Prehardened Steel

Far too often applications require more than a surface hardness. For over 30 years Pennsylvania Steel has been providing prehardened FLEXOR® blanks requiring a variety of mechanical properties. Pennsylvania Steel can provide a rough machined and heat treated certified blank guaranteed to reach maximum mechanical properties for each specific part. The letter designation following FLEXOR® is our way of coding for a prescribed target of mechanical properties without settling for just a surface hardness. For post-machining hardening just ask for FLEXOR®.

It is often necessary to provide a decarb free surface or rough silhouette prior to hardening to facilitate maximimum properties. Allow our experts to assist in providing the optimal prehardened blank to meet your needs.

Note: Mechanical properties are representative of samples while actual results may vary depending upon section size, heat treatment, stock size, reduction, etc.

Special hardness range available upon request.
