Stainless Steel 430 - 1.4016

This data sheet applies to hot and cold-rolled sheets/plates and strips, semi-finished products, rods, wire, sections and bright products for general purpose.

Application

Rail and road vehicles, container building, warehouse and transport devices for the sugar industry, sound absorber, coal mining. The steel is resistant to intergranular corrosion.

1)Particular ranges of sulphur content may provide improvement of particular properties. For machinability a controlled sulphur content of 0.015 % to 0.030 % is recommended and permitted. For weldability, a controlled sulphur content of 0.008 % to 0.030 % is recommended and permitted. For polishability, a controlled sulphur content of 0.015 % max. is recommended.

Processing

Cold forming with low amount of deformation is easily feasible above room temperature. Sharp chamfers parallel to the direction of rolling have to be avoided. Sheets with greater thicknesses and/or higher amount of deformation should be preheated up to 200 - 400 °C. If applicable, a hot forming at 700 - 900 °C can be necessary. The corrosion resistance is affected by annealing colors, which occur after hot forming or welding, or scalings. These have to be removed by pickling (pickling solution), grinding or sand blasting. It is only allowed to use iron-free tools for these workings. Machining does not differ from machining of non-alloy carbon steels with comparable or corresponding strength.

Remark

According to DIN EN 10095, appendix D material 1.4016 is deemed to be heat resisting.
