What Does "KSI" Mean in Steel? | Reference.com

KSI is an abbreviation for kilopounds per square inch, or 1,000 pounds per square inch. It is a measure of the tensile strength of steel. Tensile strength is the amount of stress a material can undergo before breaking. It refers specifically to stress induced by pulling or stretching; compression stress is measured with a different value.
