44W/50W/50WT are commodity mild steels under the Canadian engineering specification CSA G40.21. These grades are sometimes known by their metric equivalents 300W/350W/350WT. The HS 50W category may also include ASTM A572-50 (up to 4”), with minimum yield strength of 50ksi. We stock 50WT to Category 3, which has minimum reported CVNL impacts of 27J (20 ft lbs.) at -30C (-20F). All of our mild steel products are produced in North America or Europe.
We believe passionately in the spirit of collaboration. Every innovation and solution we develop is the result of working shoulder-to-shoulder with our clients. Find out how we can help answer your next challenge or engineering problem today.
