it is soft when cold but hard when heated up.
Dead soft steel typically contains primarily iron with trace amounts of carbon and other alloying elements such as manganese, phosphorus, sulfur, and silicon. The exact composition can vary depending on the specific grade of dead soft steel.
Low carbon steel, is very soft, and can be easily shaped, but high carbon steel is extreamly stong and is used for springs or high strenght wire

It's done by annealing - just heat the steel red hot and allow it to cool on its own.
Low carbon steel is steel with low carbon. High carbon steel is steel with high carbon
The Nike Pro Combo OS are made of forged carbon steel. Nike Speed Step Steel constant-weight shafts are made from soft, forged 1030 carbon steel that gives an excellent feel transmission. This high strength steel alloy creates a shaft that is 30% lighter than traditional steel shafts. The lightweight and soft-tip shafts provide for higher ball flight and greater distances.
Heat treating of high carbon steel to harden it is an instantaneous process. The steel is heated red hot, causing the formation of crystals of very hard type of Iron Carbide called "Martinsite". If cooled slowly, the Martensite reverts to iron and carbon again and the steel remains soft. But if cooled rapidly by plunging the red hot steel in water or oil, there is insufficient time for the Martinsite to break down to iron and carbon, and it remains as crystals of very hard Martinsite, imparting hardness to the steel.
Low carbon steel has about 0.05% to 0.25% carbon content that is combined with iron. When compared with steel with higher carbon content, its properties are that it is relatively softer, less strong, more malleable, easy to shape, and has a higher melting point. Generally speaking the strength and hardness of steel increases with the percentage of carbon in the alloy.
There are 4 they are Low Carbon steel, Medium Carbon Steel, High Carbon Steel and Eutectiod
Pure iron is too soft for many uses. Different metals are added in order to strengthen the steel and make it harder.
