Breaking Strength of High-Tensile Wire

Often confused, PSI and KSI are really just a conversion of one another. In terms of advertising our wire PSI and KSI represent minimums relative to breaking strength.

PSI=Pound per square inch

KSI=Kilo-pound per square inch=1000 PSI

210 KSI=210,000 PSI

PSI  used to calculate the breaking strength of wire

Area=(½ x diameter)² x Π

Where minimum breaking strength is =Area x PSI

Example: 12½ gauge, 210,000 PSI wire

Area= (½ x .099″)² x 3.14=0.0077″²

Min. breaking strength=0.0077″² x 210,000 PSI= 1617 pounds

  *This particular wire can withstand a force of up to 1600 pounds, before breaking.

    Can you reverse engineer your formula for converting breaking strength to tensile, instead?

      PSI=Breaking Strength/Area

      1617 pounds/.0077”2=210,000 PSI
