S45110 stainless steel is a high-strength, high-corrosion resistant stainless steel material, which is widely used in petroleum, chemical, pharmaceutical and other fields. Its chemical composition and mechanical properties are of great significance to ensure the quality and reliability of products. This article will introduce the chemical composition tolerance range and hardness of S45110 stainless steel in detail.
1. Tolerance range of chemical composition.
The chemical composition of S45110 stainless steel is one of the key factors in its performance. According to the standard, the chemical composition tolerance range of S45110 stainless steel is as follows:
Carbon(c): 0030%
Silicon (Si): 075%
Manganese (mn): 200%
Phosphorus (p): 0035%
Sulfur (s): 0030%
Chromium (cr): 1800-21.00%
Nickel (Ni): 900-12.00%
Molybdenum (Mo): 075%
Nitrogen (n): 010%
Titanium(Ti): 020%
Aluminium (AL): 075%
The content of these components directly affects the mechanical properties and corrosion resistance of S45110 stainless steel. For example, too high levels of carbon and nitrogen can lead to excessive strength and hardness of the material, but less corrosion resistance;The chromium and nickel content directly affects the corrosion resistance of the material. Therefore, in the production process, the content of these components must be strictly controlled to ensure the performance and quality of S45110 stainless steel.
2. Hardness. Hardness is one of the important mechanical properties of S45110 stainless steel, which reflects the material's ability to resist deformation and failure. According to the standard, the hardness range of S45110 stainless steel is as follows:
Rockwell hardness (HRC): 28
Vickers hardness (HV): 310
Brinell hardness (hb): 265
These hardness requirements ensure that S45110 stainless steel can maintain excellent mechanical properties and corrosion resistance under various working conditions. In practical applications, the choice of hardness should be determined according to the specific conditions and requirements of use. For example, a higher hardness can be selected for applications that need to withstand high loads or wear resistance;For occasions that need to withstand greater stress and impact, a lower hardness should be chosen.
In conclusion, the chemical composition tolerance range and hardness of S45110 stainless steel are key factors in its performance and quality. During production and use, these parameters must be strictly controlled to ensure the reliability and safety of the product. At the same time, understanding and mastering these parameters is also the key to the correct selection of S45110 stainless steel materials.
