Superior strength and surface quality

CMC offers TruSTRENGTH high strength steel plate in a variety of grades ranging from 110 to 140 ksi.

Melted and manufactured in the USA, our high-strength plate meets ASTM chemical and mechanical properties and can be welded, is formable and ready to be fabricated. 



Our TruFLAT Guarantee ensures that TruSTRENGTH plate excels in downstream fabrication processes. Our state-of-the-art heat treating, quenching and tempering process reduces and relieves the stresses induced during manufacturing, ensuring the parts remain flat when cut.
