# How can you get high density steel

Using screenshots, you can see how you can select the desired material in Comparial based on its physical properties.
If you click on the "Physical properties" field, you can enter temperatures, nominal thicknesses, delivery conditions and physical properties in the text fields.
In addition to the physical properties, Comparial offers you numerous information from standards that is important for calculations.

In general, the density of steel is 7.85–7.87 g / cm3 (7850–7870 kg / m3). But which type of steel has which density? Comparial offers you the specific weight of steel in a table - digital, simple and with a practical comparison function. Find out the raw density of all types of steel such as structural steel, stainless steel, free-cutting steel or spring steel.

### E-module steel - exact figures and comparison options

The material parameter modulus of elasticity describes the relationship between elongation and tension in materials such as steel. It is also known as the modulus of elasticity. With steel, the modulus of elasticity is between 200,000 N / mm² (e.g. with steel grade S210) and 220,000 N / mm² (e.g. with steel grade S220). The exact E-modules for individual types of steel can be found in the practical digital material database Comparial. Simply compare steel types and their E-modules (e.g. spring steel) and find the right material for your project.

### Coefficient of thermal expansion steel

The coefficient of thermal expansion describes the behavior of a material such as steel with regard to changes in its dimensions when the temperature changes. It is also called the coefficient of thermal expansion and differs depending on the material. A coefficient of thermal expansion of 11.7 is often given as a guide value for steel, but there may be major deviations depending on the type of steel. The coefficient of thermal expansion of stainless steel is different from that of other high-alloy steels. Comparial provides you with precise data on the coefficient of thermal expansion of steel in a digital table.
