Over 80% of the world's ferrochrome is utilised in the production of stainless steel. In 2006, 28,000,000 tons of stainless steel were produced. Stainless steel depends on chromium for its appearance and resistance to corrosion. Average chrome content in stainless steel is approx. 18%. It is also used to add chromium to carbon steel.
04-05-2014· Krupp combined blowing-stainless (KCB-S) process -The production of stainless steels in the BOF converter using the top lance was being practiced prior to the advent of the AOD Process. After introduction of the AOD process, Krupp Stahl AG modified the converter so that combined blowing through the lance and tuyeres could be practiced for refining stainless steels.
The VOD (vacuum oxygen decarburization) process was developed by Witten (now Thyssen) in Germany between 1962 and 1967. Between 1959 and 1962, Witten had produced stainless steels in their LD converter (decarburization of pig iron, addition of low carbon ferrochrome, and …
How Steel Is Made. Steel is primarily produced using one of two methods: Blast Furnace or Electric Arc Furnace. The blast furnace is the first step in producing steel from iron oxides. The first blast furnaces appeared in the 14th century and produced one ton per day. Even though equipment is improved and higher production rates can be achieved ...
25-05-2017· Common grades of carbon steel for knife making include C1045, C1075, and C1090. Stainless Steel. Stainless steel is another type of knife-making metal. The added benefit of using stainless steel is addition of chromium and other alloying elements that increase corrosion resistance.

Making lye from wood ash. Lye made from wood ash is potassium hydroxide, not sodium hydroxide -- there's 10 times as much potassium as sodium in wood ash. The process makes lye water. If you boiled off all the water you could use it as the catalyst to make biodiesel, but you'd need more accurate pH measures than those listed below.
