Soft Annealing: Heat to 780-810°C, cool slowly. This will produce a maximum Brinell hardness of 240.
Stress Relieving: Stress relieving to remove machining stresses should be carried out by heating to 650°C, holding for one hour at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
Hardening: Harden from a temperature of 1080-1160°C followed by air, oil or warm bath quenching. Hardness after quenching is 47-53 HRC.

The Tire derived Steel or Tire Wire Scrap is a light melting scrap obtained during the shredding and granulation process of used tires. Generally 10% - 20% of the weight of an old passenger car tyre usually consists of steel. An average shredding plant produces about 100-200 MT of steel tyre wire and its quality can vary according to technology, storing and management systems adopted by the producing plants. We can provide tire wire scrap that still contains up to 20% rubber/fiber. This percentage is detected by manual separation test. The material can be loaded loose in 40 HC container. For further details, please feel free to contact us.
Supplier: Cast iron skulls, cast iron borings and turnings, steels skulls, eaf skulls, plate iron, mill scale, metal scrap, incinerated scrap (e46)
Electro galvanized wire BWG20 , wire diameter: 0.93-0.95 mm.
Waste Specification: European Classification: E46 EWC Code: 19.01.02 Basel Code: B10 10 The material is loose steel scrap processed through an incinerating plant for domestic waste followed by magnetic separation, fragmentized into pieces and consisting partly of tin coated steel cans. At a visual inspection, the material is fragmentized, with iron and steel parts, resulting partly cut or in shredded form. The stock appears heterogeneous and contains all kind of cut or dismantled steel parts such as sheets, bars, frames, wires, bolts and other iron/steel household residues. The incinerated scrap is eventually oxidized, due to the thermal and cooling treatments, that the material has been submitted to. The burnt scrap also contains minor slag parts, ash and iron oxide, due to the recovery process. Such components are inherent and adhere to the scrap surface. The total impurities, can be sorted, but not fully removed. The consignment does not contain any type of arms, ammunition, mines, shells, cartridges, radioactive contaminated, or any other explosive material in any form either used or otherwise. The collected stock, is stored in open air, on cemented flooring. Due to the scrap dimensions and the material conditions, this particular scrap, should be carefully evaluated first, by the end users, to confirm its adequate recovery ratio and its suitability to be re-melted in the electric arc furnace.
