1. Flange Specification:

2.304L Stainless Steel escription

Alloy 304/304H (UNS S30400/ S30409) 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 304H 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.

Alloy 304/304H 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.
