  3. Steel grades - Wikipedia

    en.wikipedia.org/wiki/Steel_grades

    EN 10027-1 steel grade designation system. European standard steel grade names fall into two categories: [1] Steel specified by purpose of use and mechanical properties. Steel specified by chemical composition. The inclusion of a letter 'G' before the code indicates the steel is specified in the form of a casting.

  4. SAE steel grades - Wikipedia

    en.wikipedia.org/wiki/SAE_steel_grades

    The SAE steel grades system is a standard alloy numbering system (SAE J1086 – Numbering Metals and Alloys) for steel grades maintained by SAE International. In the 1930s and 1940s, the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels. These efforts were similar ...

    The Bielefelder Kennhuhn was developed in the 1970s in the area of Bielefeld, in Ostwestfalen-Lippe in the state of Nordrhein-Westfalen. [4] It was created by Gerd Roth by cross-breeding of birds of Malines and Welsumer stock with American Barred Rock birds.

  6. Low-background steel - Wikipedia

    en.wikipedia.org/wiki/Low-background_steel

    Low-background steel, also known as pre-war steel [1] and pre-atomic steel, [2] is any steel produced prior to the detonation of the first nuclear bombs in the 1940s and 1950s. Typically sourced from ships (either as part of regular scrapping or shipwrecks ) and other steel artifacts of this era, it is often used for modern particle detectors ...

  7. Steelmaking - Wikipedia

    en.wikipedia.org/wiki/Steelmaking

    Steel is made from iron and carbon. Cast iron is a hard, brittle material that is difficult to work, whereas steel is malleable, relatively easily formed and versatile. On its own, iron is not strong, but a low concentration of carbon – less than 1 percent, depending on the kind of steel – gives steel strength and other important properties.

  8. Structural steel - Wikipedia

    en.wikipedia.org/wiki/Structural_steel

    Steel never turns into a liquid below this temperature. Pure Iron ('Steel' with 0% Carbon) starts to melt at 1,492 °C (2,718 °F), and is completely liquid upon reaching 1,539 °C (2,802 °F). Steel with 2.1% Carbon by weight begins melting at 1,130 °C (2,070 °F), and is completely molten upon reaching 1,315 °C (2,399 °F).

    300 series stainless steels are the larger subgroup. The most common austenitic stainless steel and most common of all stainless steel is Type 304, also known as 18/8 or A2. Type 304 is extensively used in such items as cookware, cutlery, and kitchen equipment. Type 316, also known as A4, is the next most common austenitic stainless steel.
