Inconel 625 is a corrosion and oxidation resistant nickel alloy that is used both for its high strength and outstanding aqueous corrosion resistance. Its outstanding strength and toughness is due to the addition of niobium which acts with the molybdenum to stiffen the alloy’s matrix. Alloy 625 has excellent fatigue strength and stress-corrosion cracking resistance to chloride ions. This nickel alloy has excellent weldability and is frequently used to weld AL-6XN. This alloy resists a wide range of severely corrosive environments and is especially resistant to pitting and crevice corrosion.
Inconel 600 alloy is a nickel-chromium-iron-based solid solution strengthened alloy. It has good high temperature corrosion resistance and oxidation resistance, excellent cold and hot processing and welding properties, and has satisfactory thermal strength and high plasticity below 700°C.
Inconel 718 is a nickel-based super alloy that is well suited for applications requiring high strength in temperature ranges from cryogenic up to 1400°F. Inconel 718 also exhibits excellent tensile and impact strength. Inconel 718 alloy is a precipitation hardening nickel-chromium-iron alloy containing niobium and molybdenum. It has high strength, good toughness and corrosion resistance in high and low temperature environments below 650°C. Its state can be solid solution treatment or precipitation hardening state.
Inconel 725 alloy is a nickel-chromium-molybdenum-niobium alloy. It has excellent corrosion resistance. After aging heat treatment, it can greatly increase the strength of the alloy and greatly improve the ductility and tensile properties of the alloy. The alloy also has strong resistance to stress corrosion. Used for pipe fittings, joints and bearings in acid-resistant equipment. It is also widely used in marine marine equipment
