HMS1 & HMS2
HMS1 (Heavy Melting Scrap 1) and HMS2 (Heavy Melting Scrap 2) are types of ferrous scrap, which are mainly composed of iron and steel. They are often sourced from dismantled machinery, buildings, and infrastructure, and are widely used in the production of new steel and iron products.
​
HMS1 is typically made up of clean, heavy scrap that is less than 1/4 inch thick, while HMS2 contains lighter scrap with a thickness greater than 1/4 inch. Both grades of scrap can be further classified into sub-categories based on their composition and quality.
​
Industries that commonly use HMS1 and HMS2 include steel mills, foundries, and metal recycling facilities. These materials are often melted down and used to produce new steel and iron products, including construction materials, automobiles, appliances, and packaging.
HMS1 is the higher quality grade of the two, consisting of clean, heavy scrap with a thickness of less than 1/4 inch. It is often used in the production of high-quality steel products and has a higher value than HMS2. HMS1 typically has a minimum thickness of 1/8 inch and is free of non-metallic materials such as rubber, plastic, and wood.
​
HMS2, on the other hand, contains lighter scrap with a thickness greater than 1/4 inch. It may also contain non-metallic materials such as rubber, plastic, and wood. HMS2 is often used in the production of lower-quality steel products and has a lower value than HMS1.
Both grades of scrap have similar physical properties, including high density, which makes them heavy and difficult to transport. They also have high tensile strength and can withstand significant pressure and stress without breaking.
​
In terms of chemical properties, both HMS1 and HMS2 are composed mainly of iron and steel, with varying amounts of other elements such as carbon, manganese, and silicon. The exact composition of the scrap can vary depending on the source and the manufacturing process that produced it.
