What is the difference between 304, 304H and 304L?Type 304 refers to those materials widely used in the manufacture of wire mesh, which contain 18% chromium or 8% nickel (18-8) on a stainless alloy basis, which will not rust when left outdoors and will not oxidize even when the temperature rises to
8k is actually a standard surface treatment of stainless steel. Stainless steel plate surface polishing and grinding, the surface is bright as a mirror, can shine things reflect people, called mirror 8k.We all know that stainless steel plate a chrome-nickel alloy steel, and 8k in the "8" refers to t
The common specifications of stainless steel wire mesh are 1mm-5mm, and the size of the mesh varies from 5cm-25cm. Stainless steel wire mesh specifications mainly from these three directions to see, respectively, mesh size, aperture, wire diameter, etc.. Common specification is the wire diameter, an

304/304L stainless steel sheet (UNS S30400/S30403) is the most widely used "18-8" chromium-nickel austenitic stainless steel. 304L is the lower carbon content of 304 stainless steel sheet. 304 stainless steel has a maximum carbon content range of 0.08%, while 304L has a max carbon content range of 0.03%. And the carbon content range in steel affects the corrosion resistance of tanks, so 304L stainless steel plate is a little better.

Best Price Cold Rolled AISI ASTM SS SUS 430 201 202 321 316 316L 304 Stainless Steel Sheet/Plate
Stainless steel does not stain, corrode, or rust as easily as regular carbon steel and provides high strength and impact resistance along with the aesthetic appeal. The material also has anti-bacterial qualities and is easy to clean and sanitize.
Stainless steel sheet and stainless steel plate are both a perfect solution for applications that require a durable metal with anti-oxidation qualities.
Surface finish | Characteristics & Application |
NO.1 | Hot-rolled surface,annealed and pickled,can be used as cold-rolling material,industial tanks and chem i cal devices. |
NO.2D | Cold-rolled, an nealed and pick led with out skinpassing the dull products can be used as automobile parts, building materrials and pipings. |
NO.2B | The surface brightness and flatness of NO.2B is better than NO.2D. Then through a special surfacetreament to improve its mechamical properties, N02B could nearly satisfy comprehensive uses. |
NO.3 | Polished with abra sive belt of grit #100#120,have bet ter bright ness with discontinuous coarse stria, used as in ner and ex ter nal or na ments for building, electrical appliances and kitchen uten sils 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 bathtud buildinginner 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 lectrical appliances, mirror, kitchen apparatus, or nament materials etc. |
