Through-thickness Properties
Although not easily detectable to the eye, rolled steel does not have a homogeneous structure.
This is because the process of rolling squeezes the alloy grains in the microstructure such
that they overlap by becoming long and thin in the direction of rolling. In most applications the
principal stresses and strains imposed on a steel product will be in this benefi cial lengthwise
direction. Occasionally, however, loads will be imposed in the transverse “through-thickness” or
“Z” direction. Then the ability of the grains to adhere to each other is crucial.
The situation when the through-thickness properties of the steel are most likely to be important
is in heavily-welded “cruciform” type joints. This is because when welds shrink on cooling
the locally imposed strains can reach yield and the parent material must be ductile enough to
redistribute these strains. This requires the steel to have an appropriate “Z-quality”.
