Steel mixed with the element Manganese to give a very hard, strong steel alloy. Most likely used for machinery.

Annealed steel binding wire is commonly used for tying and securing steel reinforcement bars. It is typically made from low-carbon steel and is soft, flexible, and easy to twist, making it suitable for construction and reinforcement work.
both of these are same In some places they are used interchangeabl low carbon steel has 0.05-0.15% carbon mild carbon steel has0.16-0.29% carbon http://www.metalsupplies.com/

Steel is an alloy, not a purified metal; but sometimes the excess of phosphorous, sulfur, carbon etc. in the melt need to be deleted.
Phosphorous.
red phosphorous
sulphur and phosphorous
Steel is an iron alloy. When the alloy contains chromium and phosphorous it doesnot rust. Other metals may be added for improved strength and heat resistance.
pig iron, wrought iron and cast iron. These are broad classifications used commercially, they can be subclassified. Chemically we say that its pure or impure, contains sulphur/phosphorous/impurities(slag, etc.)/carbon in so and so % range
It used to be sulfur or phosphorous in World War 2.
yes
Phosphorus is used in making fertilizers, and explosives.
This element is phosphorous.
