ASTM A240 304H Steel Plate Sheet, Alloy 304H Plate, 304H Stainless Steel Plate, Cold Rolled Steel Sheet 2B Surface 304H Plate, UNS S30409 Plate, 1.4948 Plate.

ASTM A240 304H Steel Plate Sheet is made of 304H, the 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). Alloy 304H Plate is an economical and versatile corrosion resistant alloy suitable for a wide range of general purpose applications.

The high carbon chemistry of 304H enables 304 to meet the mechanical properties and grain size requirements of 304H. 304H Stainless Steel Plate has general corrosion resistance similar to 304/304L. Cold Rolled Steel Sheet 2B Surface 304H Plate 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.

ASTM A240 304H Steel Plate Sheet is made of the non-magnetic steel in the annealed condition, but can become slightly magnetic as a result of cold working or welding. ASTM A240 Stainless Steel Plate Sheet can be easily welded and processed by standard shop fabrication practices.
