🟧 Product Overview
Austenitic stainless steel coils are the most widely used stainless steel family, characterized by:
Excellent corrosion resistance
High ductility and formability
Non‑magnetic structure
Good weldability
Superior performance in low and high temperatures
Grades such as 304, 316L, 321, 310S are industry standards for food processing, chemical equipment, heat exchangers, and high‑temperature applications.
🟧 Available Grades
201, 202, 301, 302, 303, 304, 304L, 305, 309, 309S, 310S, 316, 316L, 316Ti, 317L, 321, 330, 347
