HMS1 and HMS2 – What are These Types of Steel, and Why They Should Be Recycled?

Blog | October 24th, 2018

The heavy melting scrap of used steel and wrought iron fall into two main categories of HMS1 and HMS2 for sorting, recycling, selling and processing purposes. Scrap of this nature comes from dismantled or demolished structures or items and should never be disposed of in landfills since it can be reprocessed into new, usable products. Today, recyclers will buy this scrap to help keep it from just being thrown away where it can no longer be of use to anyone.

HMS1 and HMS2 Both Have Subcategories

The primary difference between HMS1 and HMS2 is the fact that the first one does not contain galvanised or blackened steel, whereas, the second one does include both of them. According to the Institute of Scrap Recycling Industries or the ISRI the subcategories of HMS1 and HMS2 are as follows:

  • ISRI 200 HMS1 includes steel and wrought iron scrap that is one-quarter inch or thicker. All the pieces of this need to be less than 60 inches by 24 inches.
  • ISRI 201 HMS1 is the same as ISRI 200 except the pieces need to be smaller than 60 inches by 18 inches.
  • ISRI 202 HMS1 only differs from ISRI 200 in that the pieces need to measure less that 60 inches by 18 inches.
  • ISRI 203 HMS2 includes wrought iron and steel scrap that is galvanised or black that has a thickness of one-eighth inch or more.
  • ISRI 204 HMS2 only differs from ISRI 203 in that the pieces cannot be larger than 36 inches by 18 inches.
  • ISRI 205 HMS2 is the same as ISRI 204 but can include thin-gauge automotive scrap.
  • ISRI 206 HMS2 is the same as ISRI 205 except that it cannot contain pieces larger than 60 inches and 18 inches.

Why You Should Always Recycle HMS1 and HMS2 Used Steel and Wrought Iron• Recycling HMS1 and HMS2 keeps these scrap metals out of landfills.• Reduces the quantity of raw ore necessary to manufacture new steel and wrought iron products.

  • Lessens the use of energy and water in manufacturing new wrought iron and steel products since there is not as much need to process raw ore.
  • Reduces CO2 emissions, which protects the environment.
  • You can make money by recycling HMS1 and HMS2 obsolete scraps of steel and wrought iron.
