Benefits of Super Duplex SS Sheets


Super duplex stainless steel sheets are less expensive than commonly anticipated, particularly 304 stainless steel.


A special steel sheet is simple to clean.


Although a number of stainless steel types are magnetic, austenitic stainless steels are generally not.


Steel makers can blend this alloy into a precisely measured proportion of components and use this steel alloy to give sheets that are elastic and have unique properties. The thickness of the sheets varies, sometimes reaching a quarter of an inch.
