They are called PowerCore AP Grades and designated by suffix AP .Magnetic properties in all directions are significant for PowerCore AP grades. We achieve this by means of a special manufacturing technology which results in an advantageous isotropic texture in all directions in the plane of the sheet. At medium field strength PowerCore AP grades can be more readily magnetized resulting into increased magnetic PowerCore polarization value (permea-bility).PowerCore AP grades offer decisive advantages especially for higher field strength, mini motors in the field of application up to 200 Hz and medium sized motors for which a good heat conducti-vity of the steel sheet is important. For ballasts, these grades ena-ble a higher rated working induction. In general, AP PowerCore grades help in downsizing the motor and reduce the overall cost of electrical equipment due to reduced consumption of copper as well as following points are note worthy for PowerCore AP grades:- For a given core loss, these steels exhibit substantially higher magnetic polarization values (by about 3-8 %) than standard non grain oriented fully processed grades- Permeability at T is higher by more than 30 % over standard PowerCore non grain oriented fully processed gradesFor grades other than mentioned above please enquire separately.

PowerCore PP grades optimize two related charac-teristics of various electrical steels which are important for the designer: the low core loss of high alloyed grades and the high magnetic polarization of low alloyed grades. A strongly developed texture provides especially good longitudinal and transverse magnetic properties. PowerCore PP grades are supplied in pre decarburized condition with anti stick weldable insulation PP grades develop final magnetic properties after stress relief annealing (in controlled atmosphere) of laminations and decarburization annealing is avoided. PowerCore PP grades offers better punchability over standard semi processed grades even on alloy steel tools due to lower yield strength to tensile strength ratio and insulation coating. PP grades are ideal choice for energy efficient motors and motors for home appliances work-ing at medium field grades other than mentioned above please enquire separately.

Presences of organic parts ensure improved punch and die life during stamping operations. During annealing, the organic part of the coating vo-latilizes but inorganic part remains to provide an adherent film with a high level of surface resistivity. No significant flaking occurs at the punched edges of laminations. Significant punchability improvement (min 2 times of bare steel) & adequate surface insulation resistance despite low coating thickness are obtained with this type of coa-tings. Used for refrigerator motors, small to large sized motor. C6W coatings are useful for small and medium sized motors where high temperature resistance and weldability are : It is a pigmented organic coating. It displays good weldablity and punchability at low coating thickness. It offers good corrosion protection and high elevated temperature strength.
