Siliconsteel is a leading manufacturer and supplier of Duplex 2205 /31803 Flanges. We make flanges using various metals and alloys. We use UNS 31803 and UNS 32205, respectively, in Duplex Material. Duplex 31803 is the most common grade used in duplex containing 4% molybdenum, 25% chrome, and 7% nickel alloy. It has high mechanical strength and provides excellent resistance to stress cracking, chloride corrosion, and cracking. Duplex 32205 consists of 22% chromium, 3% molybdenum and 5-6% nickel. Two phases of corroded metal, ideal for applications requiring excellent resistance to corrosion and strength.

Ferritic-Austenitic Steel grades 32205 and 31803 are suitable in many applications and operations where superior corrosion resistance is needed. Duplex S31803 / S32205 Flanges is the best standard we sell in the world market. Such flanges are manufactured in many specializations such as class, size range, regular, finishing on surfaces, weight, the thickness of the sheet, and surface finish. We also supply custom flanges according to customer requirements. To support applications such as petrochemicals, power generation, gas processing, chemical equipment, pharmaceutical, and seawater, we supply a wider variety of our high-quality S31803 / s32205, flanges. Our Flanges Duplex S31803 / S32205 are the most common items on the market. Thanks to the price and characteristics of Flanges, they are available to our customers on request.

Our Duplex S31803 / S32205 Flanges characteristics include high strength, high solderability, workability, quality control, chloride stress cracking resistance, corrosion in general, chloride flaking, and slit corrosion, etc. We aim to fulfill the needs and desires of our customers. In the defined time, we concentrate on providing the right solution for our customers. Duplex 2205-s31803 flanges are made up of an alloy that has a longer life and is also cost-effective. Ferritic and Austenitic both are the base that makes up this alloy. There, they bear all the properties that these two elements possess. These flanges have high tensile strength. In addition to the strength, it is also highly resistant to oxidation and the environment that can cause corrosion.

Duplex 2205-s31803 flanges also have excellent resistance to corrosion in environments containing various acidic elements such as sulphuric acid and chlorine. These flanges can stand a temperature up to 300 degrees celsius. If the temperature is raised above the given temperature, it might lead to the embrittlement of the flanges. These also have the property of being ductile and can even show this property at a low temperature. These flanges can also be made harder by undergoing heat treatment. As these flanges have a higher content of chromium than the other stainless steel alloys and can also withstand chlorine, it is widely used in marine and off the shore environments.

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.
