304H Stainless Steel Pipes and Tubes Manufacturer, Stockholder And Supplier
() is a modification of the most widely utilized “18-8” chromium-nickel austenitic stainless steel. The carbon content is controlled in the range of 0.04-0.10% for increased strength at temperatures above 800°F (427°C). It is an economical and versatile corrosion resistant alloy suitable for a wide range of general purpose applications.
It is common practice for to be dual certified as 304 and 304H. The high carbon chemistry of 304H enables 304 to meet the Mechanical Properties and grain size requirements of 304H.
has general corrosion resistance similar to 304/304L. It resists atmospheric corrosion, as well as, moderately oxidizing and reducing environments. However, because of its high carbon content, Alloy 304/304H is subject to carbide precipitation in the heat affected zone of welds.
Alloy 304/304H is non-magnetic in the annealed condition, but can become slightly magnetic as a result of cold working or welding. It can be easily welded and processed by standard shop fabrication practices.
