During the last century the steel industry was influenced by several crises which invoked strong innovation activities in development of new classes of steels. innovation was based on the statement of representative of automotive industry bernhard rolinson who said: “Steel has a long tradition but despite of this its potential from the point of view of material properties is exploited only to 20%” [1]. importance of the steel as a material results from the following factors [2]: earth’s crust contains approximately 5,6% of iron, which ensures base material for its production, in comparison to other materials, the steel can be produced with lower energetic requirements, various steel classes can be produced effectively under constant level of quality, required properties of products made of steel can be reliable ensured by the technique of steel alloying and further processing (precise production), processing of steel made products (forming, welding, machining) is without any problems.
