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 breaks up the categories further: [1]

Low-background steel, also known as pre-war steel [1] and pre-atomic steel, [2] is any steel produced prior to the detonation of the first nuclear bombs in the 1940s and 1950s. Typically sourced from ships (either as part of regular scrapping or shipwrecks ) and other steel artifacts of this era, it is often used for modern particle detectors ...

The original Ducol, or "D"-steel, is a manganese-silicon steel, a toughened version of the new, proven standard construction steels developed by David Colville & Sons just after WW1. [ a ] It was an improvement on British Admiralty "HT" (High Tensile) steel, a shipbuilding and light armour steel developed c1900 and used through the end of WWI.
Compared to iron, steel allowed for greater structural strength for a lower weight. France was the first country to manufacture steel in large quantities [citation needed], using the Siemens process. At that time, steel plates still had some defects, and the outer bottom plating of the ship was made of wrought iron.
An example of a HMIS III label for Diesel fuel..

As a result, by 1910 no navy had any ...
