The Swedish company SSAB Oxelösund claims to be the first in the world to guarantee the precision of their AccuRollTech rolled steel plate. The guarantee covers thickness tolerances and applies both to ordinary steel and the Hardox and Weldox grades, in plate dimensions from 4 mm to 150 mm. These close thickness tolerances for rolled plate have been made possible by means of a new and advanced four-high rolling mill. "Today we can produce plate with a thickness tolerance down to +/-0.2 mm", says Johan Anderson, Business Development Manager for the company. Such close tolerances save weight and material, and have many other advantages too.
