A36 steel can have ultimate tensile strengths from 58,000 to 79,800 psi. The exact ultimate tensile strength is determined by a variety of factors such as chemical composition and forming method. A36 is relatively ductile and can elongate to around 20% of its original length when tensile testing. Its ductility and strength also give it excellent impact strength at room temperature.
