Sheet, strip KHN70JU - ЭИ652

Sheet, strip KHN70JU - ЭИ652

Production

Sheet, strip and foil stamps KHN70JU are the products of long products. They are made of heat-resistant alloy. The composition of finished products fully complies with GOST 5632−72 and specifications 12766.4−77. The composition of the alloy contains Nickel 65,073 — 71,2%, chromium 26 to 29%, iron 1%. As additives added to the batch aluminum — 2.8 to 3.5%, manganese 0.3%, phosphorus up to 0,015%, silicon — 1% carbon, barium — less than 0.1% and sulfur — about 0.012%.

KHN70JU sheet produced according to GOST 24982−81, which regulates the quality of hot-rolled and cold-rolled of heat resisting alloys on iron-Nickel and Nickel-based. Standard high-temperature rolled sheet has a thickness more than 1 mm and sorted by type of edge, flatness, precision rolling. Flatness is a special, superior, normal and high. Accuracy — high and normal. Edge — edged and not edged.

Heat treatment and welding

Recommended temperature of quenching of the alloy in air or in water not higher than 1200 °C. the Temperature of raskopki began at the beginning of 1150 — 1180 °C, and at the end of — 850 °C. the Rod is quenched at a temperature of 1050−1150°C in air. This alloy is easily weldable any type. For manual electric arc welding used electrodes OzL-35, OzL-25.

Use

Sheet, strip and foil KHN70JU are widely used in various fields: in heavy engineering, construction, medical and chemical industry, in the production of Cutlery and tableware. They are especially in demand in those areas where materials with high resistance to thermal overload, for example, in the construction of turbines, motors, combustion chambers, heating units, various furnaces. Heat resistant steel sheet KHN70JU produce designs and components for space and missile defense. The high content of Nickel, chromium in the alloy enables the products to withstand high temperature (1000°C) and not lose their high resistance to corrosive and acidic environments.
