Weller 166-HT

Weller 166-HT is a fine grained alloy shafting designed to resist high torque and torsional stresses. The balanced chemistry including chromium, manganese and molybdenum coupled with a continuous heat-treating process assures excellent surface and core properties. The optimum core properties and the high tensile strength of Weller 166-HT enhances the performance of this maintenance tested hot rolled steel.
