Stainless steel is defined today as a steel alloy containing at least 10% chromium, plus other elements – especially nickel. The chromium forms an oxide film on the material which makes it corrosion resistant.
The residue is free (unAlloyed) iron on the surface. Free iron should not be confused with Alloyed iron which is a major component of the stainless steel, or with ferrite which is a specific type of crystalline structure and a normal component of stainless steel, especially cast stainless steel. Sources of .
The current utilization rate of steel slag is only 22% in china, far behind the developed countries. At present, the amount of slag deposited in storage yard adds up to 30Mt, leading to the occupation of farm land and serious pollution to the environment.
Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly contains oxides of calcium, silicon, magnesium, and aluminium. Any sandy component or quartz component of the original ore automatically carries through the smelting process as silicon dioxide.

Oct 01, 2000· Stainless Steel. What''s in stainless steel? Stainless steel is composed of iron, carbon, chromium, nickel, manganese, silica, and many other metals in smaller quantities. The amount of each of these components depends upon the grade of stainless steel. Generally, the higher the chromium content, the more corrosion resistant the metal is.
Steel slag is a byproduct of the steelmaking and steel refining processes. This paper provides an overview of the different types of steel slag that are generated from basicoxygenfurnace (BOF) steelmaking, electricarcfurnace (EAF) steelmaking, and ladlefurnace steel refining processes. The mineralogical and morphological properties of BOF and electricarcfurnaceladle [EAF(L)] slag ...
