Why Scrap Metal Recyclers Should Know the Steels That They SellBlog | August 15th, 2017
Steel is the ideal metal to recycle since each tonne of scrap steel saves 633 kg of coal, 54 kg of limestone and 1131 kg of iron ore in the process of manufacturing new steel products. As a result, there is a large demand for scrap steel, but not all steel is suitable for the same purpose. Metal recyclers must know their steels, so that they can sort them correctly to sell the steels to those who will re-purpose the scrap into useful items once again.
Examples of Steel Items That Metal Recyclers Buy From You
The following are examples of major sources for scrap steel that you can sell to or buy from metal recyclers:
• Automobiles contain approximately 60-percent steel along with iron and other types of metals, including the precious metals of rhodium, palladium and platinum that are in catalytic converters.
• Appliances are typically comprised of approximately 65-percent steel along with copper, zinc and aluminium.
• Food cans are often referred to as metal, aluminium or tin cans and are typically made from tin-coated steel. They also can contain a small amount of nickel or chromium.
Information about Steels
Steels come in many forms. While some are uncoated, others receive a coating of zinc during the galvanizing process to ensure that they stand up to the weather elements outdoors without a risk of corrosion. Stainless steel is a general term that covers a variety of steels. What makes it different is the fact that it is made in a two-step process that includes the addition of carbon and iron along with chromium, nickel and other alloying elements. The process increases its resistant to corrosion.
The Re-Purposing of Different Grades of Stainless Steel
While metal recyclers need to be able to identify all their steels properly, stainless steel poses a unique issue since its various grades are utilised for specific purposes, such as the following list:
• 17-4 grade of stainless is in many elements of the aerospace and food industries.
• 304 stainless is ideal for kitchen equipment
• 316 grade of stainless steel is utilised by the marine and food industries.
• 310 grade of stainless is found in numerous types of high-temperature equipment since it can hold up under the heat.
• 321 grade of stainless steel often is in exhaust systems and aircraft bodies and interiors.
