21-08-2020· Ironmaking, the first step in making steel, involves the raw inputs of iron ore, coke, and lime being melted in a blast furnace. The resulting molten iron—also referred to as hot metal—still contains 4-4.5% carbon and other impurities that make it brittle.
01-08-2011· Stainless steel One of the most used steels in items is stainless steel. Steel having 10% to 20% chromium makes steel stain free. There are three types of stainless steels namely austenitic, martensitic and Ferritic. Major applications of stainless steel are kitchen utensils, surgical items, dental equipment etc. Tool steel
Steelmaking Overview. Steelmaking is the second step in producing steel from iron ore. In this stage, impurities such as sulfur, phosphorus, and excess carbon are removed from the raw iron, and alloying elements such as manganese, nickel, chromium, and vanadium are added to produce the exact steel …
And, stainless steel is 100 percent recyclable and the process of recycling the steel is environmentally friendly. b) Cobalt Steel Cobalt is very temperature stable element and hence making cobalt steel highly ideal for steel pieces that will be subjected to extreme heat or friction.

Silicon Ore Processing Stainless Steel. Jun 21 2016nbsp018332Steel making is the method of processing and producing steel from iron ore and scrap It focuses on removing the slugs and other unwanted materials like phosphorus sulphur silicon nitrogen and excess carbon from the raw iron The next step targets on alloying it by adding various elements like manganese chromium nickel and …
While iron ore is the source of around 70% of the metallic raw material inputs to steelmaking globally, the rest is supplied in the form of recycled steel scrap. Steel production from scrap requires around one-eighth of the energy of that produced from iron ore – mainly in the form of electricity, rather than coal for production from iron ore.
