What are the effects of several main elements in steel on steel properties

2022-11-08 21:22:56   
Influence of several main elements in steel on its properties
 
•Carbon(c):With the increase of carbon content,the yield point and tensile strength increase,but the plasticity and impact properties decrease.Too high carbon content is likely to lead to disqualification of intergranular corrosion.The boundary between steel and iron is controlled by C content:
 
2.11%is steel•silicon(Si):
 
Si is a deoxidizer and desulfurizer with high strength and hardness,which can improve the hot workability of steel.
 
•Chromium(Cr):Chromium can significantly improve the strength,hardness and wear resistance of steel,but at the same time it can reduce plasticity and toughness.
 
•Nickel(Ni):Nickel can improve the strength of steel and keep good plasticity and toughness.Influence of several main elements in steel on its properties
 
•Molybdenum(Mo):adding molybdenum into steel can improve the mechanical properties of steel.
 
•Titanium(Ti):Titanium is a deoxidizer in steel.Reduce effectiveness sensitivity and cold brittleness.Adding a certain amount of titanium in steel has the ability to resist intergranular corrosion.
 
•Phosphorus(P):phosphorus is a harmful element in steel,which increases the cold brittleness of steel,worsens the welding performance,reduces the plasticity,and worsens the cold bending performance.In general,the lower the phosphorus content in steel,the better.
 
•Sulfur(S):sulfur is a harmful element in steel,which can cause thermal brittleness of steel,reduce ductility and toughness of steel,easily cause cracks during forging,and also reduce corrosion resistance of steel.Therefore,the sulfur content must be controlled as low as possible.
 
•Nitrogen(N):Nitrogen can improve the strength,low-temperature toughness and weldability of steel.Increase effectiveness sensitivity.Proper nitrogen can improve the pitting corrosion resistance and strength of stainless steel.
