    Air hardening hot work tool steel (H12 H13) For welded tube production H13 is used for rolls that contact the heat of the weld area. Its lower carbon content and other alloying elements provide uniform heat transfer within the roll but reduce the wearability factor. H13 rolls will need frequent regrinding.
