The Introduction of Carbon Steel Casting and Elemental Analysis
Many people don't know what the carbon steel casting is and what the carbon steel is. Let me introduce to you. The carbon steel casting is a casting which using the carbon steel casting parts and other materials to mold. The carbon steel is composed of large number of carbon, small amounts of silicon, manganese, sulfur, phosphorus and other impurities.
According to the level of carbon content in thecarbon steel casting, carbon steel can be divided into low carbon steel, medium carbon steel and high carbon steel. Which one's carbon content is less than 0.25% is known as low-carbon steel. In the range of 0.25-0.6% is medium carbon steel. More than 0.6% is called high-carbon steel.
Among them carbon steel is the most used when is in carbon steel casting.
The content of carbon plays the important role in the quality of the products when carbon steel casting. You should know the content of chemical elements. The national standards are as follows:
1. The content of chemical elements: (Take C, S, Mn, P, Si, Cr, Ni as an example)
C: 0.010 ~ 6.000%; S: 0.0030 ~ 2.000%; Mn: 0.010 ~ 20.500%; P: 0.0005 ~ 1.0000%
Si: 0.010 ~ 18.000%; Cr: 0.010 ~ 38.000%; Ni: 0.010 ~ 48.000%; Mo: 0.010 ~ 7.00%; ΣRE: 0.0100 ~ 0.500%; Mg: 0.0100 ~ 0.800%; Cu: 0.010 ~ 8.000%; Ti : 0.010 ~ 5.000%
