Kencotube is well known production housefor ASTM A276 Stainless Steel 347 Round Bars, which is stabilized alloy andprovides as its prime benefit with an outstanding resistance to intergranular corrosion after exposure to tempin the chromium carbide precipitation range from 800 Degree F to 1500 Degree F (427 Degree C to 816 Degree C). ASTM A276 Stainless Steel 347 Bars is also advantageous for high temperature service because of its good mechanical properties. ASTM A276 Stainless Steel 347 Rods can be used in nitric solutions and most diluted organic acids at moderate temperatures and in pure phosphoric acid at lower temperatures and up to 10 percent diluted solutions at elevated temperatures.Working temperatures of 2100-2250 Degree F (1149-1232 Degree C) in ASTM A276 SS 347 Round Bars are recommended for forging, upsetting and other hot work processes.
ASTM A276 SS 347 Bars does not perform well in chloride solutions, even in small concentrations, or in sulfuric acid. ASME SA 276 Alloy 347 Round Bars must be water quenched or fully annealed after working to re-attain maximum corrosion resistance. ASME SA 276 Alloy 347 Bars does not harden by heat treating, whereelevated properties may only be obtained through cold reduction. ASME SA 276 Alloy 347 Rods can be easily welded and processed by standard shop fabrication practices. Stainless Steel UNS S34700 Round Bars has application such as high temperature gaskets and expansion joints, rocket engine parts, aircraft collector rings and exhaust manifolds and chemical production equipment.
