304L Stainless steel pipe
304L stainless steel has a very similar chemical composition to 304 stainless steel with one key difference. The maximum carbon content is set at 0.08% for 304, whereas grade 304L stainless steel has a maximum carbon content of 0.03%. It is more often adopted in the production of equipment and parts that require better corrosion resistance.

Product Show
304L stainless steel pipe is a variant of 304 stainless steel pipe with a lower carbon content and is often used in welding scenarios. The lower carbon content greatly reduces the precipitation of carbides in the heat-affected zone close to the weld, and the precipitation of carbides is associated with intergranular corrosion of stainless steel in certain environments. Basically, the need to anneal weld joints prior to using the completed metal form is not needed using 304L, saving time and effort. Generally speaking, both 304 and 304L stainless steel plates can be used for many of the same applications. The differences are often not significant enough that one is considered more useful over the other. 304L stainless steel plate is more commonly used in fields such as food processing equipment, building materials, automobile parts.
Surface Treatment
| Surface finish | Characteristics & Application |
| NO.1 | Hot-rolled surface, annealed and pickled, can be used as cold-rolling material, industrial tanks and chemical devices. |
| NO.2D | Cold-rolled, annealed and pick led with out skin passing the dull products can be used as auto mo bile parts, building materials and piping. |
| NO.2B | The surface brightness and flatness of NO.2B is better than NO.2D. Then through a special surface treatment to improve its chemical properties, NO.2B. could nearly satisfy comprehensive uses. |
| NO.3 | Polished with abrasive belt of grit #100#120, have better brightness with discontinuous coarse stria, used as inner and external ornaments for building, electrical appliances and kitchen utensils etc. |
| NO.4 | Polished with abrasive belt of grit #150#180, have better brightness with discontinuous coarse stria, but thinner than NO.3. are used as bathtub building inner and external ornaments electrical appliances, kitchen utensils and food processing equipment etc. |
| HL | Polished with abrasive belt of grit #150-320 on the No.4.finish and has continuous streaks, mainly used as building ornaments, elevators, door of building, frontal plate etc. |
| BA | Cold-rolled, bright annealed and skin passed, the product has excellent brightness and good reflexivity like mirror, used for electrical appliances, kitchen apparatus, ornament materials etc. |
