<p>The invention provides a method for the continuous manufacture of ferritic stainless steel bands suitable for use in environments with frequent changes in temperature. It has been found preferable to have such band longitudinally displaced through a coating chamber wherein the band is provided with a coating of aluminum that is deposited thereon by means of physical vapor deposition technology during a time period sufficient so that aluminum becomes evenly distributed in the ferrite, after which a homogenization occurs at 950-1150 °C.</p> |
