Different types of steel are produced according to the properties required for their application, and various grading systems are used to distinguish steels based on these properties. According to the American Iron and Steel Institute (AISI), steels can be broadly categorized into four groups based on their chemical compositions:
- Carbon Steels
- Alloy Steels
- Stainless Steels
- Tool Steels
The following table lists the properties of steels based on the categories noted above. Properties determined at room temperature (77°F/25°C).
