20H23N13 (AISI 309) — heat-resistant high-alloy steel autensitno-ferritic class, intended for the manufacture of parts operating at high temperatures 900−1000 ° C in the lightly loaded condition. Ferritic steel attributed to the heat resistance. They withstand t ° to 600 ° C. At higher temperatures, use austenitic steel. 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 — limited weldability, preheating is required to 100−120 ° C with a final heat treatment.
Stainless steel pipe from this nickel-chromium alloy in accordance with GOST 5632−72 contains in its composition 22−25% Cr, 12−15% Ni, 2% Mn, 1% Si, up to 0,3% Cu, 0,2% Ti and carbon, thousandths of a percent of phosphorus and sulfur. Requirements for fire resistance complicate the composition of the steel and increases the number of additional additives,
The percentage of 20H23N13 grade (GOST 5632−72)
The pipe can be made seamless way — Extruded or welding — electric welding. Depending on the type of surface of the pipe may be indicated in the catalog as matt, sanded or mirrored, ie polished… Long products, incl shaped made by the following guests: 2879−69, 2590−71, 2591−71, 5949−75.

This steel has a balanced characteristics of heat resistance and heat resistance, so it is popular. This tube can replace pipe 20H23N14S2 brand if working conditions neotyagoschёnnye. It contains less nickel than 20H23N18 pipe steel (AISI 310), which increases its resistance in environments containing sulfur. 20H23N13 pipe used in construction, medical and food industry, in the chemical, petrochemical, shipbuilding industry, aviation industry, metallurgy. These pipes are resistant to aggressive environments, due to chromium and nickel, on the surface of the protective film is formed, capable of self-healing. Such pipes for a long time do not need to be replaced, minimize maintenance, do not require painting.
All submitted articles 20H23N13 grade (AISI 309) certified. The technical documentation includes data on the chemical composition, limiting the percentage of impurities; mechanical properties of products. We can buy in bulk, any semi-finished products for large-scale productions. We also offer optimal conditions for retail customers. High level of service and efficiency of service are the face of our company.
