Specimens of 1Cr18Ni9Ti stainless steel were prepared by low temperature elongation deformation at-70℃ to obtain various martensite contents.The phase transition process was examined by TEM,XRD and metallography.Pitting susceptibility of the steel in 1 mol/L NaCl was evaluated by electrochmical hysteresis technique and polarization resistance measurements. Both α’-and ε-martensite were observed after the elongation deformation.The content of α’-martensite increased with increasing degree of deformation,while the amount of ε-martensite was consistently low and remained unchanged.These ferromagnetic phases had significant effect on the pitting susceptibility of the steel.When their content was less than 4.58% or more than 25.5%,the pitting susceptibility increased with the increasing amount of ferromagnetic phases.In the range from 4.58% to 25.5%,however,the specimens containing more martensite were found to be less susceptible to pitting.These findings were briefly explained.

The effects of hydrogen on the pitting susceptibility were investigated by carrying out the ASTM-G48 standard ferric chloride tests. The variations of pit density, pit size distribution, average pit diameter and apparent pit area percentage with hydrogen charging current density and immersion time were statistically examined.

Type 310 stainless steel foils were precharged with hydrogen at different current densities. The effects of hydrogen on the pitting susceptibility were investigated by carrying out the ASTM-G48 standard ferric chloride tests. The variations of pit density, pit size distribution, average pit diameter and apparent pit area percentage with hydrogen charging current density and immersion time were statistically examined. Hydrogen in 310 stainless steel greatly promoted the pitting initiation and the pit growth. Average pit diameter D increased linearly with logarithm of immersion time t, i.e., D=αlnt+β. The value of constant a increased with the rise of charging current density. The hydrogen interactions with defects both in surface film and metal substrate were used to explain its deleterious effects on the resistance of pitting corrosion. It was considered that hydrogen accelerated pitting corrosion mainly by formation of positive charge regions around defects in the surface film.

用ASTM-G48标准研究了氢对310不锈钢点蚀的影响。对于不充氢的样品,经过6天的时间也不发生点蚀,而对于预充氢的样品,几分钟后就有大量点蚀。点蚀的密度和大小均随着氢含量的增加而增加。点蚀坑的直径D与浸泡时间t的对数呈直线关系:D=αlnt+β。α值随氢含量增加而增大。
