Apple juice is one of the most useful fruit juices. This drink is low calorie and contains a lot of iron, and therefore is indicated for the treatment of anemia and cardiovascular diseases. In addition to the iron in the Apple juice contains vitamin C, phosphorus, citric and malic acid, magnesium, potassium and some other trace elements.
Steel (from it. Stahl) is a deformable (ductile) alloy of iron with carbon (and other elements), characterized by eutectoid transformation. The carbon content in steel is not more than 2.14 percent, but not less than 0,022 %. The carbon makes the iron alloys strength and hardness, reducing the ductility and toughness.
