20Х20Н14С2
It is a heat-resistant high-alloy chromium-nickel steel of austenitic-ferritic class. It is used for manufacturing of such rolled metal products as rounds, rods, wires. It contains 19-22% Cr, 12-15% Ni. As an additive to the charge 2-3% silicon, up to 1.5% manganese, 0.3% copper, 0.2% each titanium and carbon, thousandths of a percent phosphorus and sulfur are used.

Production
Calibrated steel rod grade 20Х20Н14С2 produced according to the following GOST: 7417-75, 8559-75, 8560-78, Grinded rod and silver - GOST: 14 955-77. Forgings and forged blanks - GOST: 1133-71, 25 054-81. Forging temperature - 1170 ° C at the beginning of the process and 850 ° C at the end. The cross-section of long products can be round, hexagonal, square. Curvature is measured on products over 1 meter in length, with a measure taken at least 15 centimeters from the ends of the product. The maximum length deviation should not be more than 3 centimetres at length up to 4 metres, 5 centimetres at length up to 6 metres and 7 centimetres at length over 6 metres. The quality of the steel allows the production of products from 1 to 6 meters, The lower the carbon content of the alloy and the lower the quality of the steel itself, the greater the minimum length of the dispensed product.

d5 - relative elongation at break.Application
From such circles, rods, wires are made of parts of thermal furnaces, furnace conveyors designed for operation up to 1000 °C, boxes for carburizing and other parts of high-temperature industrial furnaces. In metallurgy, cementation boxes are used to surface saturate low carbon steel with carbon by diffusion to increase its hardness and wear resistance. Typically, carburizing is applied to alloys with a carbon content up to 0.2% and alloy steels. Inside the carburizing structures, temperatures of 850 - 900 °C are reached.
