Stainless Steel 347/347H Fasteners Manufacturer

Stainless Steel 1.4550 Fasteners Supplier, Stainless Steel 347 Fasteners, Stainless Steel 347 Nuts, ASTM A194 SS 347 Fasteners Exporter, SS UNS S34700, S34709 Fastener Manufacturer, SS 347H Double Hex Bolt Suppliers in Mumbai, India.

Astec Tubes is a leading manufacturer, distributor, stockholder, and exporter of 347/347H Stainless Steel Fasteners in Mumbai, India. We produce these SS fasteners utilizing premium quality materials and modern technology under the supervision of professionals in accordance with national and international quality standards. These fasteners are available in different types, standards, sizes and dimensions to meet the requirements of different industries. Stainless Steel 347 Fasteners is a balanced, austenitic, columbium-containing chromium steel that takes into account carbide precipitation and therefore intergranular corrosion. We manufacture these SS Fasteners in various types such as nuts, bolts, screws, washers, studs, etc.

SS 347 Fastener is balanced by chromium and tantalum increases and provides better creep and stress rupture properties than Alloy 304 and 304L, which may often be used with exposures requiring sensitization and intergranular corrosion. Equally, the addition of columbium enables Alloy 347 to have outstanding corrosion resistance. Stainless Steel 347H Fasteners is the SS 347's higher carbon composition type which exhibit improved high temperature and creep properties.

347 stainless steel Fastener displays good general corrosion resistance, equivalent to 304. It was manufactured for use in the precipitation field of chromium carbide by 800 –1500 degrees F (427 –816 degrees C) in which unbalanced alloys such as 304 are subject to intergranular attack. In comparison, SS 347 Fasteners in highly oxidizing conditions up to 1500 degrees F (816 degrees C) perform far superior to SS 321.

The alloy can be used as part of nitric solutions; 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. 347 SS Fasteners are resistant to polythionic acid stress corrosion cracking in the hydrocarbon sector. It may also be found in caustic compounds free of chloride or fluoride at low temperatures. SS 347 Fasteners do not work well in chloride solutions, even in limited amounts or in sulphuric acid.

SS 347H Fasteners are used in a wide variety of uses including Chemical Manufacturing, Food Processing and Storage, Petroleum Refining Fluid Catalytic Cracking Systems, Polythionic Acid Service, Pharmaceutical Development, Waste Heat Recovery Systems, etc.
