Comparison of Nickel 600 and EN 1.4501 Stainless Steel
Comparison of Nickel 600 and EN 1.4501 Stainless Steel
Nickel 600 is a nickel-chromium-iron alloy, while EN 1.4501 is a super duplex stainless steel. The main difference lies in the base metal and alloying elements, resulting in drastically different properties: Nickel 600 performs well in high-temperature applications and has good resistance to certain chemicals, such as dry chlorine. In contrast, EN 1.4501 is a high-strength steel with excellent resistance to chloride corrosion, such as pitting and stress corrosion cracking.
Is Inconel 600 better than SS 304?
Stainless steel 304 is a versatile and cost-effective general-purpose material, while Inconel 600 performs exceptionally well under extreme conditions. Understanding the properties and applications of these materials will help you choose the right alloy for your needs.
Nickel 600 (Alloy 600)
Composition: Nickel-chromium-iron alloy, containing approximately 72% nickel, 14-17% chromium, and 6-10% iron.
Key Advantages:
High Temperature Resistance: Usable from low temperatures up to 2000°F (1093°C).
Corrosion Resistance: Resistant to a wide range of corrosive chemicals, especially alkaline solutions, and exhibits excellent resistance to dry chlorine and hydrogen chloride gases at temperatures up to 650°C.
Mechanical Properties: Good machinability, weldability, and high strength, but strength decreases significantly at high temperatures.
EN 1.4501 Stainless Steel
Composition: A super duplex stainless steel with iron as the balancing element. Key alloying elements include high chromium (24-26%), significant amounts of molybdenum (3-4%) and nickel (6-8%), as well as copper and tungsten.
Key Advantages:
Corrosion Resistance: Excellent resistance to pitting and crevice corrosion in chloride-containing environments (such as seawater).
Mechanical strength: High strength, exceeding that of many austenitic and duplex stainless steels.
Other properties: Excellent ductility and impact strength at both room temperature and sub-zero temperatures, as well as high wear resistance and erosion resistance.
High pitting corrosion equivalent value (PREN): >40, indicating its superior resistance to pitting corrosion.
