Abstract:

Research results are provided for creation of high-strength economically alloyed corrosion-resistant steel 14Kh17N2AF for submersible centrifugal electric pump shafts. Tests are conducted for steel mechanical properties and corrosion resistance. The fine structure and composition of carbide and carbonitride phases are studied and grain structure and precipitating phase distribution are evaluated. The new steel 14Kh17N2AF is not inferior to the mechanical properties of steel 03Kh14N7B used normally for these purposes, and it has an advantage with respect to corrosion resistance indices, machining, and economy. Results of full-scale testing of electric pump shafts in boreholes establish that shaft service life increases by 30\%, and pitting corrosion resistance improves by 20\%.
