Inconel Round Bar
Inconel is an alloy of nickel chromium and iron, resistant to corrosion at high temperature. When Inconel is heated, it forms a thick layer protecting the surface from further attack. Inconel’s high temperature strength is developed by solid solution strengthening or precipitation hardening, depending on the alloy.
- Inconel 600 – solid solution strengthened.
- Inconel 601 – good oxidation resistance at high temperature and resistance to chloride-ion stress-co corrosion.
- Inconel 617 – an exceptional combination of metallurgical stability, strength and oxidation resistance.
- Inconel 625 – acid resistant, good weldability.
- Inconel 718 – it strengthens good weldability.
- Inconel 722 – age-harden able by heat treatment.
- Inconel 725 – a nickel-chromium-molybdenum-niobium alloy that is highly resistant to corrosion and has extremely high strength.
- Inconel 750 – precipitation-harden able, corrosion and oxidation resistance, high strength at high temperature.
- AL-6XN – low carbon, high purity, nitrogen-bearing “super-austenitic” stainless alloy. The alloy was designed to be a seawater resistant material and has since been demonstrated to be resistant to a broad range of very corrosive environments.
- Inconel 800 – has excellent tensile strength and resistance to oxidation as well as carburization properties.
- Inconel 825 – great resistance too many corrosive environments such as pitting, crevice corrosion and stress-corrosion cracking.
- Inconel 925 – a precipitation-harden able nickel-iron-chromium alloy with additions of molybdenum and copper.
- Inconel 945 – an age harden able nickel-iron-chromium alloy with addictions of molybdenum, copper, niobium, titanium and aluminium.
Inconel is a family of austenitic nickel-chromium-based super alloys. These alloys are resistant to both oxidation and corrosion. When heated, it forms a thick, stable layer that protects the surface from corrosion. Inconel retains its strength over a wide range temperatures, whereas other materials like aluminium or steel, would succumb to creep.
Inconel have several drawbacks. Welding them can be difficult because of potential cracking. Few alloys have been developed to overcome this problem. Machining and shaping nickel alloys can be difficult due to rapid work hardening.
