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.
Stainless steel is an iron alloy with a chromium content of at least 10.5%. Chromium forms a thin oxide layer on the surface of steel, known as the passivation layer.
This can prevent further surface corrosion. Increasing the chromium content can improve corrosion resistance.
Stainless steel also contains varying amounts of carbon, silicon, and manganese.
Other elements such as nickel and molybdenum can be added to impart other useful properties, such as enhanced forming ability and increased corrosion resistance.
Waste stainless steel refers to stainless steel waste generated from industrial manufacturing and stainless steel processes, as well as stainless steel equipment that has been damaged or scrapped due to long-term use, and stainless steel utensils used in daily life. Our factory produces approximately 20 tons of stainless steel per day, and we have abundant inventory of stainless steel waste with guaranteed quality. Scrap stainless steel is a high-grade alloy steel with a higher value than ordinary scrap steel.

Stainless Steel Strip
The properties of stainless steel are corrosion resistance, high ductility, attractive appearance and low maintenance.
Stainless steel contains chromium which provides the properties of corrosion resistance at high temperatures. Stainless steel can withstand corrosive or chemical environments due to its smooth surface. Stainless steel products are safe for long-term use with excellent resistance of corrosion fatigue.

430 Stainless Steel Strip Introductions
430 stainless steel strip is a general purpose stainless steel with good corrosion resistance.
It has better thermal conductivity than austenite grade stainless steel strip, a smaller thermal expansion coefficient than austenite strip, heat fatigue resistance.
Due to addition of stabilizing element titanium, it has good mechanical properties of welding.
Because of its chromium content, it is also called 18/0 or 18-0. Compared with 18/8 and 18/10, it contains slightly less chromium, and the hardness is correspondingly lower.
430 Stainless Steel Strip Applications
430 stainless steel strip is widely used for building decoration, fuel heating parts, hot water supply systems, household appliances, banding systems, home appliance parts and hareware.
430 Stainless Steel Strip Chemical Composition
The chemical components of grade 430 stainless steel strip is summarized in the following table:
Grade Standard C Si Mn P S Cr Ni Mo
