EN 10341 Grade M1050-50K
EN 10341 Grade M1050-50K introduction
Semi-processed standard grade has guaranteed magnetic properties in accordance with EN 10341:2006 (which superseded EN 10126:1995 for non-alloyed grades and EN 10165:1995 for alloyed grades). The magnetic properties are developed during the final annealing cycle, which is performed by the client after punching the laminations. This annealing treatment reduces losses and improves permeability and polarisation, as a result of recrystallisation, grain growth and also - for certain grades - decarburisation.
The punchability of the semi-processed grade has been optimised by the application of an optimised final skin-pass reduction, after the cold rolling and annealing process. Skin-passing produces a controlled surface roughness, ensuring good material behaviour in the punching presses. This roughness also prevents the strips from sticking during the client’s final annealing treatment. Regarding magnetic performance, skin-passing also plays an important role by stimulating grain growth during the annealing cycle, which results in further reduction of losses and increased permeability of the steel.
