Heat-Treated Stainless Steel Blades
Suitable for industrial and medical applications, 400 series martensitic steel is much more corrosion-resistant than carbon steel and can be sharpened to equally-keen edge sharpness. Cadence maintains an extensive inventory of Razor Blade Stainless steel in thicknesses from .010”-.062” thick, as well as 420 “Cutlery Grade” Stainless steel.
