Designation
Description
Alloy ВТ18У used: for the production of bars, rods, forgings and stampings, sheet metal; parts of gas turbine engines operating in the temperature range of +550−600 °C.
Note
Pseudo α-alloy ВТ18У different from ВТ18 lower content of aluminum and zirconium, and the additional alloying with tin. In this regard, he is somewhat smarter ВТ18. At the high-temperature properties of the alloy ВТ18У is not inferior to the alloy ВТ18 and is recommended for the same operating conditions as the alloy ВТ18.
Standards
Chemical composition
Ti is the basis.
According to OST 1 90013-81 the total content of other impurities is ≤ 0.30%. A partial replacement of molybdenum by tungsten in an amount not exceeding 0.30% is allowed. The total content of molybdenum and tungsten should not exceed the norms specified in the table for molybdenum. The total content of copper and nickel in an amount not exceeding 0.10% is allowed, including nickel not more than 0.080%. The total content of chromium and manganese in an amount not exceeding 0.15% is allowed.
