  2. Carbon steel - Wikipedia

    en.wikipedia.org/wiki/Carbon_steel

    Carbon steel is a steel with carbon content from about 0.05 up to 2.1 percent by weight. The definition of carbon steel from the American Iron and Steel Institute (AISI) states:

  3. List of steel producers - Wikipedia

    en.wikipedia.org/wiki/List_of_steel_producers

    Top steel producing companies. This is a list of the largest steel-producing companies in the world mostly based on the list by the World Steel Association.The list ranks steelmakers by volume of steel production in millions of tons over time and includes all steelmakers with production over 10 million in 2021.

  4. Steel - Wikipedia

    en.wikipedia.org/wiki/Steel

    It is a fairly soft metal that can dissolve only a small concentration of carbon, no more than 0.005% at 0 °C (32 °F) and 0.021 wt% at 723 °C (1,333 °F). The inclusion of carbon in alpha iron is called ferrite. At 910 °C, pure iron transforms into a face-centred cubic (FCC) structure, called gamma iron or γ-iron. The inclusion of carbon ...

  5. Metal - Wikipedia

    en.wikipedia.org/wiki/Metal

    A refractory metal is a metal that is very resistant to heat and wear. Which metals belong to this category varies; the most common definition includes niobium, molybdenum, tantalum, tungsten, and rhenium as well as their alloys. They all have melting points above 2000 °C, and a high hardness at room temperature. Several compounds such as ...

  6. High-strength low-alloy steel - Wikipedia

    en.wikipedia.org/wiki/High-strength_low-alloy_steel

    High-strength low-alloy steel (HSLA) is a type of alloy steel that provides better mechanical properties or greater resistance to corrosion than carbon steel.HSLA steels vary from other steels in that they are not made to meet a specific chemical composition but rather specific mechanical properties.

  7. Structural steel - Wikipedia

    en.wikipedia.org/wiki/Structural_steel

    Metal deck and open web steel joist receiving spray fireproofing plaster, made of polystyrene-leavened gypsum. Steel loses strength when heated sufficiently. The critical temperature of a steel member is the temperature at which it cannot safely support its load [citation needed]. Building codes and structural engineering standard practice ...

  8. Reactivity series - Wikipedia

    en.wikipedia.org/wiki/Reactivity_series

    The most reactive metals, such as sodium, will react with cold water to produce hydrogen and the metal hydroxide: 2 Na (s) + 2 H 2 O (l) →2 NaOH (aq) + H 2 (g) Metals in the middle of the reactivity series, such as iron , will react with acids such as sulfuric acid (but not water at normal temperatures) to give hydrogen and a metal salt ...
