Abstract (en)
[origin: WO2018210575A1] The invention relates to a safety steel or wear-resistant steel (1) composed of a multi-layer steel material composite, comprising a first layer (1.1) composed of a steel which in the hardened or annealed state has a hardness of > 350 HBW, and at least one second layer (1.2) which is cohesively connected to the first layer (1.1) and which is composed of a softer steel in relation to the first layer (1.1), wherein the second layer (1.2) has a lower hardness, by at least 20%, than the first layer (1.1) in the hardened or annealed state. The invention also relates to a corresponding use of the safety steel or wear-resistant steel (1).
