About Stainless Steel 347/347H Fasteners

Nissan Steel is one of the leading manufacturers, sellers, stockists, and exporters of 347 Stainless Steel Fasteners in Mumbai, India. Professionals ensure these SS fasteners meet national and international quality requirements by utilising high-grade materials and cutting-edge technologies. These fasteners come in various types, standards, sizes, and lengths to satisfy the requirements of various industries. Stainless Steel 347 Fasteners are balanced austenitic chromium steel with columbium that takes into account carbide precipitation and, as a result, intergranular corrosion. We produce a variety of SS Fasteners, including nuts, bolts, screws, washers, studs, and so on.

SS 347 Fasteners have the right quantity of chromium and tantalum and better creep and stress rupture qualities than Alloy 304 and 304L, utilised for sensitisation and intergranular corrosion. Columbium is added to Alloy 347 to increase its corrosion resistance. Stainless Steel 347H Fasteners comprise SS 347 with added carbon, which enhances its resistance to high temperatures and creep. A 347 stainless steel fastener has the same general resistance to corrosion as 304. It was designed for application in chromium carbide precipitation at 800–1500°F (427–816°C), in which imbalanced alloys such as 304 are susceptible to intergranular assault. SS 347 Fasteners exceed SS 321 in highly oxidising conditions up to 1500 degrees F. (816 degrees C).

The alloy works in nitric solutions, most diluted organic acids at moderate temperatures, pure phosphoric acid at lower temperatures, and up to 10% diluted solutions at high temperatures. It can also be found in acidic compounds without chloride or fluoride at low temperatures. Even in modest concentrations, chloride solutions and sulphuric acid don’t function with SS 347 Fasteners. Fasteners are utilised for various applications, including producing chemicals, processing and storage of food, petroleum refining fluid catalytic cracking systems, polythionic acid service, pharmaceutical development, and waste heat recovery systems, among others.
