Duracorr ®, a registered trademark of ArcelorMittal Steel, is a low-cost, 11% chromium, dual phase steel plate. When compared to weathering, painted or galvanized steels, it has life-cycle cost advantages that permit its effective use in a wide variety of applications. Duracorr ® is formable and weldable. It can be produced to 50 ksi minimum yield strength with good toughness.

Although less corrosion resistant than 300-series stainless steel grades, Duracorr ® is substantially more corrosion resistant than weathering, painted or galvanized steels. Duracorr ® develops a brown patina when used in non-abrasive, atmospheric conditions. Duracorr ® is listed in ASTM A240 as UNS designation S41003. The steel may be used in a number of applications requiring strength and corrosion resistance.

Duracorr ® Chemical Composition

Duracorr ®, is a registered trademark of ArcelorMittal Steel, is produced to the chemical composition shown below, and is melted and refined by the Vacuum Oxygen Decarburization (VOD) process. It exhibits a fine-grain, dual phase microstructure of ferrite plus tempered martensite.

Duracorr ® Processing

Duracorr ® exhibits a fine-grained microstructure of ferrite and tempered martensite that imparts attractive fabrication characteristics. Duracorr ® is formable and weldable when the guidelines below are followed.

Cold Forming

Due to its higher yield strength levels, Duracorr ® requires higher forming loads than mild steel-such as ASTM A36-during bending and other cold forming operations. It also exhibits slightly more spring-back.

When bending Duracorr ® with sawed, plasma-cut or ground edges, a 1/2t (t = thickness) minimum bend radius should be observed.

If the edges are sheared, the 1/2t radius only applies to bends perpendicular to the major rolling direction. Bends parallel to the major rolling direction should use a 2t minimum bend radius. The 1/2t guideline may be used for all orientations if the complete cold worked sheared edge (face and burr) in the location of the bend is ground removing approximately 0.05″.
