We shall take the following two factors into consideration when selecting steel, the one is the machinability of the steel, the other is the vervice character during the processing, we hope the steel has a low strength and high elongation, which make ti easy to cut, stamp or form. But in the service of steel, we hope it has high strength, good impact performance to suffer extreme service condition. For these two reasons, we should select suitable steel form its mechanical properties.  Main Mechanical Properties Include Yield Strength  The yield strength or yield point of a material is defined in engineering and materias science as the stress at which a material begins to deform plastically. Prior to the yield point the material will deform elastically and will return to its orignal shape whem the applied stress is removed. Once the yield point is passed some fraction of the deformation will be permanent  and non-reversible.  Tensile Strength Tensile strength is indicated by the maximum stress before the break of specimen. In general, it indicates when necking will occur.  Elongation  Elongation , or percent elongation at break, is defined as  the change in gauge length after break per unit of the original gauge length. A high enlongation means the material can stand great permanet deformation before break, or high deformability.   The parameter yield strength, tensile strength, enlongation are measured by tensile test.  Impact Energy Impact energy, or toughness, is determined by the energy absorbed by the specimen during fracture in the impact test. It is measured in units of joules. Impact energy indicates material's resistance to impact load. It is tested by charpy V-notch test.  If welding is required during the process, we should consider the welding performance of the steel.  Welding  For the steel, welding is a fabrication to combine different pieces of steel together. In the welding, normally the binding sites melt together and cool to form a strong joint, such as electric arc welding, gas welding and electric resistance welding.  Weldability Weldability, also known as joinablility, of a material refiers to its alibityy to be welded. Most steels can be welded,but some are easier to weld than others. It greatly influences weld quality and is an important factor in choosing which welding process to use.   

In the global era advocating green energy efficiency, top-grade silicon steel, with outstanding low loss and high magnetic properties, has become a key material driving efficient energy use. In the top ten fields, it plays an irreplaceable role, with its application in the new energy vehicle sector particularly shining.   The primary power source of new energy vehicles—the drive motor—demands stringent material performance. The low iron loss characteristic of top-grade silicon steel significantly reduces energy loss during high-frequency motor operation. Calculations show that a drive motor manufactured using top-grade silicon steel can increase energy conversion efficiency by around 15%. This means that with the same amount of electricity, a vehicle can travel a longer distance. For instance, in the case of a pure electric vehicle with a range of 500 kilometers, using a drive motor made of top-grade electrical steel can increase the range by about 75 kilometers. Furthermore, the excellent magnetic performance of top-grade silicon steel ensures a more uniform distribution of the motor's magnetic field, reducing operational noise and prolonging the motor's lifespan.

Laminated cores play a crucial role in electrical equipment. They are made by stacking thin silicon steel sheets or ferroalloy sheets and insulating them from each other. Its main purpose is to reduce eddy current losses and improve equipment efficiency. Take a transformer as an example. When alternating magnetic flux passes through the core, an induced electromotive force is generated. If the core is solid, a large eddy current will be formed, resulting in energy loss and core heating. The laminated core divides the core into thin sheets, confining the eddy current within a narrow circuit. The net electromotive force of the circuit is small, and the resistivity of the thin sheet material is high, effectively reducing the eddy current loss. In addition, laminated iron cores can also improve the magnetic field distribution, enhance the electromagnetic performance of the equipment, increase operational stability, and extend the service life of the equipment. In an electric motor, laminated cores are equally important. It helps to reduce energy loss, improve motor efficiency, and enable the motor to convert electrical energy into mechanical energy more efficiently during operation. At the same time, it can also reduce the noise and vibration during the operation of the motor and improve the overall performance of the equipment.

Transformer is a device that converts AC voltage, current and impedance. When AC current flows through the primary coil, AC magnetic flux is generated in the iron core (or magnetic core), causing voltage (or current) to be induced in the secondary coil. A transformer consists of an iron core (or magnetic core) and a coil. The transformer core is the main magnetic circuit of the coupled magnetic flux in the transformer. Working principle of transformer core The function of the core of the transformer is to form a magnetic circuit of coupling flux with very small reluctance. Because the reluctance is very small, the working efficiency of the transformer is greatly improved. Broadly speaking, transformers are divided according to the coupling material between coils, including air core transformers, magnetic core transformers, and iron core transformers. Air core transformers and magnetic core transformers are mostly used in high frequency electronic circuits. Because silicon steel itself is a material with strong magnetic permeability, it can produce greater magnetic induction intensity in the energized coil, which can reduce the size of the transformer and improve the working efficiency of the transformer. The characteristic of silicon steel is that it has the highest saturation magnetic induction intensity (above 2.0T) among commonly used soft magnetic materials. Therefore, when used as a transformer core, it can work at a very high operating point (such as an operating magnetic induction value of 1.5T). However, silicon steel also has the largest iron loss among commonly used soft magnetic materials. In order to prevent the iron core from heating due to excessive losses, its frequency of use is not high and it generally can only work below 20KHz. Therefore, the frequency of power circuits is mostly Around 50Hz.
