Abstract
The present invention relates to an austenitic heat-resistant high-temperature steel for the production of articles used in combustion products from highly-aggressive organic fuels (e.g. high-sulphur black oils, carbons, shale, crude-oil cracking products and others) at temperatures of up to 650°C, mainly pipes for the heating surfaces of steam superheaters. The use of the chromium-manganese steel increases the steel service characteristics (high-temperature strength increased more than twice at working temperatures and mainly upon repeated starting and stopping and length plasticity of 35 to 40 %), the exploitation reliability and the functional resources at least two or three times. To this end the austenitic heat-resistant high-temperature steel includes carbon, chromium, manganese, silicon, nickel, copper, zirconium, cerium, titanium, niobium and iron as well as aluminium and boron. The components are selected according to the following proportions: from 0.05 to 0.15 wt. % of carbon; from 1.0 to 2.0 wt. % of silicon; from 8.0 to 16.0 wt. % of manganese; from 8.0 to 15.0 wt. % of chromium; from 0.5 to 3.8 wt. % of nickel; from 0.5 to 6.0 wt. % of copper; from 0.01 to 0.09 wt. % of zirconium; from 0.01 to 0.15 wt. % of cerium; from 0.04 to 0.1 wt. % of titanium; from 0.2 to 3.0 wt. % of niobium; from 0.01 to 0.25 wt. % of aluminium; from 0.001 to 0.08 wt. % of boron; the balance consisting of iron and unavoidable impurities.
