Steels in general have propertes lower carbon content than cast irons, and lower amounts of impurities like phosphorus and sulfur. However this is difficult to do with EN1A and is not recommended. Questions or comments about MatWeb? In general, properties such as density, thermal conductivity, and electrical resistivity do not vary greatly with composition or heat treatment, whereas properties such as tensile strength, elongation, and hardness are highly dependent on composition and heat treatment.


Generally as hardness and tensile strength goes up, elongation goes down. Values can range from – MPa, depending on composition and heat treatment. We advise that you only use the original value or one of its raw conversions in your calculations to minimize rounding error. The main advantage of cold drawn Steel is that Steel can be brought closer to the finished machine size, providing reduces machining costs.

When in its bright cold drawn condition the steel is able to endure higher levels of stress, particularly on smaller diameters.

EN1A Mild Steel

Due to the low carbon content of EN1A it is not recommended that this Mild Steel is used for welding. Mild Steel is used in mechanical engineering applications for parts that will not be subject to high stress. Varies widely with composition and heat treatment. Another benefit prooperties bright Steel bars is a marked increase in physical strength over hot rolled bars of the same section.


The term Mild Steel applies to all low carbon steel that does not contain any alloying elements in its makeup and has a carbon content that does not exceed 0. This Steel is especially good for free cutting, where a large volume of products are required.
