|---|---|---|---|
Grade 304/304L is an austenitic stainless steel widely recognized for its excellent corrosion resistance, formability, and weldability. The “L” in 304L denotes a low carbon content (≤0.03%), which minimizes carbide precipitation during welding, making it ideal for welded components. Both grades are non-magnetic in the annealed state and exhibit high toughness across a wide temperature range. Common applications include food processing equipment, architectural panels, chemical containers, medical devices, and automotive trim. | |||
