Silicon Steel Sheet
Silicon steel is a type of special steel that is composed of iron (Fe) and a small amount of silicon (Si). The low amount of silicon content in silicon steel gives it certain distinct properties, including a high permeability to magnetic fields and excellent mechanical properties. Silicon steel sheet also has a lower cost when compared to other ferrous steel alloys.
Silicon steel sheet is used in motors, generators, transformers, alternators and other electrical machines for its magnetic properties. The addition of silicon on its surface enhances the magnetic pertinence of the steel sheets. Silicon steel sheets are generally cold-rolled and annealed to improve their magnetic properties. These sheets may also be used for applications that do not require magnetic properties, such as the manufacturing of refrigerator shelves and furnaces, in automotive springs and in construction works.
Silicon steel sheet is a highly workable material and is available in different grades that are suitable for various applications. As a result, the sheet can be easily cut and shaped according to the requirements of a project. Depending on the grade and composition, the thickness of a silicon steel sheet can range from 0.1mm to 20mm. The types of grade vary depending on the customer’s needs, with some grades being 200 series, 300,500 or even 800 series.
The most common grades of silicon steel sheets are 30, 30HG, 33, and 35 grades. Grade 30 silicon steel sheets are the most common grade for producing electrical machines and appliances. These sheets are manufactured to meet different customer requirements and come in different grades depending on the application. Grade 30HG silicon steel sheets have a lower silicon content, which makes it an ideal choice for applications involving large magnetic fields, such as transformers and alternators. Grade 33 and 35 silicon steel sheets are used for more operatively demanding applications with higher stresses and temperatures.
Silicon steel sheets have excellent welding and forming capabilities, with some of the sheets having a 50% increase in strength after forming. Silicon steel sheets are generally corrosion resistant and have a good resistance to low temperatures and oxidation.
Silicon steel sheets are an ideal option for a wide range of applications. They provide an economical solution with excellent magnetic properties while also providing a high-strength material. It is also important to choose the right grade and thickness of silicon steel sheets to ensure that it is suitable for the task at hand.
