Introduction
304 stainless steel coil is austenitic type, which is non-magnetic or weakly magnetic steel coil. 304 stainless steel coil is divided into austenitic stainless steel cold rolled coil and stainless steel hot rolled coil.
304 stainless steel (coil) plate features: beautiful surface and diversified use possibilities; Good corrosion resistance; Longer and more durable than ordinary steel; Good corrosion resistance; High temperature oxidation resistance and high strength, so it can resist fire; Good plasticity and welding performance. It has excellent rust and corrosion resistance, good intergranular corrosion resistance and good processing performance.
304L is a universal stainless steel, which is widely used to make equipment and parts requiring good comprehensive performance (corrosion resistance and formability).
The development of 304L stainless steel has made the corrosion resistance, appearance, processability, strength and other characteristics of 304L stainless steel far exceed those of other materials. Moreover, many surface treatment methods of stainless steel can obtain rich and colorful colors and shapes, which makes a great contribution to the development of stainless steel.
304L is a variant of 304 stainless steel with low carbon content, which is used for occasions requiring welding. The lower carbon content minimizes the precipitation of carbides in the heat affected zone near the weld, which may lead to intergranular corrosion (welding corrosion) of stainless steel in some environments.
