alloyed scrap
Alloyed scrap is steel scrap that contains certain additives, so-called alloying elements, such as chromium, nickel, silicon, manganese or molybdenum. Their use is very diverse. They are often used in products or special machine parts that are subject to high stresses. Alloy steels can, for example, achieve high strength and high resistance to aggressive acids or other chemicals.
Where do alloyed scraps come from?
Alloyed scrap is produced in large quantities in the processing industry. Here they are used, for example, in the production of rollers for use in rolling mills. In addition, tool steels for the production of press molds or dies as well as steels in the machining industry for the production of high-speed steels (HSS) are made from alloyed steels. Alloyed scrap is also used in the aerospace and pipeline construction industries. Chromium steels and other stainless steels with chromium and nickel (V2A or V4A) are used where corrosion is a problem or where there is an environment with aggressive chemicals.
What is done with alloyed scrap?
At RHM, the alloyed scrap is first subjected to a professional incoming inspection. Here the main focus is on knowing the percentage of alloying elements in the scrap in question and whether the analyses match the respective qualities. The alloying elements are usually determined using X-ray fluorescence analysis (XRF) or optical emission spectrometry (OES). With this information, the scrap can then be sorted, stored and delivered according to the customer’s specifications. If necessary, this also includes shredding these secondary raw materials before they are returned to the economic cycle. Different scraps, which differ analytically, can also be combined according to the customer’s specifications so that a steel with the desired characteristics is produced when the combined scraps are melted down. This is referred to as assembling a so-called blend.
What does the use of alloyed scrap mean for the environment?
The use of secondary raw materials instead of primary raw materials means a comprehensive reduction in environmental impact. For this reason, the processing and marketing of scrap makes a significant contribution to climate protection. The use of alloyed scrap not only saves a huge amount of CO2 and energy, but also conserves considerable amounts of natural resources. Scrap can be returned to the economic cycle an infinite number of times without changing its properties.
Why scrap from RHM?
RHM has a very broad and strong base. It markets ferrous scrap, foundry scrap, alloyed scrap, non-ferrous scrap and industrial residues / metallurgical residues. The portfolio also includes steel product trading. RHM supplies well-known steelworks and foundries as well as the chemical industry.
RHM is always open to new technical challenges in order to further develop and optimize the recycling of scrap. In addition to a high standard of quality, the company also attaches great importance to research and development (R&D) of innovations. RHM’s way of thinking is such that challenges are implemented quickly and “unbureaucratically” in order to meet sustainability and customer requirements in the best possible way.
