Stainless Steel 347/347H Fasteners Manufacturer

Astec Tubes is a leading manufacturer, distributor, stockholder, and exporter of 347 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.
