Navgraha Steel & Engg Company offers SS 347 flanges. Stainless Steel alloys are preferred over other alloys because of their tensile strength and sturdiness. SS 347 flanges have such attributes and qualities in them. SS 347 flanges are not heavy weighted and hence the cost of fabrication is less. It comes with the diameter of the hub, thickness of the flange, number of bolts used, diameter of bolts and their holes, etc. They are feasible and readily available in the market. They have thermal conductivity up to certain bearable temperatures. Such flanges show high melting ranges.
Why is stainless Steel considered to be the best?
SS 347 is like the SS 321, and it is normally utilized as a balanced out option to Type 304, where 347 is balanced by columbium. It is known as general-purpose steel and obtained with an Austenitic structure. It is described as non-magnetic and suppresses Chromium carbide formation due to columbium. It is recommended to cold hardening.
• They fight corrosion.
• Can deal with chemicals easily.
• Provides the ease of cleaning and maintaining conveniently.
• They are cost-effective.
• They are considered to be sterile.
• They are resistant to fire and heat too.
SS 347 flanges have all such qualities in addition to the features of flanges.
Chemical factors of SS 347 flanges:-
• Chromium makes the product tougher
• Nickel increases the resistivity of the product.
• Manganese which brings out more yield.
• Phosphorous is helpful in increasing the longevity of the flanges.
• There are traces of carbon, silicon too.
Stainless Steel 347 flanges can work well with extremely elevated temperatures. They support applications where wear and tear are often experienced. Having nickel and chromium in their composition makes them combat oxidation. Their excellent strength in terms of mechanical properties makes them fit for heavy exhaust systems. Such flanges are available in specifications of ASTM A182 and A240. Such flanges can be forged, applied with high-temperature service, and rolled for more robustness. These flanges have minimal bores or diameters. The perforations made on their flat face gives ease of attaching to machines.
Where are SS 347 flanges used?
SS 347 flanges are used in the chemical industry, oil and pipeline units, general-purpose applications, fabrication plants, and structural pipes.
