Technological properties

Name The value
Features of production Casting on the other 1-92-98-85 supplied in the hardened and artificially aged condition in the T5 mode in accordance with OST 1 90088-80. For castings manufactured by the method for forming liquid metal, related to the groups control 2 and 2A allowed the testing of mechanical properties directly on the samples cut from the body of a casting from the party. All other requirements for castings according to the technical requirements, acceptance rules, test methods, labelling and packaging must comply with the requirements OCT 1 90021-79.
