What is CRGO silicon steel?
CRGO is the abbreviation for Cold Rolled Grain Oriented Steel, which is used in particular to laminate any heavy transformer as a core. CRGO steel has exceptionally high mechanical elasticity and magnetic properties in the rolling direction. In general, CRGO steel cores come in a normal range of 0.3 mm to 0.25 mm.
What is Crngo?
CRNGO: Cold Rolled Non-Oriented Electrical Steel (Non-Oriented Electrical Steel) The term oriented, when used in conjunction with electrical steels, refers to a crystal structure having magnetic properties that are materially better in a given direction.
What is the difference between CRGO and Crngo?
CRGO & CRNO are both electrical steel grades used for stampings & cores of electrical Transformers & other electrical appliances. CRNGO Non oriented fully processed steels are iron-silicon alloys with varying silicon contents and have similar magnetic properties in all directions in the plan of the sheet.
Is silicon good for steel?
Silicon increases strength and hardness but to a lesser extent than manganese. It is one of the principal deoxidizers used in the making of steels to improve soundness, i.e. to be free from defects, decays or damages. Silicon is present in all steels to a certain extent.
What is silicon steel used for?
Silicon steel is a soft magnetic material that is used in electrical power transformers, motors and generators. It has a high silicon content of about 3.2 mass %, which increases the electrical resistivity of iron and, therefore, reduces eddy current losses.
Does silicon steel Magnetise easily?
Magnetostriction of Grain-Oriented 3%Si-Fe Grain Oriented (GO) Silicon Iron alloys are among the most popular soft ferromagnetic materials. They exhibit the so-called GOSS texture, and are widely used in high power transformers because of their very good magnetic properties along the rolling direction.
Why is silicon added to steel?
Silicon. Silicon is perhaps the most common alloying element in steel, as almost all steel requires silicon during the manufacturing process. Silicon helps to purify the iron ore during the smelting process by deoxidizing it and removing other impurities from it.
Why is silicon used in steel?
Si helps increase the strength and the hardness of the steel, but it is less effective than Mn in these functions. Si improves acid resistance and promotes large grain sizes, which cause increasing magnetic permeability. In alloy steel grades, Si also increases strength (but not plasticity) when quenched and tempered.
What does adding silicon to steel do?
What is the purpose of using silicon steel?
Why carbon is added to steel?
Carbon steel is an alloy of iron and carbon. In addition to brittleness, yield point, tensile strength and rusting are all affected by increased carbon concentration. Increasing carbon also reduces the weldability, especially above ~0.25% carbon. Plasticity and ductility are similar.

How is non grain oriented silicon steel ( GNO ) used?
Non-grain Oriented Silicon Steel (GNO). In the coming sections, we will discuss the GO steel. Specifically, we will discuss cold rolled grain oriented (CRGO) silicon steel and its applications. It is done to reduce the thickness of the steel in the range of 0.1 mm to 2 mm which cannot be achieved with hot rolling.
