Basic Introduction Of Steel For Forging

- Oct 18, 2018-

Forging steel is basically the addition of trace amounts of vanadium, CB and (or) titanium carbon-manganese steel.

The addition of trace alloys creates carbide or carbon nitride with a strong influence on the final properties of the steel. Forging steel, in terms of its cross-sectional shape, the most used is the round bar, followed by square steel; in terms of its production method, the most used is the rolling material, followed by the forging material. A brief introduction of its commodity knowledge is now available.

First, the steel according to the next method of processing different classification 1. Classification of steel, people are accustomed to according to their chemical composition, cross-sectional shape or use classification. The method of manufacturing steel for forging is characterized in that it contains c0.10-0.35%, si0.15-2.00%, mn0.40-2.00%, s0.03-0.10%, al0.0005-0.05%, ti0.003-0.05%, n0.0020-0.0070%, v0.30-0.70%, then contains a specific CR, Mo, Nb, PB and CA of one or more than two kinds of steel in the hot forging, and then cooled, so that the phase change after the end of the metal tissue 80% is ferrite 10 bainite tissue, and then in 200- 700 ℃ temperature for the aging treatment. According to the present invention can be produced with sufficient fatigue strength, machinability and yield strength of the hot forging steel.
