This information is provided only as a
general guide to the builder. The mechanical properties
listed are for ideal conditions of uniform tension. Individual
judgement is required in cases where uneven or sudden
loading, bending, or shearing forces, or high corrosion
potentials are present.

Definitions
Tensile Strength: The
maximum load in pounds per square inch that a sample
will carry before breaking under a gradually applied
load.
Yield Strength: The stress
that causes a specified permanent increase in length
of a tensile test sample.
Elongation: A measure of
ductility. Expressed in percentage of the original length
and the extended length that takes place in a tensile
test.
Intergranular Corrosion: Corrosion
that occurs at the grain boundaries in austenitic stainless
steels that have been heated between 850° and 1450°
F.
Stress Corrosion Cracking: Catastrophic
failure by intragranular cracking occurring in austenitic
stainless steels and other metals. It is caused by the
combined action of a corrosive environment and stress.
This often occurs without any outward appearance of
general corrosion attack.
