Heavy Melting Steel
Heavy melting steel (HMS) or heavy melting scrap is a designation for recyclable steel and wrought iron. It is broken up into two major categories: HMS 1 and HMS 2, where HMS 1 does not contain galvanized and blackened steel, whereas HMS 2 does. The Institute of Scrap Recycling Industries The Institute of Scrap Recycling Industries (ISRI) is a United States-based private, non-profit trade association representing more than 1,300 private and public for-profit companies – ranging from small, family-owned businesses to multi-nationa ... breaks up the categories further: * ISRI 200 (HMS 1): Wrought iron or steel scrap and larger in thickness. All pieces must be smaller than * ISRI 201 (HMS 1): Same as ISRI 200 except pieces must be smaller than . * ISRI 202 (HMS 1): Same as ISRI 200 except pieces must be smaller than . * ISRI 203 (HMS 2): Wrought iron or steel scrap, black and galvanized, and larger in thickness. * ISRI 204 (HMS 2): Same as ISRI 203 except pieces must be smaller t ...

Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carbon, other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wrought Iron
Wrought iron is an iron alloy with a very low carbon content (less than 0.08%) in contrast to that of cast iron (2.1% to 4%). It is a semi-fused mass of iron with fibrous slag Inclusion (mineral), inclusions (up to 2% by weight), which give it a wood-like "grain" that is visible when it is etched, rusted, or bent to structural failure, failure. Wrought iron is tough, malleable, ductile, corrosion resistant, and easily forge welding, forge welded, but is more difficult to welding, weld electrically. Before the development of effective methods of steelmaking and the availability of large quantities of steel, wrought iron was the most common form of malleable iron. It was given the name ''wrought'' because it was hammered, rolled, or otherwise worked while hot enough to expel molten slag. The modern functional equivalent of wrought iron is Carbon steel#Mild or low-carbon steel, mild steel, also called low-carbon steel. Neither wrought iron nor mild steel contain enough carbon to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Institute Of Scrap Recycling Industries
The Institute of Scrap Recycling Industries (ISRI) is a United States-based private, non-profit trade association representing more than 1,300 private and public for-profit companies – ranging from small, family-owned businesses to multi-national corporations—operating at more than 6,000 facilities in the United States and 40 countries worldwide. Its membership is made up of manufacturers and processors, brokers and industrial consumers of scrap commodities, including ferrous and nonferrous metals, paper, electronics, rubber, plastics, glass and textiles. ISRI's associate members include equipment and service providers to the scrap recycling industry. Manufacturers and sellers of equipment and services—such as shredders, balers, cranes, cargo transporters, computer systems and more—also promote the scrap recycling industry through their membership in ISRI. ISRI advocates for safety and responsibility in many different areas of the scrap recycling industry – metals theft, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
