Cold Roll Round Bar 1018 Cold Finish offers a good blend of strength, some ductility, ease of welding and machining. 1018, the most popular of the cold-rolled steels, is chemically similar to A36 Hot-Rolled steel, but the finishing process offers superior surface finish and mechanical properties. It is typically used in pins, rods, shafts, spindles, and sprockets.

The 1018 carbon steel round bar offers excellent machinability and weldability, making it a popular choice for a wide range of fabrication and machine part applications. Its balance of strength and ductility also makes it suitable for shafts, pins, and rods.

This product is a 20mm diameter metric round bar supplied in a 72-inch length, providing ample material for larger projects or multiple cuts.

Online Metals does not provide custom pre-cutting for this item, so the bar is shipped in the standard 72-inch length. Customers can cut it to desired lengths after delivery.

1018 carbon steel is a low carbon steel and does not offer significant corrosion resistance, so it is best suited for indoor or dry environments unless additional protective coatings are applied.

This product is available from various warehouses as indicated on the website, and the shipping weight for a 72-inch 20mm round bar is calculated at checkout based on the total order quantity and shipping address.

This round bar has a diameter of 20mm and a length of 72 inches. It is made from 1018 carbon steel with a cold finish, offering a good balance of strength and machinability.

No, this product is shipped in the standard 72-inch length and is not available for custom pre-cutting. You will need to cut it to your desired length after delivery.

Yes, the 1018 cold finish round bar offers excellent machinability and ease of welding, making it ideal for applications such as pins, rods, shafts, spindles, and sprockets.
