Siliconsteel is one of the leading Stainless Steel 316l Flanges manufacturers and suppliers. We supply both ferrous and non-ferrous flanges throughout the globe. All types of standard Stainless-Steel flanges are made. Flanges from 316L Stainless Steel are one of the industry's most common flanges. We produce flanges that meet all industrial applications' requirements. We produce our flanges according to all international and quality requirements. Flanges of 317L Stainless Steel can be produced at different levels, requirements, sizes, and grades. We offer custom flanges that are well suited to our clients.

Stainless Steel 316L is a low-carbon molybdenum alloy of the Austenitic steel category. This alloy has a higher chromium content, nickel, which offers corrosion resistance. This grade has outstanding resistance to chemical attacks, including formic acids, acetic acids, citric acids, sulfuric acids, and other hard acids. This classification has a strong resistance to chemical attacks. The low carbon content also offers sensitization tolerance.

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.
