Seamless steel pipe is a steel pipe that is perforated from a whole round steel and has no welds on the surface. According to the production method, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, extruded seamless steel pipes, and pipe jacking. According to the cross-sectional shape, the seamless steel pipe is divided into two types: round and special-shaped. The maximum diameter is 900mm and the minimum diameter is 4mm. According to different uses, there are thick-walled seamless steel pipes and thin-walled seamless steel pipes.

We choose a kind of steel pipe due to its practical function. No matter seamless steel pipe or welded one, its features would finally determine its work environment. Today, we would like to discuss about the elements increasing hardness of abrasion resistant steel pipe. What makes abrasion resistant steel more immune to wear than other types of steel? And how we guarantee its quality when used in tubes? The chemical composition of abrasion resistant steel would give us answers. Some alloys would increase the ability of abrasion resistance. For example, carbon will help block dislocations, thus, it will enhance the hardness and strength of a steel pipe. The added carbon also allows the steel to form microstructures with increased hardness when heated and quenched. There are other elements that can be added to abrasion resistant steel to increase its hardness value too. Chromium and manganese are also added to abrasion resistant steels to help reduce the negative effects caused by wear.

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.
Derived from the efficient recycling process our steel scrap undergoes rigorous processing to meet exacting specifications, guaranteeing consistency and reliability for diverse industrial applications.
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.
