Environmentally Assisted 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.
Sulfide stress cracking of nickel-containing low-alloy steels
Low alloy steels with a nickel content greater than 1% are not allowed in sour service applications. This paper reviews the effect of nickel on the hydrogen embrittlement performance of low alloy steels.
Effect of nickel on the phase transformation kinetics of low alloy steels
This posts summarizes the main effects of nickel on the phase transformation of kinetics of low alloy steels.
Hydrogen Embrittlement of Nickel Alloy Steels
This post illustrates a possible sulfide stress cracking mechanisms at the open circuit potential for low alloy steels.
Hydrogen diffusion control during stress corrosion cracking of magnesium alloy AZ31B in chloride solutions – Abstract
SCC of AZ31B alloy was studied in NaCl solutions at different potentials and chloride concentrations using the slow strain rate technique. A combination of pre-exposure tests followed by immediate straining or straining after a dry air exposure delay helped to weight the relative importance of anodic damage accumulation versus increased hydrogen charging during open-circuit potential pre-exposure. The dependence of ductility with pre-exposure time and the fracture surface of embrittled samples suggest that hydrogen embrittlement of AZ31B was controlled by hydrogen diffusion.
