1.Chemical composition of 18-8 stainless steel

18-8 stainless steel, also known as 304 stainless steel, is a common stainless steel alloy whose chemical composition is critical to its performance. 18-8 stainless steel is mainly composed of chromium (about 18%) and nickel (about 8%), and a small amount of elements such as carbon, silicon and manganese. The following is a detailed description of the main components of 18-8 stainless steel, with particular emphasis on the role of chromium and nickel in providing corrosion resistance:

Chromium (Cr): about 18% of the composition.

 

  • Chromium is one of the most critical elements in 18-8 stainless steel, so this model is named after it.The main function of chromium is to form a layer of chromium oxide film (Cr2O3) on the surface of stainless steel.
  • This thin and dense chromium oxide film is the basis of stainless steel’s corrosion resistance, effectively isolating the direct contact between stainless steel and the external environment.
  • This chromium oxide film is also self-healing and can regenerate even when scratched or worn, continuing to protect the stainless steel from further corrosion.

Nickel (Ni): About 8% of the composition.

 

  • Although the content of nickel in 18-8 stainless steel is small, its synergy with chromium further enhances the corrosion resistance.
  • Nickel helps maintain the integrity of the chromium oxide film, which increases the corrosion resistance of stainless steel.
  • In addition, nickel also improves the oxidation resistance of 18-8 stainless steel, enabling it to maintain structural stability in high temperature environments.

Other ingredients:

 
  • A small amount of carbon (C): usually below 0.08%. It provides enough hardness, but not enough to cause easy rusting.
  • Small amounts of silicon (Si) and manganese (Mn): These elements are used to fine-tune the physical properties of stainless steel, such as strength and machinability, but they are present in low amounts and do not affect its corrosion properties.

Overall, the chemical composition of 18-8 stainless steel has been carefully designed, where the synergistic effect of chromium and nickel is the key to providing its excellent corrosion resistance. This makes 18-8 stainless steel an ideal material for long-term performance in a variety of applications, especially in the face of harsh conditions such as humidity, chemicals and high temperatures. The presence of chromium and nickel makes 18-8 stainless steel environmentally friendly and sustainable, helping to extend service life and reduce resource waste and environmental impact.
