Stainless steel sheets are an iron-based alloy containing chromium and contain 10 to 12% chromium. Thanks to this feature, they are resistant to oxidation and are called stainless. Today, there are stainless steel types designed for many applications and uses. Product selection is made according to the temperature and strength conditions of stainless steel sheets. Thanks to its stainless and high temperature strength, it is modified and put into use. The surfaces of stainless steel sheets vary according to their degree classes, but they are generally smooth and smooth surfaces. For this reason, it can be used without the need for protection paint and can be matt or glossy. The quality of stainless steels cannot be distinguished by eye. However, a spectrometer device is used for quality measurements. Stainless steel sheet prices are determined according to production classes and grades. Since stainless steel is an expensive product, it is recycled in an almost infinite cycle. Approximately 85% of the products used in the world are recycled and 65% of the raw materials used in new manufacturing are recycled.
Stainless Steel Sheet Usage Areas
Thanks to their resistance to high temperatures, stainless steel sheets are widely used in the production of kitchen utensils and white goods, food, pharmaceutical and medical industries, automotive and aerospace industry, construction industry such as ventilation shafts, natural gas pipes, maintenance of production processes in the mining industry, photographic industry, petroleum and chemical fields, manufacturing of modular or welded water and food storage tanks such as milk and turnip, science and technology fields. Stainless steels, which are sensitive to chloride corrosion, should be kept away from humid environment conditions.
Factors Causing Rust
The mineral, which is found in nature as iron oxide, becomes a product after it is processed and separated. However, iron, which loses its natural form during production, starts to form oxide again with atmospheric air contact. This oxidation, i.e. burning, is called rusting. Another factor that causes this is moisture. When you prevent the combination of oxygen and moisture in air contact, rust formation will be very slow and in some cases there will be no rust.
Preventing Rust Formation
Coating with antirust or electrostatic paints, which will provide temporary protection. Galvanizing in zinc pools. This method will also provide temporary resistance. The amount of chromium in the iron content should be increased, that is, it should be increased to approximately %10-%12 levels,
Grades of Stainless Steel
While it is possible to classify it according to quite a lot of variable content values, the most common use in modular water tank production is 430 quality stainless steel, 304 quality stainless steel and 316 quality stainless steel.
