Steel with Cr.Mo.Cr-Mo steel chemical elements make a difference to Cr.Mo.Cr-Mo steel'ear resistance and toughness,Bebon International offer Detailed information to you Cr.Mo.Cr-Mo steel chemical elements Carbon(C),Silicon(Si),Manganese(Mn),Phosphorus(P).

Carbon (C): increase in carbon content in steel, elevated yield point and tensile strength, ductility and impact resistance decreased when the carbon content of 0.23% over the deterioration of the weldability of steel, for welding low-alloy structural steel, carbon content less than 0.20%. High carbon content also reduces the steel atmospheric corrosion resistance, high carbon steel in the open-air stockyard easily corroded; In addition, carbon steel cold brittleness and aging sensitivity can increase.

Silicon (Si): plus silicon as a reducing agent and a deoxidizer in the steelmaking process, so killed steel containing 0.15 to 0.30% silicon. If the silicon content of the steel exceeds 0.50-0.60%, even if the silicon alloying elements. Silicon can significantly improve the elastic limit of the steel, the yield point and tensile strength, it is widely used as a spring steel. Adding 1.0-1.2% of Si, the strength can be increased by 15-20% in the quenched and tempered structural steel. The combination of silicon and molybdenum, tungsten, chromium, improve corrosion resistance and oxidation, can produce heat-resistant steel. Silicon-containing 1-4% of low-carbon steel, with a high permeability for electrical industrial silicon steel. The increase in the amount of silicon, will reduce the weldability of steel.

Manganese (Mn): in the steelmaking process, manganese is good deoxidizer and desulfurizer ships steel, manganese 0.30-0.50%. Add more than 0.70% carbon steel, even when the manganese steel, compared to general steel steel not only a sufficient toughness and high strength and hardness, to improve the hardenability of steel to improve the hot workability of the steel, 16Mn steel is 40% higher than A3 yield point. 11-14% of manganese steel with high wear resistance for excavator bucket, ball mill liner. Manganese content increased, to weaken steel corrosion resistance, reduce welding performance.

Phosphorus (P): In the general case, phosphorus is a harmful element in the steel to increase cold brittleness of the steel, so that the deterioration of the welding performance, reduce the plasticity, so that the cold bending performance deterioration. Usually require steel phosphorus content of less than 0.045%, high-quality steel requires some lower.
