Inconel 601 ( UNS N06601 ) nickel-based alloy Elastic modulus: 124.7-206.5GPa.

Incone1601 alloy is a nickel-chromium-iron based solid solution strengthened alloy, which has good high-temperature corrosion resistance and oxidation resistance, excellent hot and cold processing and welding performance, and has a total resistance below 700 “C.

UNS N06601 elbow has good heat resistance and high plasticity. The alloy can be strengthened by cold working, and can also be connected by resistance welding, soldering, or brazing. It is suitable for making oxidation resistance no low load below 1100C.

It has very good resistance to stress corrosion cracking Due to the control of carbon content and grain size, 601 has high creep rupture strength, so 601 is recommended for use in areas above 500 ¡ãC.

601 is widely used in Isolation tanks in ammonia reforming and catalytic support grids in nitric acid manufacturing, exhaust system components and combustion chamber of solid waste incinerator.

Generally, its corrosion resistance is very good in reducing environments, but poor in oxidizing conditions.

The alloy has been used in a variety of applications. It has excellent resistance to rapidly flowing brackish water or seawater. It is particularly resistant to hydrochloric and hydrofluoric acids when they are de-aerated.

It is not useful in oxidizing acids, such as nitric acid and nitrous.

The alloy is slightly magnetic at room temperature. Monel 400 is widely used in the chemical, oil and marine industries.

It is resistant to most alkalis, salts, waters, food products, organic substances and atmospheric conditions at normal and elevated temperatures.

This nickel alloy is attacked in sulfur-bearing gases above approximately 700¡ã F and molten sulfur attacks the alloy at temperatures over approximately 500¡ã F.

This alloy is more resistant to nickel under reducing conditions and more resistant than copper under oxidizing conditions, it does show however better resistance to reducing media than oxidizing.

It has good mechanical properties from subzero temperatures up to about 480C.

Alloy 400 is resistance to neutral, alkaline and acid salts is shown, but poor resistance is found with oxidizing acid salts such as ferric chloride.

Monel 400 has excellent resistance to chloride ion stress corrosion cracking.

Monel 400 is widely used in Feed water and steam generator tubing.

Monel 400 is widely used in Brine heaters, sea water scrubbers in tanker inert gas systems.

Alloy 400 is virtually immune to chloride ion stress corrosion cracking in typical environments.

Monel 400 is a Nickel-Copper alloy, resistant to sea water and steam at high temperatures as well as to salt and caustic solutions.

Monel 400 is a nickel-copper alloy with excellent corrosion resistance in a wide variety of media. Monel 400 is characterized by good general corrosion resistance, good weldability and moderate to high strength.

It¡¯s also ideal for sensitive industries such as food preparation and pharmaceuticals, as the risk of contamination is much lower.

316L has a lower proportion of carbon in its composition.

To qualify as 316L stainless steel, the amount of carbon cannot exceed 0.03%. This decreases the risk of carbon precipitation, making it a better option for welding to ensure maximum corrosion resistance.

316L is the superior choice for high corrosion and high temperature applications. Since 316L contains less carbon than 316, it has better intergranular corrosion resistance, meaning its welds won¡¯t decay, unlike with 316 stainless steel.

Although 316L contains less carbon, 316 and 316L stainless steels cost approximately the same.

316L steel is more susceptible to gaining some degree of magnetism.

316L is popular for pharmaceutical and photography equipment because it can withstand welding and corrosive chemicals.

Grade 316L, the low carbon version of 316 and is immune from sensitization (grain boundary carbide precipitation).

It is extensively used in heavy gauge welded components (over about 6mm). There is commonly no appreciable price difference between 316 and 316L stainless steel.

The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperatures.
