HN70YU sheet, strip, foil
HN70YU sheet, strip, foil — products of alloy high-temperature heat-resistant steel having high corrosion resistance. Doping can improve its physical and chemical properties. The basis of an alloy of nickel, the minimum content of which should not be lower than 65.073%, and the maximum — higher than 71.2%. Second place in terms of covers chrome — 26−29% of the total weight. Unlike similar alloys in this steel grade iron is added as an additive, the amount does not exceed 1%. It refers to a low-carbon alloy, as it contains up to 0.1% C. The additives are used as silicon and manganese — 0.8% and 0.3% respectively. The structure also includes sulfur (up to 0.012%), phosphorus (up to 0.015%), selenium (up to 0.03%), aluminum (2.8 — 3.5%), copper (up to 0.07%) and barium (less than 0.1%). This is easily weldable material, is available to all types of welding work without restrictions.

Products brand HN70YU manufactured according to GOST 5632−72 (for the brands high-alloy steels, high-temperature corrosion-resistant heat-resistant alloys) and GOST 12 766.4−77 (technical conditions of hire). Also on the products of this steel is subject to certain specifications. For example, the production of the tape 24 normalizes GOST 982−81, and cold-rolled sheet — TU and TU 14−1-493−72 14−1-810−73. The hot rolling is subjected to forging in the range of t ° 1150 ° C — 900 ° C. Sheet and strip after manufacture are heat treatment. Tempering tape made in air at a temperature of 1100−1130 ° C, quenched and cold rolled sheet at 1100−1150 ° C under a water spray, water or air.

For details of the combustion chambers, screens, diffusers, pockets afterburners (creating a temporary additional thrust chambers in jet engines). Such products are capable of operating at low voltages and high temperatures 1100−1200 ° C, above which already begins active dross. Sheet, ribbon used in the production of heating elements, parts welded components in power engineering. fixing elements of this steel can withstand very high temperatures. Widely used in machine building, metallurgy, construction industry. A thin sheet, foil used to create refractory corrosion coatings.
