United States of America – Marion

The Marion plant of ArcelorMittal, Tubular Products (formerly Dofasco Copperweld) manufactures as-welded mechanical tubing in a variety of steel grades to serve the automotive, boiler tube, conveyor roll markets and service centers.  The as-welded tubing is offered hot-rolled picked-and-oiled and cold-rolled.  It can be normalized for improved formability.  Our annual capacity is 72,000 tons.

Our as-welded mechanical product is produced from carbon steel manufactured to ASTM specification A513, as well as ASTM/ASME, A/SA 178 and A/SA 214.  Carbon steel is cost-effective and provides low to moderate strength and moderate to excellent formability.  It also offers generally excellent fabricating qualities such as welding or bending.

Also available are high-strength low-alloy (HSLA) grades, which offer a distinct advantage in strength/weight ratio that can result in reduced section weight and possible lower overall unit costs.  Strength levels from 40,000 through 90,000-psi minimum yield strength are available.
Marion as-welded mechanical tubing has excellent surface quality.  All tube is continuously stenciled and has a water-soluble synthetic rust preventative applied.

This facility also has some of the most extensive tube cutting capabilities in the industry.  Marion’s full size range can be cut to length in one of our six cutting centers.  Tolerances as close as +/-.030” are available.  Chamfering and wire brush de-burring of OD and ID surfaces are available.Our facility is certified as meeting ISO 9001 quality standards, as well as the auto industry’s demanding TS 16949 certification.ArcelorMittal Marion’s tubular products are found in a variety of end uses, including boiler tubes, conveyor rolls, agricultural, industrial and construction equipment.
