This window is displayed when you press the ‘...’ button on either the Material tab of the Options window, or on the Section tab of the Section Inputs window. If you came from the Options window, you are defining the default material for new sections; it does not affect any existing sections. If you came from the Section Inputs window, you are defining the material for the current section only.
This tab will appear if the original material was a carbon steel. See also Stainless Steel Tab.
| Material Type | The designation for the type of material of the section. |
| Modulus of Elasticity, E | AISI specifies this value to be 29500 ksi or 203,000 MPa for carbon steel. |
| Minimum Yield Strength | The minimum value of yield strength for this type of carbon steel. |
| Default Yield Strength | The default value of yield strength when using this type of carbon steel (usually the minimum yield strength). |
| Minimum Tensile Strength | The minimum value of tensile strength for this type of carbon steel. This also is used as a maximum value of yield strength. |
| Default Tensile Strength | The default value of tensile strength when using this type of carbon steel (usually the minimum tensile strength). |
| Maximum Tensile Strength | The maximum value of tensile strength for this type of carbon steel. |
| Minimum Elongation in 2 inches (%) | The specified minimum elongation in a 2 inch (50 mm) gage length standard test specimen. This is used to determine whether a lower yield stress is required for design. |
| Minimum thickness for this elongation | The minimum thickness for which the above elongation is applicable. If the elongation is applicable to any thickness, enter 0. |
| Min elongation for thinner steel (%) | For steel thinner than the minimum entered above, enter the specified minimum elongation in a 2 inch (50 mm) gage length standard test specimen. |
| Default Button | This button sets the material to the current default settings for the new sections (defined in the Options window). |
| Customize Button | This button allows you to customize the material currently being displayed. You may modify the name of the material, but CFS will always place the name inside brackets to identify it as a material not originally provided with CFS. You may also modify any of the numerical inputs, with some limitations imposed by CFS. The customized material will then become your default material for new sections. |
