Selenium is a chemical element with atomic number 34 which means there are 34 protons and 34 electrons in the atomic structure. The chemical symbol for Cadmium is Cd. Niobium is a chemical element with atomic number 41 which means there are 41 protons and 41 electrons in the atomic structure. Iodine is the least abundant of the stable halogens, being the sixty-first most abundant element. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Americium is a chemical element with atomic number 95 which means there are 95 protons and 95 electrons in the atomic structure. It is even less abundant than the so-called rare earths. Nearly all technetium is produced synthetically, and only minute amounts are found in the Earth’s crust. Terbium is a silvery-white, rare earth metal that is malleable, ductile, and soft enough to be cut with a knife. TENSILE - YIELD STRENGTH OF STEEL CHART. The chemical symbol for Tellurium is Te. Adding a small amount of non-metallic carbon to iron trades its great ductility for the greater strength. Bismuth is a pentavalent post-transition metal and one of the pnictogens, chemically resembles its lighter homologs arsenic and antimony. Manganese is a metal with important industrial metal alloy uses, particularly in stainless steels. Nobelium is the tenth transuranic element and is the penultimate member of the actinide series. As the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine. It is also the most corrosion-resistant metal, even at temperatures as high as 2000 °C. (function ($) { Praseodymium is the third member of the lanthanide series and is traditionally considered to be one of the rare-earth metals. Yield Strength, Tensile Strength and Ductility Values for Steels at Room Temperature: Material: Yield Strength: Tensile Strength % Elong. The chemical symbol for Thorium is Th. A major development was the discovery that steel could be made highly resistant to corrosion and discoloration by adding metallic chromium to form stainless steel. Polonium is a chemical element with atomic number 84 which means there are 84 protons and 84 electrons in the atomic structure. Mercury is a heavy, silvery d-block element, mercury is the only metallic element that is liquid at standard conditions for temperature and pressure. The chemical symbol for Indium is In. Total elongation, which includes both elastic and plastic deformation, is the amount of uniaxial strain at fracture and is depicted as strain at point Z. These are fully quenched to martensite during processing. Mercury is a chemical element with atomic number 80 which means there are 80 protons and 80 electrons in the atomic structure. Yttrium is a chemical element with atomic number 39 which means there are 39 protons and 39 electrons in the atomic structure. The chemical symbol for Neodymium is Nd. Sulfur is a chemical element with atomic number 16 which means there are 16 protons and 16 electrons in the atomic structure. Beryllium is a hard, grayish metal naturally found in mineral rocks, coal, soil, and volcanic dust. Silicon is a hard and brittle crystalline solid with a blue-grey metallic lustre, it is a tetravalent metalloid and semiconductor. Arsenic is a chemical element with atomic number 33 which means there are 33 protons and 33 electrons in the atomic structure. elongation at break(%) = ez = 100*(lz-lo)/lo               Eq. The chemical symbol for Antimony is Sb. Reduction of area is calculated by measuring the cross sectional area at the fracture point (Az). Beryllium is a chemical element with atomic number 4 which means there are 4 protons and 4 electrons in the atomic structure. Ultimate tensile strength is often shortened to “tensile strength” or even to “the ultimate.” If this stress is applied and maintained, fracture will result. Chlorine is a yellow-green gas at room temperature. Arsenic is a metalloid. Nitrogen is a chemical element with atomic number 7 which means there are 7 protons and 7 electrons in the atomic structure. Martensitic steels are also high in C and Mn.
