Product details
Gnee Steel Group is one of the recognized suppliers and exporters in the 304H Stainless Steel Tubes and Tubes market, where 18% of the minimum chromium content in it provides corrosion and oxidation resistance and must also contain at least 10.5 percent chromium. Depending on the grade, it may contain much higher chromium levels and additional alloy ingredients such as molybdenum, nickel, titanium, aluminum, copper, nitrogen, phosphorus and selenium. 304H alloy is a general purpose austenitic stainless steel with a cubic structure of centered faces. It is essentially non-magnetic in annealed state and can only harden cold. Its low carbon content compared to alloy 302 provides better corrosion resistance in welded structures.
Stainless steel 304H alloy (UNS S30409) is a variation of the austenitic 304 Alloy with 18% chromium and 8% nickel, in which the carbon content is controlled within a range of 0.04 to 0.10 to provide greater resistance to high temperatures to parts exposed to temperatures above 800oF. This alloy can be considered for a wide variety of applications and features an excellent combination of corrosion resistance and machinability. Each alloy represents an excellent combination of corrosion resistance and fabricability. This combination of properties is the reason for the widespread use of these alloys that account for nearly half of total U.S. stainless steel production.
