Table Of content

We are the leading manufacturers of Carbon Steel A36 Flanges globally, and we export, manufacture, and supply a high-quality range of these Carbon Steel A36 Flanges. Carbon steel A36 Flanges, also known as mild steel or low carbon steel, is mild steel with a carbon content of less than 0.3% by weight. Due to the low carbon content. Carbon steel A36 Flanges steel exhibits characteristics like good formability, welding, machinability, and ductility. Carbon steel A36 Flanges may also contain other elements like silicon, copper, manganese, phosphorus, sulfur, etc. The oxidation resistance of these flanges is likewise remarkable, making them perfect for use in a variety of pipe systems. Carbon Steel A36 Flanges are used in a variety of sectors, including architecture sectors for architectural uses such as buildings and other structures.

Also, this Carbon steel A36 Flange chemical composition depends on the type of product. As well, we supply these Flanges to our customers at custom specifications according to their needs and requirements. These Carbon Steel A36 Flanges have a low carbon content and offer excellent forming qualities. In addition to Iron and manganese, these Carbon Steel A36 Flanges also exhibit excellent resistance to stress cracks and warping under high-stress conditions. The oxidation resistance of these flanges is equally remarkable, making them perfect for use in a variety of pipe systems.

Our clients provide all the documents and test reports generated during the production and testing process at the time of delivery together with the product details, a standard packaging method is used. We also offer customized packaging to our clients. We guarantee safe transportation, using fast and reliable modes of transport to ensure timely delivery of flanges worldwide.
