The different solution heat treatment and annealing treatment received by the steel material are presented in details. The steel shall conform to the specified chemical composition and room temperature mechanical requirements. The forgings shall be produced with prolongations for testing, unless otherwise specified. The number of and procedure for tension test for forgings depending on their weight are presented. The tension test specimens shall be taken from the test prolongations or from the forgings.
