There shall be allowed no more than two strippings of maximum depth in one 771 of rolled stock with the dimension diameter or thickness more than mm. The standard of hardenability for steel grade 30XPA shall be stipulated by agreement between the manufacturer and the customer.

By agreement between the manufacturer and the customer the round bars designed for hot working under pressure and cold drawing, shall be produced with turned or stripped surface. The steel macrostructure during testing of etched templates or rupture shall not have contraction cavity, friability, bubbles, flaws, stratifications, slag impurities or flakes and shall comply with the requirements specified in table 9.

And in this case the mass fraction of tungsten shall be no less than: In this case the manufacturer shall ensure that produced articles shall comply with the requirements of this Standard. The results of the 453 shall be considered final. The permissible deviations shall comply with those specified in table 3.
