Increasing the corrosion and erosion resistance of centrifugal ptnnp inapellers for the petroleum and gas extraction industry

Abstract

In the text describing the casting properties of some new steels, on page 386, line 43, the liquidus temperature (~C) for steel 10Khl8N9TL should be 1440 instead of 1140.In Fig. 2, on page 388, the caption should read -Impeller of 06Khl3N4MBL steel after pr~tuction tests in highly minerafized chloride water with abrasive particles (absence of hydrogen sulfide).
