Siliconsteel is the manufacturer, retailer, and the exporter of flanges from Mumbai,India. Flanges SS 347 is one of the most common and requested flanges forms. We supply all the necessary components and items required. Flanges are one of the components for piping applications that we sell. We deliver a great solution to our customers with the excellent price and wide range of the SS 347 Flanges. We have supplied SS 347 Flanges with all properties required to facilitate the operation of any plumbing. In industries such as cement, chemical processes, and many more, we provide these high-end flanges.

Alloy 347 is Austenitic Chromium-Nickel steel stabilized by Columbium / Tantalum, with excellent weldability and unique qualities compared to traditional Austenitic Steels standards. The classification is resistant to corrosion at higher temperatures and best suitable for 450 degrees C to 900 degrees C environments. The alloy has characteristics such as high mechanical strength and promises high durability and long life. Alloy SS 347H contains between 0.04% and 0.10% Coal. This additional carbon increases the resistance to creep at higher temperatures. Such alloys are used primarily in high-temperature applications for corrosive conditions.

Applications :

These material are not a single material but the name for a family of corrosion resistant steels. Like many scientific breakthrough the origins of stainless steel lies in a lucky accident. From the smallest part of zipper to the largest building skyscraper, stainless steel is an essential part of modern life.Stainless steel’s strength, resistance to corrosion and low maintenance make it the ideal material for a wide range of applications. It is also has a long life cycle and is 100% recyclable.

Packaging Used By Us :

We ship our stainless steel metal products in industry leading packaging designed to ensure your order reaches its destination safely. We offer multiple packaging options to meet your specific requirements. Packing is quite important especially in a case of international shipments in which consignment pass through various channels to reach the ultimate destination, so we put special concern regarding packaging. We pack our goods in numerous ways based on the products. We pack our products in multiple ways.

Testing Used By Us :

To specify the various physical and mechanical properties of the finished product, various tests, both destructive and nondestructive, are performed. Metallurgical, hardness, hardenability, tension, ductility, compression, fatigue, impact, wear, corrosion, creep, machinability, radiography, magnetic particle, ultrasonic, and eddy current are some of the major tests that are performed by quality control personnel. Metallurgical testing is used to determine the quality of steel by analyzing the microstructure of a sample under a microscope. A cross section of a sample is first highly polished and then examined at a magnification from 100-500 diameters. The microstructure of steel consists of grains of different compositions and sizes.
