heat treatment. Unlike austenitic steels, grade 20Х23Н13 is characterized by higher strength (almost 2 times), greater resistance to intergranular corrosion and corrosion cracking in chloride media and alkalis.

Using

This steel has balanced characteristics of heat resistance and heat resistance, which is why it is so popular. It contains less nickel than the alloy 20X23H18 (AISI 310), which increases its resistance in environments containing sulfur. Circle, bar and wire 20X23H13 used in construction, medicine, food industry, chemical, petrochemical, shipbuilding industry, aircraft and metallurgy. Thanks to the chromium and nickel, on the surface of the products is formed a protective film capable of self-repair in case of damage. The brand 20X23H13, including circles, wire and tube 20X23H13, can replace products made of steel grades 309S, 309H, 309Cb, 309HCb, not yielding to them in properties. Since both wire, rod and circle 20Cr23Ni13 have the most balanced properties of heat resistance, heat resistance, they remain one of the most popular products in the market of rolled metal products.
