304L stainless steel is a versatile stainless steel material. 304L is a variant of 304 stainless steel with a lower carbon content and is used where welding is required. 304L is made of stainless steel. This kind of steel has less carbide precipitated near the weld, which can reduce intergranular corrosion, so its ability to resist intergranular corrosion is relatively high. 304L stainless steel has good processing performance, good corrosion resistance and toughness, and its appearance and strength are far superior to other materials. It can be used to make some parts that require relatively high corrosion resistance and formability. Such as making open-air machines or building materials and heat-resistant parts in the chemical, coal, and petroleum fields.
