Compared with 5-Bar Treadplate in Alloy 5754-H111

Alloy 5754 has slightly higher corrosion resistance and better weldability than alloy 5052.  The two alloys have similar physical and mechanical properties and fabrication performance.

 

Tensile Strength and Shear Strength are very similar whilst Proof Strength of 5754 is only 100 as against 175 for TripleGrip.
