304L stainless steel / SS304L has an extra-low carbon content and is a variation of 304. The low carbon content is necessary for welding applications where avoiding carbide precipitation is key. Additionally, due to the low carbon content, 304L has lower mechanical properties than 304.
Shanghai Katalor enterprises Co., Ltd professionally sells 304L stainless steel with the lowest price. There are many steel types stock in our Shanghai warehouse, such as 304L steel plate, 304L steel pipe, 304L profile steel, 304L square/rectangle hollow section, 304L bar and so on.
304L stainless steel application
304L stainless steel is a kind of common stainless steel materials.
304 stainless steel is widely used to make for a good comprehensive performance, corrosion resistance and formability of equipment and parts. 304L is also known as ultra-low carbon stainless steel.
