Carpenter CTS-XHP Alloy (Micro-Melt® 440-XH® Alloy)
1.60 C, 0.50 Mn, 0.40 Si, 16.00 Cr, 0.35 Ni, 0.80 Mo, 0.45 V, Bal. Fe
Air hardening, high carbon, high chromium, corrosion resistant alloy which can be described as either a high hardness Type 440C stainless steel or a corrosion resistant D2 tool steel. Possesses corrosion resistance equivalent to Type 440C stainless but can attain a maximum hardness of 64 HRC, approaching that of D2 tool steel. Now available in strip product form.
This proprietary alloy is in the Carpenter CTS™ family of alloys that offer superior edge retention and surface finish, an ability to be machined to a fine edge, and consistent heat-treatability from lot to lot. Consider CTS alloys for many blade applications including commercial food processing, paper processing, textile, packaging, recycling/refuse, kitchen knives, hand tools, scissors/shears, shaving razors, sport/hunting knives, ice skates, military/defense, law enforcement, salon blades and various surgical/medical applications.
