WHAT IS A36 STEEL PLATE?

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.

ASTM A36 steel is one of the most widely used carbon structural steels, although the carbon content of A36 material is maximum 0.29%, it is considered to be the mild steel (content of carbon ≤ 0.25%).

A36 mild steel is often compared to AISI 1018, A36 carbon steel is commonly hot rolled, while 1018 steel is commonly cold rolled.

Notes: There are two versions that define low carbon steel, one with a carbon content between 0.04% (0.05%) and 0.25% and the other with between 0.04% (0.05%) and 0.29%.

A36 material physical properties are given in the lists below:
Density: 7.85 g/cm3 (0.284 lb/in3)
Melting point: 1,425-1,538 °C (2,600-2,800 °F)

A36 Material Applications:
ASTM A36 structural steel has good weldability, it is usually hot rolled into rectangle steel, square steel, round steel, steel plate, and is also commonly made into all kinds of steel sections such as H beam, I beam, U channel, steel angle, steel tube, etc.
