304L Cold Rolled Stainless Steel Sheet 2B Finish 0.5mm-6.0mm Low Carbon ASTM A240
304L cold rolled stainless steel sheet with 2B finish is a low carbon version of 304, offering the same corrosion resistance with improved weldability. The 2B finish is a bright, cold rolled, annealed and pickled surface that is smooth and uniform, suitable for most industrial and forming applications.
The low carbon content (max 0.030%) minimizes carbide precipitation during welding, making 304L the preferred choice for welded structures and equipment in the food, chemical and pharmaceutical industries.
