Alloy 400 Round Bar

Monel 400 Bar (UNS N04400) and alloy 400 round bar

Equipped with unique properties, Monel 400 round bar is best for highly severe marine and acidic environments requiring great resistance and high strength.

Monel 400

Monel 400 (UNS N04400), a nickel-copper alloy and alloy 400 round bar, is best in high strength and corrosion resistance. It is extensively used in a wide variety of severely acidic and alkaline environments. Monel alloys are also used for pipings.

Monel alloys exhibit great resistance to steam and seawater. Equipped with high tolerance and excellent weldability, monel can be often used in marine applications like manufacturing pump shafts and seawater valves. Its great seawater resistance makes it good for trolling wire.

Monel is particularly resistant to hydrofluoric and hydrochloric acids when de-aerated. It can be slightly magnetic at room temperature. Monel alloys are more resistant than nickel under reducing conditions as well as to copper during oxidizing copper. Monel alloys exhibit better resistance than other alloys to reducing media than oxidizing. It also shows resistance to alkaline, neutral, and acidic salts; however, it has poor resistance to oxidizing acid salts like ferric chloride.

Monel 400 bars (ASTM B164 QQ-N-281 Din 17750) feature thermal conductivity and good ductility which makes them fitting for heavy-duty construction materials. They provide exceptional quality and can also withstand across high levels of pressure and a high amount of weight. Another feature is that monel bars also exhibit possess superior mechanical properties even at sub-zero temperatures.

Monel 400 bars, with their highly strong, unique properties make it a staple of numerous applications especially in the large areas: chemical and marine.

These bars can also be applied in other applications such as:

  • Boiler feeds

  • Heat exchangers

  • Pickling bat heating coils

  • Pumps and valves for chlorinated, perchloroethylene plastics

  • Propeller and pump shafts

  • Transfer piping

  • Steam generator tubing and feed water

  • Hydrofluoric acid alkylation and sulfuric acid plants

  • Cladding for oil refinery crude columns

  • Reboiling tube

  • Sea water scrubbers and brine heaters

Benefits of Using Monel 400 Bar

Monel 400 bar is a nickel-copper-iron alloy that has a hardness of 300HB. It is used in the production of a range of products, including springs, gears, bearings, and linings. There is a Monel 400 round bar that is used in the manufacture of springs and has high corrosion resistance.

It is one of the most popular types of bars on the market today because it offers excellent properties at an affordable price point. For example, Monel 400 round bar can be used to make springs that are up to 10 times harder than steel without any loss in elasticity or resilience.

It is also known as Alloy 400 round bar which is a material used in the manufacturing of aircraft, rockets, and missiles. It is mostly used for its high strength-to-weight ratio and corrosion resistance. Monel 400 bar is a type of metal that has a high melting point and good heat conductivity. This makes it a good choice for applications such as aerospace, nuclear reactors, and power plants.

The benefits of using Alloy 400 round bar include:

  • High nickel content makes it resistant to corrosion

  • It is a strong, lightweight material that has good ductility and toughness

  • Monel 400 round bar has excellent resistance to friction and wear

Buy Monel 400 Round Bar from PGB

Alloy 400 round bar is a type of stainless steel that is commonly used in many industries such as construction, marine, transportation, aerospace, and nuclear power. It has good resistance to corrosion and oxidation and has high tensile strength. It is typically used in the manufacturing of valves, gears, bearings, fasteners, and other products that require high-strength materials.

Monel 400 bar has a number of benefits over the other types of alloys. It is highly resistant to corrosion and oxidation, which means it can be used in corrosive environments without any problems. It also has a high strength-to-weight ratio, making it ideal for use in heavy-duty applications. Not only that, Alloy 400 round bar is often used in marine applications because it does not corrode easily and does not oxidize easily either.
