# Steel Materials

How to specify yield and ultimate strengths for materials involved in steel design.

**Steel Design > Steel Materials** opens the *Steel Materials* table. (This will list *any* materials that have been defined in the model, not just steel materials.)

![](https://3750289988-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FlRZtG5Ynp58kYzLHYbR7%2Fuploads%2Fgit-blob-d7b59e3d53a866d5258d2d82e2aca3f1ef30c0b9%2FSteel%20Materials.jpg?alt=media)

This table contains the materials that have been defined in **Tables > Materials**, but it lists their steel design related properties as opposed to their analysis properties. The purpose of this table is to specify values for yield strength and ultimate strength for any steel materials that are involved in a design.

{% hint style="success" %}
Tip: The materials have probably already been assigned to the members in order to get an analysis. So at this point, there is no need to Assign anything specific to members. It is only necessary to specify the material strength values for any materials that are actually involved in a steel design.
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.enercalc.com/e3d-training-manual/design/steel-design/steel-materials.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
