ASTM A36 carbon structural steel


ASTM A36 carbon structural steel

EN 10025-2 is European standard, EN 10025-2 Carbon Steel is a steel alloy where carbon is the main alloying element.

Carbon steel can be grouped into 3 categories: Low Carbon Steel (also known as Mild Steel), Medium Carbon Steel and High Carbon Steel.

The machinability, strength and durability of A36 make it ideal for applications that require materials that are relatively light, but strong and durable enough to withstand high stress. These properties are crucial in materials used to construct infrastructure like buildings and bridges, where structural damage and failure could have devastating impacts.

Due to the popularity of A36 steel plate, Our keep a healthy inventory of a wide variety of plate sizes, making it easy to source. A36 is also one of the most economically priced grades of steel plate.

Applications & Industries:
Some of the common infrastructure applications for A36 include bridge and building construction.

A36 steel plate is typically used in structural applications due to its high strength-to-weight ratio and formability, as these properties make it easy to shape A36 into to a variety of structural pieces that can withstand great forces.

A36 Equivalent Plate Grades:
A36 steel is produced to meet standards set by ASTM, whose material standards are widely accepted in projects across the globe. However, some countries may require that structural projects which meets standards set by a different regulatory body. For example, structural projects that require plate falling under EN standards may use S275 in place of A36, as it is generally considered equivalent.
