An alloy composition of nickel and copper is called Monel 400 tube, which at high temperatures is resistant to caustic solutions and seawater. It contains 66.5% Nickel, 31% Copper, 2.5% iron, 2% Manganese, 0.3% Carbon, 0.5% Silica, 0.024% Sulphur. It is known for its excellent strength, the only material resistant to acids and alkalis.
It is highly ductile and has good conductivity properties. In cold working environments, it can be easily hardened. It delivers excellent corrosion resistance properties for temperatures ranging from sub-zero to 1000° F.
Although both provide resistance to corrosion, there is huge difference between Inconel 600 and Monel 400, starting from their chemical composition.

Because it resembles same properties with Nickel-copper, alloy 400 tube material is expensive than other stainless steel. As a result, these types of products are recommended for use than the ones which are cheaper to withstand critical conditions such as high temperature, corrosive environments, and high strength requirements.
Another reason of this material to be expensive is because of the higher contents of copper in the range of 28-40% and minimum 63% Nickel, which are best known for exhibiting excellent properties in critical conditions. They also contain Iron, Manganese, Silica, Carbon in small amounts.

Although Monel 400 tubing comes with unique and excellent characteristics, there are some disadvantages of this material which we need to look upon. Due to the presence of higher contents of Nickel and Copper, it is expensive than any other alloy or stainless steel.
In other words, cost efficiency is the prime disadvantages. Although stainless steels cannot withstand extreme conditions and offer significant cost, they cannot withstand unique and critical conditions. But with this material, we can expect longevity, durability and high strength.
Monel 400 seamless tube comes with the size range of 4-219 mm, thickness ranging between 0.5-20mm, and length types of single, double random and cut length.
Distinctive difference emerge when comparing Monel 400 and Monel 500, based on the specific industrial and manufacturer’s demands.
A material well equipped with high corrosion resistance properties, which can only be hardened by cold working environments is the nickel 400 superheater tubes. It has excellent strength and shows toughness over a large range of temperatures.
Although both are composed of Nickel-Copper alloy composition, more advantageous for Monel 500, on the other hand, is its hardness and strength. This is achieved by adding Aluminium and Titanium. Adding to this, Monel 500 contains less impure elements than 2.4360 Monel 400 heat exchanger tube.
Because Monel 500 comprises less Sulphur content (<0.1%), they have better tensile strength and durability. As a result, this material is a must to be applicable for industries that require materials which are hard and have excellent strength.
