EN 1.1170 Steel vs Nickel 600
EN 1.1170 is a common carbon manganese steel (similar to AISI 1330), suitable for general engineering applications but with lower strength; while Inconel 600 is a high-performance nickel-chromium alloy with excellent corrosion resistance (especially against chlorides and caustic alkalis), high-temperature strength, and oxidation resistance, making it ideal for harsh chemical and thermal environments. This differs from the lower-priced steel, which is more suitable for simpler structural applications. The key difference lies in the balance between performance and cost: Inconel 600 can withstand extreme conditions that 1.1170 steel cannot.
What is the difference between Nickel 600 and Nickel 625?
Nickel 600 does not contain molybdenum, while Nickel 625 contains more than 8% molybdenum, which gives it a certain degree of resistance to reduction. Nickel 600 does not possess this property. Therefore, Nickel 625 has significantly better overall corrosion resistance.
EN 1.1170 steel, also known as 30Mn5 alloy structural steel, is a high-strength alloy structural steel with good toughness and wear resistance. Its main components include carbon (0.26%~0.34%), silicon (≤0.40%), and manganese (0.70%~1.10%), and trace amounts of sulfur, phosphorus, chromium, nickel, etc. This material is widely used in the automotive and machinery manufacturing industries, and is suitable for manufacturing high-strength carburized parts, such as small-section fasteners, frame longitudinal beams, and gearbox gears.
Nickel 600 (also known as Inconel 600) is a nickel-chromium based solid solution strengthened heat-resistant alloy with an austenitic structure, possessing excellent high-temperature strength, corrosion resistance, and oxidation resistance. Although often classified as "stainless steel," it is strictly speaking a nickel-based alloy (nickel content ≥72%), significantly different from traditional chromium-nickel stainless steels (such as 304). 2. Chemical Composition (ASTM B168 Standard) (1) Overall Corrosion Resistance Acidic Media: Resistant to dilute hydrochloric acid, sulfuric acid, and phosphoric acid (non-oxidizing acids), but performance deteriorates in concentrated hydrochloric acid or high-temperature sulfuric acid. Alkaline Media: Excellent resistance to caustic alkalis (such as NaOH), especially in high-temperature molten alkalis. Chloride Environments: Better resistance to pitting and crevice corrosion than 304 stainless steel, but not as good as molybdenum-containing Inconel 625.
