Steel Carpenter CTS® XHP Alloy

CTS XHP can be used for special knives, where fine carbide and alloy distribution is possible, used to produce very sharp edges. The material can be easily ground into the thin profiles required for cutting tools. CTS XHP blades can be finely polished to a high shine or have a uniform matte finish.

Steel Carpenter CTS<sup>®</sup> XHP Alloy

CTS XHP is an air-hardening knife steel with a high carbon and chromium content (alloying elements: 1.6% C, 0.5% Mn, 0.4% Si, 16% Cr, 0.35% Ni, 0.8% Mo and 0.45% V). It is corrosion-resistant and at the same time has high hardness after refinement (up to 64 HRC!). It can be labeled as 440C steel, yet with enhanced corrosion resistance and as a better tool steel (compared to D2) in the field of wear resistance.

It is available in the form of rolled strips from Carpenter dealers. As a patented alloy (Carpenter CTS™ trademark), it offers great possibilities in terms of machinability in the supplied condition, but for the production of a fine edge through grinding after refining. The obtained edge is extremely wear-resistant and thus its use is directed towards the production of blades for the food industry, packaging technology, medical applications, sports (skates), military, police, hunting (knives), and even household use (razors, scissors).

In comparison with CTS 204P steel (also a product of Carpenter CTS™), it can be considered as a cheaper and classic steel. It does not achieve the qualities of the mentioned powder steel, but its properties are above standard, just below the threshold of powder steels, which can be deduced from the alloy contents of both steels.

For optimal corrosion resistance, the surface must be free of burrs and foreign particles, which should ensure that the finished parts are treated accordingly.
