We are glad to propose 500 MT of stain less steel mill scale.
Mill scale is formed on the outer surfaces during by the hot rolling lamination of stainless-steel products.
At a visual inspection the material is a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in colour, but it also contains considerable alloying elements such as chromium and nickel.
The recovery ratio after melting in furnace for the most valuable alloy elements is:
- Ni: 3.5 - 4.5%
- Cr: 6-8%
From the chemical and physical analysis performed on the scrap, and according to the European environmental rules, the material has been classified as a special non dangerous waste, listed in green list. In particular the mill scale can be classified as follows:
Waste code: 10 02 10
The material is stored on cemented flooring, and it can be loaded loose in tipper trucks or containers.
Chemical analysis of the material is available on request.

Natural Red Iron Oxide is the most widely occurring Minerals in Earth. It is widely used in many applications due as it is economical as compared to Synthetic Oxides.
Applications :
Red Oxide is anti-corrosive and has inertness to alkali and chemicals which makes its very viable for making of paint, protective coating for steels, cement coloring, NPK Fertilizers, paving tiles.
Clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker is ground to a fine powder and used as the binder in many cement products.
