Abstract
Official abstract text for this publication.
Methods for hardening a metal sheet material include applying at least one peening stream to the metal sheet material, wherein at least one peening stream is applied, in each case, to a front side of the metal sheet material and a rear side of the metal sheet material, respectively, at least at times simultaneously. In one example, the metal sheet material is a stainless steel material, wherein the at least one peening stream is generated from a peening material in which at least 50% by weight of the peening material has a largest particle diameter of at least 0.8 mm and wherein the metal sheet material has a mean final surface hardness after the application of the at least one peening stream of at least approximately 300 HV.
First claim
Opening claim text (preview).
The invention claimed is: 1. Method for hardening a metal sheet material, comprising the following: applying at least one peening stream to the metal sheet material, wherein at least one peening stream is applied, in each case, to a front side of the metal sheet material and a rear side of the metal sheet material, respectively, at least at times simultaneously; wherein the metal sheet material is a stainless steel material, wherein the at least one peening stream is generated from a peening material in which at least 50% by weight of the peening material has a largest particle diameter of at least 0.8 mm and wherein the metal sheet material has a mean final surface hardness after the application of the at least one peening stream of at least approximately 300 HV. 2. Method according to claim 1 , wherein a hotspot of a peening stream which is applied to the front side of the metal sheet material and a hotspot of a peening stream which is applied to the rear side of the metal sheet material overlap one another by at least 80%. 3. Method according to claim 1 , wherein the metal sheet material has a material thickness of not more than approximately 3 mm. 4. Method according to claim 1 , wherein the metal sheet material has a mean starting surface hardness before the application of the at least one peening stream of not more than approximately 200 HV. 5. Method according to claim 1 , wherein the at least one peening stream is generated from a peening material in which at least 50% by weight of the peening material has a largest particle diameter of not more than 1.0 mm. 6. Method according to claim 1 , wherein the metal sheet material is moved relative to the peening stream during the application of the at least one peening stream.
