ASTM A36 is said to be same as EN S275 steel plate. A36 steel is a very low carbon steel that blends great strength with form ability. It can be safely welded with minimum caution. This structural steel plate can be galvanized to give enhanced corrosion resistance which ensures superior quality.
The ASTM A36 specification is the Standard Specification for Carbon Structural Steel.ASTM A36 steel plate is one of the most widely used carbon structural steels used in the industry. It can be riveted, bolted or welded in the construction of bridges and buildings, and for general structural purposes.
ASTM A36 belongs to general low carbon steel, steel product with low carbon content less than 0.3%，it is considerably soft for easy forming, machining, welding. Heat treatment has less effect on ASTM A36 steel material. It contains some other elements including alloy element: manganese, sulfur, phosphorus and silicon. Iron and these elements together forms unique mechanical property of ASTM A36, unlike stainless steel with nickel and chromium element, it doesn’t show good corrosion resistance. If you need corrosion resistant property, having it painted with a layer of plating is a good choice.

Qualified A36 steel product shall have ultimate tensile strengths ranges from 58,000 to 79,800 psi. It is not a exact number for it is affected by its chemical composition and production method. In tensile testing, ASTM A36 steel bar can elongate to around 20% of its original length. It also shows excellent impact strength at room temperature.
