Specification of Stainless Steel 304 304L 304H Round Bars
SS 304/ 304l / 304H are types of stainless steel. Such stainless steels are one of the most commonly used. Other than iron, this steel contains nickel and chromium from 8 to 10% and 18 to 20% respectively. It is mostly non-magnetic in nature. These possess more corrosion resistance in comparison to normal steel. Such material is usually preferred in industries as it can withstand several corrosion environments. Environments where there are chances of crevice corrosion and also stress corrosion cracking. The difference between SS 304/ 304l / 304H is just based on carbon content. Where SS 304H contains approximately 0.04 to 0.10 % of the carbon that provides high-temperature strength to it. On the contrary, SS 304I contains only 0.03 % of carbon that prevents its sensitivity throughout welding.
SS 304/ 304l / 304H Round Bar is used in different industries because of its amazing properties and features. Industries include petrochemical industries, Oil and gas industries, power generation industry, paper and pulp industry, Sugar industry, Food processing industry, Offshore and onshore services and so on.
Moreover, for a better quality supply of SS 304/ 304l / 304H Round Bar, several tests and test certificates are performed and provided. Tests that are performed include PMI test, Mechanical test, radiographic test, destructive and non-destructive test, Flaring test, Micro and Macro test, etc.
