ASTM A276 and ASTM A479 Monel Round Bar Weight, Dimensions Chart in mm, kg, PDF online
Monel round bars are solid cylindrical bars made from Monel, a family of nickel-copper alloys known for
their outstanding corrosion resistance, high-temperature strength, and durability. These round bars find
applications in various industries where resistance to harsh environments and corrosive substances is
critical. Monel round bars are typically manufactured from Monel alloy grades, with Monel 400 (UNS
N04400) and Monel K-500 (UNS N05500) being the most commonly used. Monel 400 consists primarily of
nickel (approximately 67%) and copper (approximately 28%). It also contains small amounts of iron,
manganese, carbon, and other trace elements. Monel K-500 is a precipitation-hardened alloy that includes
additional elements such as aluminum and titanium, which contribute to its enhanced mechanical
properties. Detailed information on these different types of monel alloys can be obtained in monel round
bar weight and dimensions chart PDF.
Monel round bars are corrosion-proof and rust-free, which makes them suitable for use in aggressive
environments. Monel round bars come in various forms. They are available as solid round bars which are
solid cylindrical bars with a consistent diameter throughout their length, as hollow round bars which
have a hollow center and are used in applications where weight reduction or specific mechanical
properties are required and as precision ground round bars. Monel round bars have high strength,
resistant to corrosion and, high temperatures and pressures, tough and easily weldable. Monel round bars
are manufactured according to various international standards and specifications to ensure quality and
compatibility with the intended application. Common standards include ASTM A276 and ASTM A479. They also
come in various sizes, all of which can be seen in the weight and dimensions chart below.
Monel round bars have some typical uses which include the following:
- Food and beverage processing equipment
- Pharmaceutical processing equipment
- Chemical processing equipment
- Nuclear power equipment
- Desalination equipment
- Marine engineering
- Water and wastewater treatment equipment
- General engineering applications
