The Stainless Steel Recycling Life Cycle

The Stainless Steel Recycling Life Cycle is a continuous process that helps to conserve natural resources, reduce energy consumption and minimise waste.

Grades of Stainless Steel

Stainless steel grades are typically categorised based on their chemical composition, with different grades containing varying amounts of elements such as chromium, nickel, and molybdenum.

Specialised Sorting

Specialised sorting is critical in the stainless steel recycling industry because stainless steel contains a mix of different metals, including iron, chromium, nickel, and other alloying elements.

Testing and Analysis

Testing and analysing equipment is used to determine the chemical composition of the stainless steel scrap metal, this assists in identifying the grade of stainless steel scrap metal received.

Interesting Facts about Stainless Steel

  • Stainless steel was invented in Sheffield, England in 1913 by Harry Brearley. He was trying to develop a corrosion-resistant steel for gun barrels and stumbled upon a steel that was highly resistant to rust and staining.
  • Stainless steel is not actually stainless – it can still corrode and stain under certain conditions. However, its resistance to corrosion and staining is much greater than that of regular steel.
  • Stainless steel is 100% recyclable, and recycling it requires only a fraction of the energy required to produce new steel. This makes it an environmentally-friendly material choice.
  • The Statue of Liberty in New York City is also made of stainless steel. The statue’s exterior is made up of 300 separate copper plates, each of which is supported by a stainless steel framework.
  • Stainless steel is used extensively in the construction of modern skyscrapers. Its high strength, low weight and corrosion resistance make it an ideal material for building facades, structural beams and other components.
  • Stainless steel is used in the production of surgical instruments and implants. Its biocompatibility, corrosion resistance and strength make it an ideal material for medical applications.
  • The world’s largest stainless steel sculpture is the “Bean” in Chicago’s Millennium Park. The sculpture, officially known as “Cloud Gate” is 33 feet tall, 66 feet long, and weighs 110 tons.
