Alloy
304H Stainless Steel Sheet is a modification of Alloy 304 in which the carbon content is controlled to a range of 0.04-0.10 to provide improved high temperature strength to parts exposed to temperatures above 800°F.Alloy
304H Stainless Steel Sheet is also resistant to moderately aggressive organic acids such as acetic and reducing acids such as phosphoric. The alloy
304H Stainless Steel Sheet is covered by a variety of specifications and codes relating to, or regulating, construction or use of equipment manufactured from these alloys for specific conditions. Food and beverage, sanitary, cryogenic, and pressure-containing applications are examples.
