Nominal Analysis
0.33 C, 0.40 Mn, 0.50 Si, 13.50 Cr, Bal. Fe

Has been used for long-run molding jobs and provided good protection against corrosive hazards due to machine shutdowns and storage between runs, plastic compounds, and humid climates.

This alloy is in the Carpenter CTS™ family of alloys, offering 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.
