Metinox Overseas is the most reliable and trustworthy company of Stainless Steel Fitting supply in Srilanka – Colombo. We provide all the grades, types, and dimensions of the pipe and fittings globally. Stainless steel is the alloy in which there is maximum carbon content of less than 1.20%, and minimum chromium content of 10.5% or more.
It has excellent corrosion resistance and ductility. Because of the creation of a non-reactive chromium oxide coating that clings closely to the metal's surface, stainless steel remains corrosion resistant. This layer works as a barrier and defends metal from corrosion. Duplex/super duplex stainless steel, precipitation annealed stainless steel, martensitic stainless steel, ferritic stainless steel, and genuine stainless steel are some of the stainless steels that are utilized.
We offer and export various varieties of Stainless Steel Pipes in Sri Lanka - Colombo with reasonable SS pipe price. Stainless steel has several properties, including being hardenable by cold working, having a strong corrosion resistance at temperatures up to 1500 degrees Celsius, being non-magnetic in nature, and having a very significant cession resistance. It also has a lot of advantages such as improved strength, better ductility, a more appealing look, cheaper servicing costs, a faster wear resistance rate, and so on. As a result, stainless steel is frequently employed in the manufacture of pipe, tubes, and fittings across India.
For piping applications stainless steel is the common choice. Some high performance industries like engineering and aerospace has used stainless steel piping’s.. Depending on the applications and its requirements they can be formed in various types and sizes. Because of the durability and tensile strength stainless steel tube is preferred over other materials.
