Standards
Chemical composition
Fe is the basis.
According to TU 14-1-2816-79, the chemical composition is given for steel grade 015Х18Н15Р30-ВД (ЭП168Б-ВД). In the finished metal, the aluminum content is not more than 0.30%, nitrogen is not more than 0.050%. In the finished metal, the content of cobalt is controlled, the results of the control are not a defective feature, but are indicated in the certificate. By agreement of the parties, the pipe billet is supplied with a cobalt content of not more than 0.0050%. In the finished metal, if the requirements of TU are complied with, the deviation by the content of carbon + 0.0050%, the boron content ± 0.040% is permissible. By agreement of the parties, boron content is allowed up to 0.40%.
