Tungsten steels

Tungsten steel is an alloy that acts somewhat like molybdenum to form important steel alloys tungsten steel is tough and hard, wears well, resists rusting, and will take a sharp cutting edge. 

Tungsten is recovered mostly from mineral scheebte and wolframite. The recovery process depends on the mineral, the cost, and the end use i.e., the commercial products to be made. Typical industrial processes have been developed to convert tungsten ores to tungsten metal and alloy products, tungsten steel, non-ferrous alloys, cast and cemented tungsten carbides, and tungsten compounds. A few processes are mentioned briefly below. 

The majority of the iron produced in the blast furnace is converted into different steel alloys (p. 166) such as manganese and tungsten steels as well as the well-known example of stainless steel (p. 166).

KTW bullet The original design had a hard steel or tungsten steel core with a copper gas check and the current version is a solid brass or bronze bullet without a gas check. Both have a gliding metal half jacket and the exposed portion of the bullet is coated with green-colored Teflon. 

In the analysis of tungsten steels the sample may be dissolved in hydrochloric acid or dilute sulphuric acid in absence of air. The tungsten remains undissolved and is ignited, fused with sodium carbonate, and estimated by ordinary methods. ...
