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

Incoloy round bars are solid cylindrical bars made from incoloy, a group of nickel-chromium-based alloys. Incoloy round bars are typically made from incoloy grades, with common grades being Incoloy 800, Incoloy 800H, Incoloy 800HT, Incoloy 825, and Incoloy 925. These alloys primarily consist of nickel, chromium, iron, and smaller amounts of other alloying elements like molybdenum, copper, and titanium. Detailed information on these grades can be obtained in incoloy round bar weight and dimensions chart PDF.

Incoloy round bars are corrosion-proof and rust-free, which makes them fit for use in aggressive environments. Incoloy has higher mechanical strength. This increased strength allows for the use of smaller-diameter round bars, reducing weight and cost while maintaining structural integrity. This property is advantageous in various high-stress applications. Incoloy 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 work-hardening properties. Different types of incoloy round bars are hot-rolled round bars, cold-rolled round bars, and forged round bars. Incoloy round bars come in a variety of sizes and diameters to suit different applications. Incoloy 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.

Incoloy 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
