Description

Special steel
Special steel smelting process is more alloying elements added and taken to a special production, processing, steel chemical composition, structure and mechanical properties are better than the general steel. Its complexity is higher than the general grain steel, resulting in more applications, so in the higher quality requirements for steel areas to be extensive.
Classification
Press the technical content and quality of products, divided into high, medium and low three levels: First, high-quality carbon structural steel (carbon steel) based low-end steel products; Second, alloy steel (stainless steel, other than tool steel, high speed steel) as the representative of the end steel products; finally is stainless steel,  tool steel and high speed steel as the representative of the high-end steel products.
