65Mn CK67 high carbon cold rolled spring steel strip
Hardened and Tempered Steel Strip
Hardened and Tempered is a thermal process that strengthens steel strips through a controlled heating and cooling process. The hardening process involves heating the steel strip to above the rapidly cooling. The steel strip in this condition is extremely brittle and requires further treatment in the tempering. Then strips are reheated to a lower temperature and holding it at the given temperature for a given period of time. This process is done in an inert atmosphere to avoid oxidation. This type of steel strip has big degree of toughness and has excellent spring properties

Galvanized GI Steel Rolls & Plates & Coils
Whatâ??s the difference between galvanized GI steel coils and plates?
I. Definition
Galvanized GI Steel coil and galvanized sheet are galvanized steel. The galvanized coil is a continuous hot dip galvanized coil in the production process. While galvanized sheet is a single hot dip galvanized sheet in the production process.
2. the production process
The production process of galvanized coil and galvanized sheet is different.
The production process of galvanized coil generally includes multiple processes such as coil heating, hot dip galvanizing and shearing into coil.
The galvanized sheet is generally the zinc alloy coating through the hot dip technology directly coated to the surface of the steel plate.
So the production process is relatively simple, the process difficulty is relatively low.
3. material thickness
The material thickness of galvanized coil and galvanized sheet is also slightly different.
Generally speaking, the thickness of galvanized coil is relatively thin. We mainly use it for the production of cold rolled, coating and other thin steel products.
The thickness of galvanized sheet is relatively thick. We mainly use it in the manufacture of glass fiber reinforced plastic, automotive panels, roof panels and other steel products requiring strength and corrosion resistance.
4. Advantages and Disadvantages
Both galvanized coil and galvanized sheet have their own advantages and disadvantages.
The production cycle of galvanized coil is short, the process is simple, and it is suitable for the production of low thickness and high precision steel products.
The galvanized sheet has the advantage of hardness, corrosion resistance, wear resistance and other multiple properties.
However, the production process of galvanized sheet is time-consuming and laborious, and the production cost is relatively high.
5. Application fields
The application areas of galvanized coil and galvanized sheet are also different.
Galvanized coil is usually used in the production of home appliances, building materials, auto parts, pipes and other high-demand steel products.
The galvanized sheet is mainly used in automobile manufacturing, construction engineering, petroleum, chemical and other industries.
In addition, because of the good corrosion resistance of galvanized sheet, it is also widely used in Marine engineering, railway, bridge and other fields.

Mill scale, is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling hot iron or steel billets in rolling or steel mills.
It looks like a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in color.
Being produced during the reheating, conditioning and hot rolling operation for the production of steel articles, the mill scale initially adheres to the steel surface and protects it from atmospheric corrosion, provided no break occurs in this coating.
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:
Einecs (european commission no.): 266-007-8
Waste code: 10 02 10
Basel code: b 12 30
Hs code: 2619.00
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.
