High-tensile steels are low-carbon, or steels at the lower end of the medium-carbon range, which have additional alloying ingredients in order to increase their strength, wear properties or specifically tensile strength. These alloying components consist of chromium, manganese, silicon, molybdenum, nickel and vanadium. High Strength Steel Plate is good, strong, long-lasting steel, but it isn't as light as its more high-tech, the steel known as chromoly. A workhorse of the industry, chromoly is a light in weight and strong steel. High tensile plate within equations, is the maximum stress that a material can withstand while being stretched or pulled before breaking. In ductile materials the ultimate tensile strength can be higher, whereas in brittle materials the ultimate tensile strength is close to the yield point. It is also known for its atmospheric corrosion resistance, the degradation inflicted to materials through exposure to air-borne pollutants.
