Silicon Steels is a well-known supplier, exporter and manufacturer of Duplex Steel 2205 Bars And UNS S31803 Duplex Round Bars in Mumbai India. Duplex Steel UNS S32205 Bars are used for several applications, including chemical plant containers, piping and heat exchangers; pulp mill digesters, bleach washers, pre-steaming containers; food processing equipment; oil field piping and heat exchangers; natural gas desulfurizing equipment; and more. Duplex Steel 2205 Round Bar is also considered a workhorse grade since the alloy is the most commonly used grade in the stainless steel duplex. The benefit of having a dual or duplex microstructure is that the Duplex Steel Uns S31803 Round Bar has a mixture of ferrite alloy qualities but desirable. Duplex UNS S32205 Hollow Bars have excellent workability, high corrosion fatigue resistance and so on.
Duplex 2205 Round bars are excellent for localized corrosion, including inter granular corrosion, stitching and cracking. The S32205 Duplex Polished Bar is also called the work horse standard because the alloy is the most widely used type of stainless steel duplex grade. The downside of the dual or duplex micro systems is that the Astm A276 2205 Hot Rolled Bar has mixed, while advantageous properties of a ferritic steel, i.e. corrosion cracking and stress based resistance with austenitic type steel, i.e. fast processing and corrosion tolerance.

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.
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.
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.
