What elements does mold steel contain?
Mold steel is a special steel used to make molds. It has the characteristics of high NMness, high wear resistance and high heat resistance. The composition of mold steel bar mainly includes carbon, silicon, manganese, phosphorus, sulfur, chromium, molybdenum and other elements.
Carbon (C) is the main element in hot die steel, which can improve the NMness and wear resistance of the steel, giving the mold good wear resistance and cutting performance.
Silicon (Si) can increase the strength and NMness of mold steel, while also improving the steel's wear resistance and high temperature resistance.
Manganese (Mn) is mainly used to increase the NMness and strength of mold steel, while also improving the impact resistance of the steel.
Phosphorus (P) and sulfur (S) are impurity elements in mold steel. Excessive phosphorus and sulfur content will have an adverse effect on the performance of the steel, easily cause cold brittleness, and reduce the plasticity of the steel. Therefore, during the production process Phosphorus and sulfur levels need to be controlled.
Chromium (Cr) is an important alloying element in hot forging die steel. It can significantly improve the NMness, wear resistance and corrosion resistance of the steel, giving the mold high wear resistance and corrosion resistance.
Molybdenum (Mo) is a reinforcing element of mold steel round bar, which can significantly improve the strength and NMness of steel, while also improving the wear resistance and heat resistance of steel.
In addition to the above main elements, metal mold steel also contains small amounts of other alloying elements, such as titanium (Ti), nickel (Ni), vanadium (V), etc., which can further improve the performance of mold steel through alloying.
These elements in mold steel are mixed and processed in a certain ratio. Through appropriate heat treatment and processing technology, mold alloy steel can have higher NMness, wear resistance, high temperature resistance and corrosion resistance, thus It can meet the requirements of the mold during the working process.
