Material Selection for Temporary Strainer: Comparison of The Reuse Rates of C95800 Nickel Aluminum Bronze And Duplex Stainless Steel S31803

I. CHEMICAL COMPOSITION AND MICROSTRUCTURE
C95800 NICKEL ALUMINUM BRONZE IS A COPPER-BASED ALLOY, AND ITS MAIN COMPONENTS INCLUDE COPPER, NICKEL, ALUMINUM, IRON, AND MANGANESE, ETC. In its chemical composition, the content of copper is relatively high, usually around 81.5%, the nickel content is around 4%, and the aluminum content is around 9%. The microstructure of this alloy mainly consists of α phase and β phase. The α phase has good toughness and strength, while the β phase endows the material with high hardness and wear resistance.

DUPLEX STAINLESS STEEL S31803 IS AN AUSTENITE-FERRITE DUPLEX STAINLESS STEEL. Its chemical composition mainly includes elements such as chromium, nickel, molybdenum, and nitrogen. The chromium content is relatively high, usually around 22%, the nickel content is around 5%, and the molybdenum content is around 3%. The microstructure of this alloy consists of austenite phase and ferrite phase, and the ratio of the two phases is approximately 50:50. This duplex structure gives it excellent corrosion resistance and high strength.

II. MECHANICAL PROPERTIES
C95800 nickel aluminum bronze has a relatively high tensile strength, usually above 585 MPa, a yield strength above 240 MPa, and an elongation after fracture above 15%. This material has good wear resistance and anti-fatigue performance, and is suitable for working conditions with high loads and high wear.

Duplex stainless steel S31803 also has a relatively high tensile strength, usually around 515 MPa, and a yield strength around 450 MPa. Its hardness is relatively low, but it has good toughness and impact resistance. This material performs excellently in terms of high strength and high toughness, and is suitable for working conditions that need to withstand relatively large stresses.

III. CORROSION RESISTANCE
C95800 nickel aluminum bronze has excellent corrosion resistance to seawater, and can resist corrosive factors in seawater such as chloride ions and microorganisms. In addition, it also has good resistance to sulfate corrosion and cavitation corrosion. The corrosion resistance of this material is comparable to that of super stainless steel, and it is especially suitable for fields such as seawater desalination and shipbuilding.

DUPLEX STAINLESS STEEL S31803 HAS GOOD RESISTANCE TO PITTING CORROSION AND CREVICE CORROSION, AND PERFORMS PARTICULARLY WELL IN MEDIA CONTAINING CHLORIDE IONS. Its corrosion resistance is better than that of traditional austenitic stainless steel, and it can effectively resist the erosion of chloride ions. This material is suitable for fields such as chemical engineering, petroleum, and offshore engineering.

IV. REUSE RATES
C95800 Nickel Aluminum Bronze
The reuse rate of C95800 nickel aluminum bronze is relatively high, mainly due to its excellent wear resistance and anti-fatigue performance. In the application of strainer, this material can withstand frequent cleaning and replacement operations, and is not prone to deformation or damage. In addition, its good corrosion resistance also enables it to maintain good performance after long-term use. Generally speaking, the service life of C95800 nickel aluminum bronze strainer can reach several years or even longer.

Duplex Stainless Steel S31803
The reuse rate of duplex stainless steel S31803 is also relatively high, mainly due to its good toughness and impact resistance. In the application of strainer, this material can withstand relatively large pressures and impacts, and is not prone to cracks or fractures. In addition, its excellent corrosion resistance also makes it perform well in complex working conditions. Generally speaking, the service life of duplex stainless steel S31803 strainer is also relatively long and can meet the needs of industrial production.

V. APPLICATION SCENARIOS AND COST ANALYSIS
C95800 Nickel Aluminum Bronze
C95800 nickel aluminum bronze is widely used in fields such as seawater desalination, shipbuilding, and the nuclear industry. Its main advantage lies in its excellent corrosion resistance to seawater and its ability to effectively resist various corrosive factors in seawater. In addition, the price of this material is relatively low, and it has a high cost-performance ratio. In working conditions that require frequent cleaning and replacement of strainer, C95800 nickel aluminum bronze is an ideal choice.

Duplex Stainless Steel S31803
Duplex stainless steel S31803 is widely used in fields such as chemical engineering, petroleum, and offshore engineering. Its main advantage lies in its excellent resistance to pitting corrosion and crevice corrosion and its ability to effectively resist the erosion of chloride ions. In addition, this material has relatively high strength and toughness and can withstand relatively large stresses. However, the price of duplex stainless steel S31803 is relatively high, and the cost investment is relatively large.

VI. CONCLUSION

BOTH C95800 NICKEL ALUMINUM BRONZE AND DUPLEX STAINLESS STEEL S31803 ARE FILTER MATERIALS WITH EXCELLENT PERFORMANCE.They have their own characteristics in terms of chemical composition, mechanical properties, corrosion resistance, and reuse rates. C95800 nickel aluminum bronze has excellent wear resistance and anti-fatigue performance, outstanding corrosion resistance to seawater, and a relatively low price, and is suitable for fields such as seawater desalination and shipbuilding. Duplex stainless steel S31803 has good toughness and impact resistance, excellent resistance to pitting corrosion and crevice corrosion, and is suitable for fields such as chemical engineering, petroleum, and offshore engineering.

When selecting filter materials, enterprises should conduct comprehensive considerations based on specific working conditions, medium types, cost budgets, and other factors. If the working conditions mainly involve seawater or media containing chloride ions and require frequent cleaning and replacement of strainer, C95803 nickel aluminum bronze is a relatively ideal choice. If the working conditions have relatively high requirements for the strength and toughness of materials and need to withstand relatively large stresses, duplex stainless steel S31803 is more appropriate. Through reasonable selection of filter materials, enterprises can not only improve the service life and operation efficiency of equipment but also reduce maintenance costs, thus maximizing economic benefits.
