resistance of the material, the other properties being little affected. The effect
is known as weld decay and results from the precipitation of chromium-rich
carbides at grain boundaries. This removal of chromium from grains to the
boundaries decreases the corrosion resistance. One way of overcoming this is
to stabilize the steel by adding other elements such as niobium and titanium.
These have a greater affinity for the carbon than the chromium and so form
carbides in preference to the chromium.
