1. What is the difference between Cast iron and Cast steel?
The difference between Cast iron and Cast steel is their carbon content. Cast Iron with carbon content greater than 2.06% is iron; steel with carbon content between 0.02% and 2.06% is steel.
2. What is carbon steel? How many categories does it fall into?
An alloy of carbon and iron (when the carbon content is between 0.02% and 2.06%) is called carbon steel. According to the different carbon content, carbon steel is divided into three categories:
A. Low carbon steel-C <0.25%;
B. Medium carbon steel-C = 0.25%-0.60%;
C. High carbon steel-C> 0.60%.
In carbon steel, due to the different sulfur and phosphorus content, it can be divided into:
A. Ordinary carbon steel-P≤0.045%, S≤0.050%;
B. High-quality carbon steel-P≤0.040%, S≤0.040%;
C. High-quality high-quality carbon steel-P≤0.035%, S≤0.030%.
