Steel types overview

1.2003 / 1075+Cr / 75Cr1

Low-alloy tool steel with very good machinability and polishability. Universally usable for non-stainless knife blades. Also suitable for forging.

1.2235 / L2 / 80CrV2

All-purpose carbon steel with very good machinability and polishability. Optimally suited for non-stainless knife blades. Also suitable for forging. This steel is optimally suited for blades that are exposed to shock stresses.

1.2379 / D2 / X155CrVMo12-1

Ledeburitic high-performance cutting steel. Moderate machinability, good dimensional stability and toughness. Extremely wear-resistant and low distortion. Good tempering resistance. Good hardening.

1.2510 / O2 / 100MnCrW4

All-purpose carbon steel with very good machinability and polishability. Optimally suited for non-stainless knife blades. Also suitable for forging.
