304L is a versatile stainless steel, which is widely used to make equipment and parts that require good comprehensive performance (corrosion resistance and formability).
As a low-C 304 steel, its corrosion resistance is similar to that of 304 steel under normal conditions, but after welding or stress, its resistance to intergranular corrosion is excellent. It can also maintain good corrosion resistance without heat treatment, generally used below 400 (non-magnetic, use temperature -196 degrees Celsius to 800 degrees Celsius)
It is used in the chemical, coal, and petroleum industries that require high resistance to grain boundary corrosion, inside and outside the open-air machinery, building materials, heat-resistant parts, and parts that are difficult to heat treatment.
The development of 304L stainless steel has made the corrosion resistance, appearance, workability and strength of 304L stainless steel far exceed other materials. Moreover, many surface treatment methods of stainless steel can obtain a variety of colors and shapes. This is stainless steel. Development has made a great contribution.
304L is a variant of 304 stainless steel with lower carbon content and is used where welding is required. The lower carbon content minimizes the precipitation of carbides in the heat-affected zone near the weld, and the precipitation of carbides may cause stainless steel to produce intergranular corrosion (welding erosion) in certain environments.
