Webb1 nov. 2014 · Around 20 – 25 % of all W produced is used in these steels. Tungsten bearing addition agents Earlier W alloyed steels were manufactured by the addition of more or less pure W powder to the liquid steel, or, alternatively, by addition of an iron rich W pre-alloy, which was obtained from purified W ore. WebbTungsten is a naturally occurring element that exists in the form of minerals, but typically not as a pure metal (ATSDR 2005). The color of tungsten may range from white for the pure metal to steel - gray for the metal with impurities (NIOSH 2016). There are more than 20 known tungsten-bearing minerals (ATSDR 2005).
