and treated and how it responds to loads and environmental conditions. This
chapter reviews steel production, the iron-carbon phase diagram, heat treat-
ment, steel alloys, structural steel, steel fasteners, and reinforcing steel. The
chapter also presents common tests used to characterize the mechanical
properties of steel. The topics of welding and corrosion of steel are also
introduced.
3.1
Steel Production
The overall process of steel production is shown in Figure 3.3. This process
consists of the following three phases:
1. reducing iron ore to pig iron
2. refining pig iron to steel
3. forming the steel into products
The materials used to produce pig iron are coal, limestone, and iron ore.
The coal, after transformation to coke, supplies carbon used to reduce iron
