Knife Steels (Slitting / Shearing / Food Processing / Hunting)

Our knife steels can be used for slitting, shearing, food processing, and hunting.

No other applications put a material’s properties to the test in a more dramatic way than those of cutting and shearing. Alongside wear resistance and edge-holding ability, the freedom from distortion and flatness—even when influenced by elevated temperatures—are decisive markers of quality.

BÖHLER & UDDEHOLM are market leaders in manufacturing high performance steels for industrial knives, and as such can offer tried-and-tested, highly wear-resistant steels for all applications, e.g. for the woodworking, metal working, plastics processing, or paper industries and recycling industries. They also supply steels for food processing knives; predominantly powder metallurgy and conventional stainless steels which offer excellent wear, toughness, and corrosion-resistant properties.
