Is useful model it is intended [dl] of [izgotovleni] of the components, which prolongedly work with the intensive dynamic loads before the corrosion-active aqueous medium with the presence of dissolved hydrogen sulfide, the ions of chlorine, salts of alkaline earth metals, petroleum products, for example the components of immersion [oborudovani] with oil production. Bars, including with the machined surface, are made from the stainless steel with the yield point with the time of ripening of [zhenii] of in the range 110-150 [kGs]/[mm]2, to the value of impact before [zkosti] not less than 7, 0 kG·[m]/[sm]2 and by the equivalent of [soprotivleni] of the pitting corrosion of >15.
