Before introducing the difference and connection between gray iron and ductile iron, let’s first understand what is gray iron and what is nodular iron.
What is gray iron? Gray iron cast iron is a kind of cast iron, and internal carbon exists in flake graphite. The fracture is gray, so it is called gray iron for short.
What is nodular iron? Before pouring, a small amount of spheroidizing agents (such as magnesium, calcium and rare earth elements, etc.), graphite agents (such as ferrosilicon, silicon calcium alloy) are added to iron water to promote the presence of spheroidal graphite, which is called spheroidal graphite iron, also called spheroidal graphite iron.
After a formal understanding of gray iron and ductile iron, let us look at the difference and relationship between them. According to our experience, the links between the two can be embodied in the following aspects:
