<p>A strip of stainless, ferritic or austenitic steel or a titanium alloy produced by hot-rolling or casting is uncoiled and (if required) mechanically descaled. This is followed by chemical and/or electrochemical preliminary pickling, and concluded by cold-rolling to finish dimensions, with possible degreasing, annealing, finish-pickling, passivation, finishing and stretch-straightening. The method is characterised by the fact that preliminary pickling takes place with a solution containing hydrochloric, sulphuric and/or nitric acid.</p> |
