Seven of nickel (Ni): Ni can improve the strength of steel, while maintaining good ductility and toughness. Nickel acid have a higher corros

Chromium (Cr): the structural steel and tool steel, chromium can significantly improve the strength, hardness and wear resistance, but at the same

Sulfur (S): sulfur is usually harmful elements. Hot brittleness of the steel produced, reducing the ductility and toughness of the steel, causing c

phosphorus (P): In general, phosphorus is harmful elements in steel, increased cold brittleness of steel, welding performance deterioration, reduce

manganese (Mn): in steelmaking process, manganese is a good deoxidizer and desulfurizer, generally 0.30-0.50% manganese steel. In carbon steel adde

Silicon (Si): plus silicon as a reducing agent in the steel making process and deoxidizer, it killed steel containing 0.15-0.30% silicon. If the st
