ASTM A276 and ASTM A479 Carbon Steel Round Bar Weight, Dimensions Chart in mm, kg, PDF online
Carbon steel round bars are solid cylindrical pieces of carbon steel that have a common usage in various
industries and applications due to their strength, durability, and versatility. Carbon steel is a type
of steel that primarily consists of iron and carbon, with trace amounts of other elements such as
manganese, phosphorus, sulfur, and silicon. The carbon content in carbon steel typically ranges from
0.05% to 2.0%. The exact composition and properties can change depending on the specific grade of carbon
steel, which can include low carbon steel, medium carbon steel and high carbon steel. They come in
various grades, more common grades include 1018, 1045, 1050, 1060, 1070, 1080, 1095, and many more.
Carbon steel round bar weight and dimensions chart are in PDF format given below.
Carbon steel round bars are available in a wide range of sizes, with diameters typically ranging from 1/4
inch to several inches. The machinability and weldability of these round bars depend on their grades and
applications. Carbon Steel round bars are resistant to corrosion and are tough, strong and hard. The
weight and dimensions chart are given in mm, kg units.
Tough, easy to clean, perfectly welded and finished, carbon steel round bars have some typical uses
which include the following:
- Construction
- Infrastructure
- Aerospace
- Manufacturing Machinery
- Automotive
- Fastners
- Tools and Cutlery
- Power Generation
