Astec Tubes are leading manufacturers, suppliers, stockists, and exporters of stainless Steel 347/347H Pipes in Mumbai, India. We manufacture these SS Pipes using high-quality raw materials and advanced technology under the guidance of professionals as per national and international quality standards. These Pipes are available in various types, standards, sizes and dimensions to meet the requirements of various industries. Stainless Steel 347 Pipes is a balanced, austenitic, chromium steel containing columbium which takes into consideration the end of carbide precipitation, and thus intergranular corrosion. SS 347 Pipe is balanced out by the increases of chromium and tantalum and offers higher creep and stress rupture properties than Alloy 304 and 304L, which may also be utilized for exposures where sensitization and intergranular corrosion are of concern. The expansion of columbium likewise permits Alloy 347 to have excellent resistance to corrosion. Stainless Steel 347H Pipes is the higher carbon composition form of Alloy 347and display enhanced high temperature and creep properties.

347 stainless steel pipe displays good general corrosion resistance that is similar to 304. It was produced for use in the chromium carbide precipitation scope by 800 – 1500 degrees F (427 – 816 degree C) where unbalanced alloys such as 304 are subject to intergranular attack. SS UNS S34700, S34709 Welded Pipes additionally performs somewhat superior to SS 321 in strongly oxidizing situations up to 1500 degrees F (816 degrees C). The alloy can be utilized as a part of nitric solutions; most diluted organic acids at moderate temperatures and in pure phosphoric acid at lower temperatures and up to 10% diluted solutions at high temperatures. 347 SS Pipes resists polythionic acid stress corrosion cracking in hydrocarbon service. It can also be used in chloride or fluoride-free caustic solutions at moderate temperatures. SS 347 Seamless Pipes doesn't perform well in chloride solutions, even in small concentrations, or in sulfuric acid.
