Stainless Steel Square Bar
Type 304/304L Stainless Steel Square Bar is a corrosion-resistant, solid bar with excellent strength and machinability. It is commonly used in structural components, machine parts, and architectural frameworks where durability and surface quality are critical.
Stainless Steel Square Bar is non-magnetic in the annealed condition and not hardenable by heat treatment, but it can be strengthened through cold working. This makes it a flexible option for industrial and fabrication uses.
Type 304L Stainless Square Bar features a low carbon content (0.03% max), which helps prevent carbide precipitation during welding. This ensures long-lasting corrosion resistance, especially in welded joints.
