Alloy BT23]
Designation
Description
Alloy BT23] is used: for the manufacture of kavitatsionnogo products.
Note
High strength alloy widely used. The developed technology of manufacture of stampings and forgings weighing up to 3.5 tons with the strength of over 1100 MPa, processes, WTO and textural hardening for production of ball-cylinders of σin>1300 MPa and pipes of variable section.
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%. In flat rolled products of alloy VT23 up to 10 mm thick, the aluminum content should be 4.00-5.50%, and in the other types of semi-finished products - 5.20-6.30%.
