CTS B75P is a powdered steel produced by Carpenter Steel of Reading, Pennsylvania U.S.A.

Carpenter’s CTS B75P is comparable in elemental composition to BG42 blade steel but is produced using a powdered steel manufacturing process rather cast steel construction. Powdered steel manufacturing renders the ingredients and carbides making up the steel’s structure, more consistent in grain size to each other and homogenize the steel. For the knife user this translates into a high-performance knife steel with exceptional wear and corrosion resistance and long term edge retention. CTS B75P’s hard vanadium carbides further augment its wear resistance and edge retention making it the new knife steel that production knife companies and custom knifemakers are excited to use.
