ASTM A36 steel is an American standard carbon structural plate, which implements the standard ASTM A36/A36M-03a. This standard applies to riveted, bolted and welded structures for bridges and buildings, as well as general-purpose structural steel quality carbon steel sections. Steel plates and bars.
A36 steel is a mild steel. The carbon content of mild steel is less than 0.3%, which makes A36 steel easy to machine, weld, and form, making it very suitable for general purpose steel. Low carbon also prevents heat treatment from affecting A36 steel.
A36 steel also contains small amounts of other alloying elements, such as manganese, sulfur, phosphorus, and silicon. Adding these alloying elements can make A36 steel have the required chemical and mechanical properties. Because A36 has too little nickel content and too little chromium content, its corrosion resistance is not very good.
The ultimate tensile strength of A36 steel is 58,000 psi to 79,800 psi. The exact ultimate tensile strength depends on a variety of factors, such as chemical composition and molding method.
A36 steel is relatively ductile and can stretch to about 20% of its original length when tested in tension. Its ductility and strength also give it excellent impact strength at room temperature.
A36 is manufactured in a similar way to most carbon steels.
First, iron ore and coal are mixed in a furnace. Impurities are removed and alloying elements are added to the molten steel, which eventually solidifies into a rectangular ingot.
A36 steel is generally hot rolled, which means that while the ingot is at high temperature, it can be formed to final size using rolls.
A36 steel is popular due to its relatively low cost. The A36 steel can be seen in many different industries and in a variety of applications. Also, as mentioned above, its mechanical properties make it particularly suitable for structural applications. Many bridges are constructed with A36 steel.
Likewise, A36 steel is often made into buildings due to its high strength and toughness. A36 steel is also used in components for the automotive, construction, heavy equipment and oil and gas industries.
