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.
