S31803 and S32760 are both duplex stainless steels, each with unique characteristics and application areas. Understanding these differences is crucial for selecting the appropriate material for specific applications. Below are the main differences between them:
Alloy composition:
S31803 typically contains
22% chromium, while S32760 contains a higher chromium content of approximately 25%.
S32760 is approximately twice as strong as S31803 due to its higher alloy content, particularly chromium, and has significantly higher corrosion resistance.
Although both have a dual-phase microstructure, a balance of austenite and ferrite grains, the high degree of alloying of S32760 may affect the specific proportions and properties of its microstructure.
Both S31803 and S32760 are widely used in applications requiring high strength and good corrosion resistance, such as chemical processing, marine engineering and pump manufacturing.
The S32760 may be more suitable for use in more demanding environments due to its higher performance.
Both materials may require special processing and welding techniques due to their high strength and dual-phase properties.
cost: S32760 may be more expensive than S31803 due to its higher alloy content.
The S32760 may maintain its performance over a wider temperature range, especially in high-temperature applications.
The choice of S31803 or S32760 often depends on specific application requirements, including required mechanical properties, corrosion resistance, processing cost and availability. For further detailed specifications and application guidance on these materials, it is recommended to contact the material supplier or a professional engineering consultant.
