Pipe 20880

Electrotechnical plain steel 20880. Steel 20880 range. A form the sizes and maximum deviations by the amount of rolling of steel should conform to requirements: the form and the sizes of steel should conform to requirements: hot-rolled – GOST 2590-88, GOST 2591-88 and GOST 4405-75; shod – GOST 1133-71 and GOST 4405-75; calibrated – GOST 7417-75. Electrotechnical steel 20880 – the magnetically soft steel with special characteristics used for production of cores of the electrotechnical equipment (transformers, generators, electric motors, throttles, stabilizers, the relay, etc.) . Depending on the required level of magnetic properties electrotechnical steel contains different amount of silicon. Quality and a type of supply of steel 20880 corresponds: A high-quality and structural shape of B22 of GOST 1133-71, GOST 2590-2006, GOST 2591-2006 the High-quality and structural shape of B32 of GOST 7417-75, GOST 11036-75, TU 14-1-3606-83, TU 14-11-245-88, TU 14-1-1271-75 Sheets and strips of B33 of GOST 4405-75 of the Tape B34 TU 14-1-2822-79, TU 14-175-85-89 Electrotechnical plain steel 20880 – steel as a part of which the maintenance of basic elements should not exceed: on carbon – 0,04%, to silicon – 0,3%, to manganese – 0,3%. In the chemical composition steel 20880 contains chemical elements in %: With to 0,035 Si to 0,3 Mn to 0,3 S to 0,03 P to 0,02 Cu to 0,3 Fe ~ 99 Quality of electrotechnical steel 20880 are characterized by electromagnetic properties (specific losses, a coercive force and induction), isotropy of properties (a difference in values of properties of metal up and down of the direction of rolling), the geometrical sizes and quality of sheets and strips, mechanical properties, and also covering parameters. Physical, technology and mechanical properties of steel 20880: Hardness of material: HB 10-1 = 131 MPas Bondability of material: without restrictions. Electrotechnical steel 20880 is tried to be executed: with perhaps higher unit electrical resistance; with perhaps lower coercive force; with perhaps narrower loop of a hysteresis; with perhaps higher magnetic permeability. Electrotechnical plain steel 20880 is applied in magnetic chains of electric devices and devices. Electrotechnical steel 20880 is intended for production of cores of transformers, throttles, stators and rotors of dynamoes, different parts of electromagnetic devices and devices. Use of steel 20880 in the industry: for magnetic chains of electric devices and devices. Buy the Pipe 20880 legko:1. You send zayavku2. We expose to you schet3. You pay convenient for you sposobom4.
