ASTM A276 and ASTM A479 Nickel Alloy Round Bar Weight, Dimensions Chart in mm, kg, PDF online

Nickel alloy round bars are solid cylindrical bars made from various alloys of nickel. In these alloys, nickel forms the main part along with other elements. These round bars are commonly made from nickel-copper alloys (e.g., Monel), nickel-chromium-iron alloys (e.g., Inconel), and pure nickel. These alloy consist of different percentages of elements mentioned above, different in each alloy. The choice of alloy depends on the specific application and the required properties, such as corrosion resistance, high-temperature strength, or low-temperature toughness. Detailed information on these alloys can be obtained in nickel alloy round bar weight and dimensions chart PDF.

Nickel alloy round bars are corrosion-proof and rust-free, which makes them suitable for use in extreme conditions. Nickel alloys has higher mechanical strength. This increased strength allows for the use of smaller-diameter round bars, reducing weight and cost while preserving structural integrity. This characteristic is advantageous in various high-stress applications. Nickel alloy round bars can be machined using standard machine tools, but it's important to use appropriate cutting tools and techniques due to their higher strength and durable properties. Different types of nickel alloy round bars are Monel Round Bars (Alloy 400), Inconel Round Bars (e.g., Inconel 600, Inconel 625), Hastelloy Round Bars (e.g., Hastelloy C276, Hastelloy C22), Nimonic Round Bars (e.g., Nimonic 75, Nimonic 90), Incoloy Round Bars (e.g., Incoloy 800, Incoloy 825), Alloy 20 Round Bars(Carpenter 20), Nickel 200/201 Round Bars, Alloy 625 Round Bars and various other alloy round bars. Nickel alloy round bars come in a variety of sizes and diameters to suit different applications. Nickel alloy 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. For knowing about these standards and specifications in detail, refer to weight and dimensions chart given in mm and kg units, below.

Nickel alloy 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
