20X13 Wire, round
Circle, rod and wire of stainless 20X13 heat-resistant grades have high strength corrosion resistance, plasticity. They are produced in accordance with GOST 5632- - — — 72. As part of the 12−14% chromium, 0.6% manganese, nickel, silicon, 0.16 — 0.25% carbon, thousandths of a percent of phosphorus and sulfur. Balance is iron.
The percentage of the brand 20X13 (GOST 5632−72)
This martensitic steel grade, t ° melting its 1320−1350 ° C. Plasticity of heat resistance and allow the use of long products at t ° to 550 ° C for parts subject to vibration and shock. They also withstand short-term heating to 700 ° C. bar, wire resistant to soil and atmospheric moisture, organic acids, weak nitric acid. Wire and rods are made of round, square.

σ T — yield limit for residual deformation.d 5 — elongation at break.
Hot deformation is made at t ° from 1100 to 900 ° C with air cooling. At t ° 750 — 800 ° C softening annealing is performed with an exposure in an oven at 500 ° C. Is required for hardening heating to 950 — 1000 ° C with cooling in oil. Welding is performed by the electric arc and argon-arc manual or automatic method. If the bar is thicker than 10 mm, pre-heating is desirable to 250−400 ° C and a final heat treatment for stress relief.
Circle, wire rod and steel 20X13 used in power engineering for crackers parts, steam generators and pumps. They are widely used chemical, petroleum, shipbuilding, food processing, medical industry, as well as the recently — building to create a decorative architectural elements.
