ASTM A36 steel plate is the most widely used hot-rolled steel product. As a kind of carbon structural steel product, its relative products are round rod steel, angle bar, and steel sections such as I-Beams, H-beams, angles, and channels. Hot rolled ASTM A36 has rough surface on the final product, it’s easy for further processing like machining.
ASTM A36 steel can be manufactured into various structural steel parts, it is vastly used in many different industries for a variety of applications, why choose ASTM A36? It provide good mechanical property and cost less. For example, it is also used in many bridge construction. Buildings are frequently constructed with A36 steel because of its high strength and toughness. Further more, ASTM A36 steel is also used in fields of automotive, construction, heavy equipment, and oil and gas industries.

Chemical Composition analyze
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.

Physical Property Analyze
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.
