Stain with Relevance to Carbon Steel or Iron Denotes a Film of Ferric Oxide

Stain with relevance to carbon steel or iron denotes a film of ferric oxide that appears on the surface of iron in the form of rust. The atmospheric oxygen reacts with iron to form iron oxide that has larger molecules than that of iron and hence tend to be formed into flakes and fall away. This chemical process of oxidation causes surface corrosion, thus degrading the quality of steel. Chromium is a nobler metal and when applied on to the surface of steel, forms a passive film of chromium oxide that prevents further corrosion of surface. It also checks the spreading of corrosion into the internal structure of the metal. Due to the similarity of size of chromium oxide and steel, they bond firmly and stay attached to the surface. Stainless steel tube is an alloy of steel with chromium content varying within 10.5% to 11%. Due to their corrosion-resistance qualities even at very high temperature, stainless tubes find applicability in industries such as aviation, architectural, electronics, marine, air-conditioning and heating, medical, automotive and textile industries. Stainless steel tubes come in the form of seamless tubing or welded tubing. Seamless stainless tubes are further categorized as fractional, metric and imperial, according to their sizes. Welded stainless tubes come in fractional sizes to match to the convenience of the users. Stainless tubes can be manufactured to carter to the customized requirement with regard to structural, mechanical and general engineering purposes. Stainless tubes are preferred for applicability because of their strength of iron, anti-corrosive quality and an aesthetic look associated with smooth touching sensation. In the construction industry, stainless steel tubes have wide applicability in stair railings or guard railings. The aesthetic aspect of stainless steel tubing could be utilized for making a variety of designs and other kind of utility parts for prevention of accidents. Once polished to give a shining effect, the stainless steel tubing exhibits almost the same lustre with zero maintenance cost. Because of this quality, it finds wide application in interior decoration for making furniture and different kinds of home furnishing. Stainless steel tubing may also be used as protective storage for preservation of valuable documents and photographs. Because of the malleability for bending, stainless tubing is used in connecting gas pipes and also in the plumbing system. Galvanised Pipes and Tubes have almost similar characteristics of stainless tubes. These are dipped into a bath of molten zinc bath and a coating of zinc is put onto the surface of carbon steel or iron. Zinc being a nobler metal, it arrests the process of atmospheric oxidation on the surface of steel. Therefore, galvanized steel pipes find wide applicability in places where corrosion and rusting is required to be checked, such as in construction, power, process, ship, building, water, gas and sewerage, water wells and lancing tubes for various automotive and other industrial applications. Company manufacturing galvanised steel tubes pay due attention the quality of the products particularly the surface coating of zinc per square cm that contributes to the anti-corrosion quality of the steel tubes.
