Carbon and alloy steels

Carbon steels

• Classified as low, medium and high:

1. Low-carbon steel or mild steel, < 0.3%C, bolts, nuts and sheet plates.

2. Medium-carbon steel, 0.3% ~ 0.6%C, machinery, automotive and agricultural equipment.

3. High-carbon steel, > 0.60% C, springs, cutlery, cable.

Benefits of Structural Steel

Some benefits associated with use of structural steel for owners are:

• Steel allows for reduced frame construction time and the ability to construct

in all seasons

• Steel makes large spans and bay sizes possible, providing more flexibility for

owners

• Steel is easier to modify and reinforce if architectural changes are made to a

facility over its life

• Steel is lightweight and can reduce foundation costs

• Steel is durable, long-lasting and recyclable (AISC 1999)
