Inconel 601 alloy is a nickel-chromium-iron-based solid solution strengthened alloy. It has good high temperature corrosion and oxidation resistance, excellent cold and hot processing and welding properties, and has satisfactory thermal strength and high plasticity below 700°C. The alloy can be strengthened by cold working, and it can also be connected by resistance welding, melt welding or brazing. It is suitable for making anti-oxidation parts that can withstand low loads below 1100°C.

The performance characteristics of Inconel 601 are better than 600. It is an alloy with high chromium content. It has excellent oxidation and corrosion resistance. Because the composition also contains aluminum, it has good oxidation resistance and curing performance. The characteristics of this alloy are Excellent oxidation resistance and carbonization resistance at high temperature, good mechanical properties at room temperature and high temperature, good stress corrosion cracking resistance, high creep due to controlled carbon content and grain size Breaking strength.

Inconel 601 has different brand names in different countries, national standard brand numbers: NS3103, NS313, 0Cr23Ni63fe14al, American standard brand numbers: inconel601, No6601, German brand number: 2.4851, NICR23FE.

Inconel 601 processing and welding performance: 

It has good thermal processing performance, the deformation temperature is 870~1230 degrees, the large deformation is 1040~1230, and the low plastic temperature is 650~871 degrees. Cold working in solid solution is a good effect. The strengthening effect is not as good as 18CR18NI. The heat treatment is between 1100 and 1150 degrees, which is easy to weld, but different parts use different processes and materials.

Inconel 601 corrosion resistance: 

An important property of the alloy is its oxidation resistance at temperatures up to 1180°C. Even under severe conditions, such as heating and cooling cycles, a dense oxide film can be formed to obtain high resistance to peeling. Has good carbonization resistance. Due to the high content of chromium and aluminum, it has good oxidation resistance in high-temperature sulfur-containing atmospheres.

Inconel 601 application fields: 

mainly used in heating equipment, chemical industry, environmental pollution control, and power industry. Such as heat treatment equipment and parts, various industrial furnace tubes, sleeves, flame nozzles, electric heating elements, resistance wire sleeves, condenser tubes for the chemical industry, equipment parts in HNO3 production, and heat-resistant and corrosion-resistant parts for the glass industry.
