Abstract

The threshold stresses and character of hydrosulfide corrosion cracking of high-alloy nickel alloys and steel 12Kh18N10T in an aqueous solution of 5% NaCl plus 0. 5% CH//3COOH, saturated with hydrogen sulfide under normal conditions, were determined the restriction of the hydrogen embrittlement of alloys to thin surface layers is demonstrated fractographically. The high corrosion resistance under these conditions and at an increased partial pressure of hydrogen sulfide (1. 5 MPa) makes it possible to recommend molybdenum-containing alloys (40NKKhTYuMD, 06KhN28MDT, and 36NKhTYuM5) for service in media of deposits of natural gas with a hydrogen sulfide content to 25% by volume (Astrakhan type of gas condensate deposit).
