4 Types of Steel: What are their differences?

Here are the four main different types of steel: 1. Carbon Steel. Carbon steel is named as such due to its higher carbon concentration. It contains higher C and minimal traces of other elements, making carbon steel simple but very durable. Generally, many regard carbon steel to be the strongest steel type. This is why components that need to be ...

Killed steels are characterized by a high degree of chemical homogeneity and freedom from porosity. We say the steel is "killed" because it will quietly solidify in the mould, with no gas bubbling out. As a result, killed steel is dense in structure, uniform in composition, and not so segregative as other types of steels. Background
