A36 steel consists of 0.29 percent carbon, 0.9 percent manganese, 0.04 percent phosphorus, 0.05 percent sulfur, and 0.35 percent silicon, with iron comprising the remaining majority. Material Grades defines A36 steel as having an applicable thickness between 10 and 60 millimeters.
A36 steel is a structural application material with characteristics similar to Fe-510 steel. The material standard assessed by the American Society for Testing Materials for describing A36 steel is ASTM A36/A36M-08. A36 steel is a billet steel with characteristics and mechanical properties ideal for structural applications.
A36 steel exhibits a tensile strength between 400 and 550 newtons per millimeter. The yield strength of A36 steel is at least 250 newtons per millimeter. The steel exhibits a minimum percentage range for elongation of 23 percent. Both of these mechanical properties are significantly lower than Fe-510 steel.
Construction contractors commonly use A36 steel plate to produce pre-fabricated buildings, while other metalworkers prefer to use it for creating cabinets, enclosures and equipment housings. Pipe and tubing manufacturers also frequently use A36 steel for their products. A36 is ideal for many piping applications because it can be galvanized, increasing its resistance to corrosion. O'Neal Steel considers A36 easier to fabricate and machine than other types of steel.
