What material is A36 steel

Chemical composition and function of A36 steel

A36 steel is a low carbon steel with a carbon content of less than 0.3%, which allows A36 steel to be easily machined, welded and formed, while preventing heat treatment from having a large effect on A36 steel. A36 steel usually also contains small amounts of other alloying elements, including manganese, sulfur, phosphorus, and silicon. The addition of these alloying elements gives A36 steel the desired chemical and mechanical properties. Since A36 does not contain significant amounts of nickel or chromium, it does not have excellent corrosion resistance.

Mechanical properties of A36 steel

The ultimate tensile strength of A36 steel is 58,000 to 79,800 psi. A36 is relatively ductile and can be stretched to about 20% of its original length in a tensile test. Its ductility and strength also give it good impact strength at room temperature.

Application fields of A36 steel plate

A36 steel is widely used in many different industries due to its relatively low cost. Also, as mentioned, its mechanical properties make it particularly suitable for structural applications. Many bridges are constructed with A36 steel. Likewise, buildings are usually constructed of A36 steel because of its strength and toughness. A36 steel is also used in components in the automotive, construction, heavy equipment and oil and gas industries.
