Hastelloy is a nickel-chromium-molybdenum corrosion-resistant structural steel. It is a heat-treatable alloy with high strength, hardness and good wear resistance. Hastelloy is mainly used to manufacture various tools, cutting tools and mechanical parts.
Specific grades of Hastelloy, such as Hastelloy C276, Hastelloy B-2, etc., play an important role in different application scenarios. For example, Hastelloy C276 alloy is one of the only materials resistant to corrosion by moist chlorine, hypochlorite and chlorine dioxide solutions, and has significant resistance to high-concentration chloride solutions such as ferric chloride and copper chloride. Corrosion resistance.
Monel is an iron-based alloy mainly composed of manganese. Due to its low carbon content, it has high strength and low hardness. It has excellent wear resistance, fatigue strength and good corrosion resistance; good corrosion resistance in oxidizing media; poor corrosion resistance in reducing media; medium plasticity at high temperatures and high creep strength and Durable plasticity and other characteristics.
Differences between Hastelloy and Monel alloy:
1. Composition difference:
The chemical composition of Hastelloy C-276 stainless steel is C0.03%, Si0.015%, Mn0.10%, Cr1.50%, Ni1.20%, Mn: 0.05%, S≤0.002%, P≤0.025%;
The chemical composition of Monel N036 aluminum alloy is Al0.05%~0.5%, Si<0.01%, Fe<0.02%, Cu<0.01%, Ni<0.05%.
2. Difference in mechanical properties:
The tensile strength of Hastelloy c276 stainless steel is ≥520MPa/mm2, and the elongation is ≥30%;
The tensile strength of Monel N036 aluminum alloy is ≥490MPa/mm2, and the elongation is ≥40%;
