Duracorr®

Overview

Duracorr® is a low-cost, 12% chromium, dual-phase stainless steel product. 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 substantially more corrosion-resistant than weathering, painted or galvanized steels. Duracorr® Grade 50 is formable, weldable and exhibits good toughness. Also certified to SA / A 1010 (UNS 41003).
