  2. Mangalloy - Wikipedia

    en.wikipedia.org/wiki/Mangalloy

    Mangalloy is a unique non-magnetic steel with extreme anti-wear properties. The material is very resistant to abrasion and will achieve up to three times its surface hardness during conditions of impact, without any increase in brittleness which is usually associated with hardness. [ 2 ] This allows mangalloy to retain its toughness.

  3. Manganese - Wikipedia

    en.wikipedia.org/wiki/Manganese

    Manganese is a chemical element; it has symbol Mn and atomic number 25. It is a hard, brittle, silvery metal, often found in minerals in combination with iron. Manganese was first isolated in the 1770s. It is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels.

  4. Ferromanganese - Wikipedia

    en.wikipedia.org/wiki/Ferromanganese

    Ferromanganese. Ferromanganese metal, note mirror-like sheen responsible for German name spiegel. Ferromanganese is an alloy of iron and manganese, with other elements such as silicon, carbon, sulfur, nitrogen and phosphorus. [ 1 ] The primary use of ferromanganese is as a type of processed manganese source to add to different types of steel ...

    en.wikipedia.org/wiki/Josiah_Marshall_Heath

    Josiah Marshall Heath (8 November 1790 – 28 January 1851) [1] was an English metallurgist, businessman and naturalist, who invented the use of manganese to deoxidise steel. [2] In India he learned the local steel-making processes, including wootz, but having failed to found a profitable steel mill there he returned to England and settled in ...

    Corinthian bronze (gold, silver) Cunife (nickel, iron) Cupronickel (nickel) CuSil (silver) Cymbal alloys (tin) Devarda's alloy (aluminium, zinc) Hepatizon (gold, silver) Manganin (manganese, nickel) Melchior (nickel); high corrosion resistance, used in marine applications in condenser tubes.

  7. Manganite - Wikipedia

    en.wikipedia.org/wiki/Manganite

    Manganite is a mineral composed of manganese oxide-hydroxide, MnO(OH), crystallizing in the monoclinic system (pseudo-orthorhombic). [3] Crystals of manganite are prismatic and deeply striated parallel to their length; they are often grouped together in bundles. The color is dark steel-grey to iron-black, and the luster brilliant and ...

  8. 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.

  9. 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 ...
