ASTM A36 steel

ASTM A36 Carbon Structural Steel Plate

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.
 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.

ASTM A36 Hot Rolled Steel Plate	Chemical Compostion
	Element	content
	Carbon, C	0.25 - 0.290 %
	Copper, Cu	0.20 %
	Iron, Fe	98.0 %
	Manganese, Mn	1.03 %
	Phosphorous, P	0.040 %
	Silicon, Si	0.280 %
	Sulfur, S	0.050 %

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.
