Circle, bars and wire stainless and heat resistant 20X13 brand have high strength resistance to corrosion ductility. Produced according to GOST 5632 — - — - 72. In the composition 12−14 percent chromium, 0.6% manganese, Nickel and silicon 0,16 — 0,25% of carbon, thousandths of a percent of phosphorus and sulfur. The balance is iron.
Percentage composition of the brand 20X13 (GOST 5632−72)
This steel martensitic class, t° melting her 1320−1350°C. the Plasticity and heat resistance allow the use of rolled steel at t° 550 °C for parts subject to vibration and shock loads. They can also withstand short-time heating to 700 °C. the rod, wire resistant to soil and atmospheric moisture, organic acid, weak nitric acid solutions. Wire and rods are manufactured in round, square section.

σIn the limit of short-term strength;
σT is the yield stress for permanent deformation.d5 — elongation at break.
Hot deformation performed at a temperature from 1100 to 900 °C with air cooling. At a temperature of 750 — 800 °C annealing softening is carried out by aging in a furnace at 500 °C. For hardening is required heat to 950 — 1000 °C with cooling in oil. Welding is carried out with electric arc and argon-arc manual or automatic method. If the thickness of the rod of more than 10 mm, the desired preheating to 250−400°C and a final heat treatment to relieve residual stresses.
Round, rod and wire of steel 20X13 used in power engineering, for details cracking plants, steam generators and pumps. They are widely used in chemical, oil industry, shipbuilding, food, medical industry and recently the construction to create decorative architectural elements.
