100 ksi-160 ksi Yield

Impact 100-160 KSI High Strength Plate

CMC Impact Metals high strength steel plate provides greater strength compared to standard steel plate. Offered in KSI range from 100 – 160, it can be welded, is formable and ready to be CNC cut-to-fit. Meets chemical and specific mechanical properties and specifications in the U.S. and Canada. Primarily for use in long-haul truck frames, heavy brackets, construction cranes and rail cars. Also for use in structural designs where higher strength-to-weight is required.

Steel plate, heat-treated to various strength levels while retaining good toughness. Product is intended for use in applications requiring a combination of high strength, weldability, and toughness.

Recommended Welding Practices

This steel can be welded by conventional processes such as SMAW, SAW and GMAW provided that the weld procedures used are suitable for this grade and the intended service of the steel. Proper weld procedures should include the following:

  1. Low Hydrogen conditions must be used.
  2. Preheating to 200-500ºF (93 – 260°C) is required for heavy sections, (>0.750"), and recommended for thinner sections to eliminate moisture.
  3. Slow cooling rates should be avoided to prevent low toughness in the HAZ.

*These statements are general guidelines. CMC Impact Metals is not responsible for the results of any welding work performed.
