Accreditation Administration System:
Quality carbon structural steel is less than 0.8 % of the carbon carbon steel, the steel contained sulfur, phosphorus and non-metallic inclusions less than carbon steel , the more excellent mechanical properties . According to carbon content can be divided into three categories: low carbon steel (C ¡Ü 0.25%), medium carbon steel (C to 0.25-0.6 %) and high carbon (C> 0.6%); quality carbon structural steel by including Manganese were divided into normal manganese content ( Mn 0.25% -0.8 %) and high manganese content ( Mn 0.70% -1.20 %) group , which has better mechanical and processing properties.
