Max Steels are the prestigious firm that is quite involved in proposing a huge variety of Alloy 20 Flanges. We are the manufacturer, supplier, and exporter of these flanges at domestic and global standard level. As we facilitate quality standard product at the market leading price. Therefore we make quality assurance product by using high quality of raw material and equipped the latest technical tools and machines to fetch out perfection. Thus our products are offered in precise shapes, thickness, and dimensions on the basis of requirements made by the customers. We make sure to provide full satisfaction to our customers as we facilitate great services to them.
These grades of flanges are made from nickel and copper content alloys also it includes some amount of columbium. These flanges have outstanding resistance to the crevice, pitting and general corrosion. Thus the copper alloy facilitates great protection against chloride and sulfuric acids. However, the presence of columbium helps in reducing the carbide precipitation during welding.
Our firm conducts stage wise testing and inspection procedure at various level of production. The test is like a tensile strength test, crevice and pitting resistance test, flattening test, micro, and macro test, third-party inspection and many more.
Documents such as fumigation certificates, guarantee letter, NABL approved laboratory test reports, quality assurance plan, raw material test reports, heat treatment charts and more. Such types of documents are given to our esteem patrons. We ensure quality packaging that provides protection from harm during shipping. We pack the product in wooden crates/cartons/boxes or in accordance to client’s constraints.
