ASTM A276 and ASTM A479 Alloy Steel Round Bar Weight, Dimensions Chart in mm, kg, PDF online
Alloy steel round bars are solid cylindrical bars made from alloy steel materials. Alloy steel round
bars are primarily composed of iron and carbon, like standard carbon steel bars, but they contain
different quantities of alloying elements to improve their properties. Common alloying elements in alloy
steel round bars include chromium, molybdenum, nickel, vanadium, and manganese, among others. These bars
are normally used in various industries due to their excellent mechanical properties, including high
strength, hardness, toughness, and wear resistance. Alloy steel round bars are available in a broad
range of grades and sizes to suit different applications. Some common alloy steel grades used for round
bars include, but are not limited to Chrome-Moly Alloys, Stainless Steel Alloys, Tool Steels, Nickel
Alloys and Low-Alloy Steels. Alloy steel round bars are available in various sizes, typically defined by
their diameter (e.g., 1 inch, 2 inches) and length. The diameter can range from small sizes used in
precision applications to large sizes used in heavy machinery. For more information on grades and sizes,
check our alloy steel round bar weight and dimensions chart PDF in mm, kg units.
Tough, strong and corrosion resistant, alloy steel round bars have wide range of applications, including:
- Automotive components (e.g., crankshafts, axles)
- Aerospace components (e.g., landing gear, engine parts)
- Machinery and equipment manufacturing
- Oil and gas drilling tools
- Fasteners and bolts
- Marine equipment
- Chemical processing equipment
- Construction and structural components
