1.4418 is a stainless steel material, also known as x4crnimo16-5-1. The following will be a pair of 1The composition of 4418 material is analyzed.
1.Composition analysis.
1.The main components of 4418 material are as follows:
1) Chromium (CR): Chromium is one of the key elements in stainless steel, which is able to form a dense oxide layer, which gives stainless steel excellent corrosion resistance. 1.The chromium content in 4418 is as high as 150-17.0%, which provides good corrosion resistance.
2) Nickel (Ni): Nickel can improve the corrosion resistance, high temperature resistance and impact toughness of stainless steel. 1.The nickel content in 4418 material is 40-6.0%, so that it has good corrosion resistance and heat resistance.
3) Molybdenum (MO): Molybdenum helps to improve the corrosion resistance of stainless steel, especially in acidic environments. 1.The molybdenum content in 4418 material is 04-1.0%, which further improves its corrosion resistance.
4) Silicon (Si): Silicon is a reinforcing agent that can improve the strength and hardness of materials. 1.The silicon content in 4418 material does not exceed 10%。
5) Manganese (MN): Manganese has a strengthening effect in stainless steel, which can improve its strength and toughness. 1.The manganese content in 4418 material does not exceed 10%。
In addition, 1The 4418 material also contains trace elements such as phosphorus (P) and sulfur (S), and the phosphorus content does not exceed 0040%, sulfur content does not exceed 0015%。The presence of these trace elements can affect the processability and embrittlement tendency of the material.
1.4418 material is mainly composed of chromium, nickel, molybdenum and other components, with excellent corrosion resistance, heat resistance and strength, suitable for a variety of industrial applications.
