  2. 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.

  3. List of materials properties - Wikipedia

    en.wikipedia.org/wiki/List_of_materials_properties

    A material property is an intensive property of a material, i.e., a physical property or chemical property that does not depend on the amount of the material. These quantitative properties may be used as a metric by which the benefits of one material versus another can be compared, thereby aiding in materials selection.

  4. SAE steel grades - Wikipedia

    en.wikipedia.org/wiki/SAE_steel_grades

    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.

  5. Alloy steel - Wikipedia

    en.wikipedia.org/wiki/Alloy_steel

    The simplest steels are iron (Fe) alloyed with carbon (C) (about 0.1% to 1%, depending on type) and nothing else (excepting negligible traces via slight impurities); these are called carbon steels. However, the term "alloy steel" is the standard term referring to steels with other alloying elements added deliberately in addition to the carbon.

  6. Stainless steel - Wikipedia

    en.wikipedia.org/wiki/Stainless_steel

    The average carbon footprint of stainless steel (all grades, all countries) is estimated to be 2.90 kg of CO 2 per kg of stainless steel produced, [95] of which 1.92 kg are emissions from raw materials (Cr, Ni, Mo); 0.54 kg from electricity and steam, and 0.44 kg are direct emissions (i.e., by the stainless steel plant). Note that stainless ...

  7. Spring steel - Wikipedia

    en.wikipedia.org/wiki/Spring_steel

    Spring steel is a name given to a wide range of steels [1] used in the manufacture of different products, including swords, saw blades, springs and many more. These steels are generally low-alloy manganese, medium-carbon steel or high-carbon steel with a very high yield strength. This allows objects made of spring steel to return to their ...

  8. Kevlar - Wikipedia

    en.wikipedia.org/wiki/Kevlar

    Kevlar (para-aramid) [ 2] is a strong, heat-resistant synthetic fiber, related to other aramids such as Nomex and Technora. Developed by Stephanie Kwolek at DuPont in 1965, [ 3][ 2][ 4] the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires.

  9. Ultimate tensile strength - Wikipedia

    en.wikipedia.org/wiki/Ultimate_tensile_strength

    Ultimate tensile strength (also called UTS, tensile strength, TS, ultimate strength or in notation) [ 1] is the maximum stress that a material can withstand while being stretched or pulled before breaking. In brittle materials, the ultimate tensile strength is close to the yield point, whereas in ductile materials, the ultimate tensile strength ...
