Circle rod 20H23N18
Stainless steel bar, rod of steel 20H23N18 (AISI 310s) are made of hard alloy alloy austenitic, It is the major alloying element in accordance with GOST 5632−72 is chromium is contained in an amount of 22−25%. The more its share in the composition, the higher the corrosion resistance. If chromium more than 17%, the steel becomes resistant to aggressive oxidizing environments. 12−15% Ni in the composition give the necessary plasticity and improve corrosion resistance and heat resistance. In addition, the alloy doped with 2% manganese, 1% silicon, 0.2% carbon, thousandths of a percent of phosphorus and sulfur.
Percentage composition of the brand 20KH20N14S2 (GOST 5632−72)
Calibrated 20KH23N18 steel rod made according to the following GOST: 7417−75, 8559−75, 8560−78. Ground rod and silver — GOST: 14 955−77. Forgings and forged billets 20H23N18 — GOST: 1133−71. For the production of rod 20KH23N18 use the methods of hot and cold rolling. The temperature of the wrought rod — 1170 °C at the beginning of the process and 850 °C at the end. The cross section of the rod has the shape of a circle. In some cases, allowable deviation of ovality is the difference between the largest and smallest diameters in the same cross section should not be more than 50%.

σIn the limit of short-term strength;
σT is the yield stress for permanent deformation;d5 — elongation at break.
- Accurate — typical, high and elevated, in accordance with it, the product gets marked B, A, or V;
- The form — rolled with a diameter up to 9 mm, comes in the form of coils, with a larger diameter — in the form of bars;
- Length — off-gage, dimensional and multiple dimensional. Bars and rods of high alloy steel comes with a length of 1−6 m;
Forgings, details of combustion chambers, bandages, clamps, suspension parts, fixing boilers, muffles, for operation at t° 1100 °C. a Steel ring can be used for the production of springs, washers, etc. technological goods. In construction as a reinforcing element, for the manufacture of staircases, balconies, grounding systems and lightning protection. From this circle made fasteners in the construction of highways, bridges, tunnels. This product well prevents aggressive influence of the external environment and actively used in the marine industry.
