Silicon steel

Concession products: The so-called "concession products" refer to defects such as "scratches" and "pitting" on the surface layer. The manufacturer declares that "the surface layer does not raise any quality objections", but provides a "quality certificate". The main performance indicators such as "magnetic sensitivity" and "iron loss" basically meet the material requirements. Due to defects in the surface layer, its price is lower than that of genuine products of the same variety, specification, and material. The "price difference" between genuine products and "concession products" is several hundred yuan/ton, and the "price difference" between individual Chinese brands is about a thousand yuan/ton. The main advantage of "concession products" is the lower price, which is suitable for the consumption level of small and medium-sized production enterprises. Therefore, low-grade cold-rolled silicon steel sheets are highly favored by small and medium-sized enterprises as their products are not of high quality, The production of "concession products" can meet the material requirements.
