ASTM A554 MT 316/316L

ASTM A554 MT 316/316L

ASTM A554 MT 316/316L SQUARE AND RECTANGULAR HOLLOW SECTIONS are premium-grade welded stainless steel mechanical tubing designed for demanding structural, architectural, and decorative applications. Manufactured in accordance with ASTM A554 standards, these hollow sections provide superior corrosion resistance, excellent dimensional accuracy, and high-quality surface finishes suitable for aggressive environments.

Grade 316 stainless steel contains molybdenum, which enhances resistance to pitting and crevice corrosion, especially in chloride-rich and marine environments. 316L is the low-carbon version that improves weldability and minimizes the risk of intergranular corrosion after welding. These square and rectangular hollow sections are ideal for projects requiring enhanced corrosion resistance along with structural strength and refined aesthetics.
