This is the first of a series of articles on the effect of nickel on the hydrogen embrittlement resistance of low alloy steels. In this paper, we investigated how nickel in solid solution in the ferrite phase affected hydrogen permeation.
The history of NACE MR-0175, ISO 15156, and the 1% nickel limit – Timeline
This blog entry presents the development of the NACE MR-0175 in a historical perspective alongside research advancements in physical metallurgy and sulfide stress cracking.
ISO 15156-3 will set new restrictions on UNS S174000 (17-4PH)
This article describes the results of a recent NACE MR0175/ ISO 15156 ballot that imposes stringent maximum allowable stress values.
