Processing / Welding
Standard welding processes for this steel grade are:
- TIG-Welding
- MAG-Welding Solid Wire
- Arc Welding (E)
Processing
Cold forming with a small degree of deformation is easily feasble at tempertaure higher than room temperature. Sharp bending parallel to rolling direction should be avoided. Plates with larger thicknesses and/or higher degrees of deformation should be preheated up to 200 to 400°C. If applicable, hot forming at 700 to 900°C could be necessary. The corrosion resistance is affected by hot forming or annealing colours after welding or scaling. These have to be removed by pickling (pickling solution), grinding or sand blasting. Only iron-free tools are allowed for these workings. Machining does not differ from machining of unallyed carbon steels with comparable respectively corresponding strength.
