What is Stainless Steel 304/304H/304L Round bar ?

SS 304/304H/304L are the alloyed steel grade round bars with all superior mechanical and physical properties. SS 304 and 304L both are the lower carbon version alloy grade, on the other hand, SS 304H is high carbon version alloy that has up to 20% carbon proportion, making it one of the most premium and excellent products in the entire 304 family. Additionally, the non-carbon proportion in these materials includes composition of manganese 2-8%, silicon 0.10-0.75%, phosphorus 0.045%, sulfur 0.03%, chromium up to 18-20%, etc. SS 304/304H/304L round bars are combined with several good properties such as good thermal conductivity, density, stress-proof, elongation, electrical conductivity, and ultimate tensile strength like many properties. SS 304/304H/304L round bars and rods are constructed using some useful chemicals that are responsible for holding high resistance and good performance under hostile environments. Hence, SS 304/304H/304L is manufactured with ease of efforts all thanks to its chemical properties to provide high resistivity.

SS 304, 304L and 304H both grades are produced with the intensive finishing processes and get their desired dimensions and thicknesses as per the client’s demands. We offer all kinds of surface coating methods including black polish, Satin, and others. The forms of these products are available in Round, Rectangle, hex, forging, billet, and many more.
