Kencotube is the Manufacturer & Stockiest of ASTM A276 Stainless Steel 304H Round Bars, which is the Most Widely Used Austenitic Stainless Steel Modified with a Controlled Carbon Chemistry for Increased Strength to 1500 Degree F (816 Degree C). ASTM A276 Stainless Steel 304H Bars are a modification of the most widely utilized "18-8" chromium-nickel austenitic stainless steel. ASTM A276 Stainless Steel 304H Rods has general corrosion resistance similar to Stainless Steel 304L. In most instances, the corrosion resistance of ASTM A276 SS 304H Round Bars will be roughly equal in most corrosive environments. However, in environments that are sufficiently corrosive to cause intergranular corrosion of welds and heat-affected zones ASTM A276 SS 304H Bars should be used. ASTM A276 SS 304H Rods resists atmospheric corrosion, as well as, moderately oxidizing and reducing environments.
However, because of its high carbon content, ASME SA276 Alloy 304H Round Bars is subject to carbide precipitation in the heat affected zone of welds.The carbon content in ASME SA276 Alloy 304H Bars is controlled in the range of 0.04-0.10 percent for increased strength at temperatures above 800 Degree F (427 Degree C). ASME SA276 Alloy 304H Rods is non-magnetic in the annealed condition, but can become slightly magnetic as a result of cold working or welding. Stainless Steel UNS S30409 Round Bars can be easily welded and processed by standard shop fabrication practices, where it performs well in fresh water service with low levels of chlorides.
