Description
Product Description
Carbon/alloy square steel bar is ideal for many industrial products and applications where strength and durability are required. Characteristics of carbon steel bars are based on the carbon content. Increased carbon content will raise carbon steel's hardness and strength. Inversely, lower carbon content results in a softer (mild) carbon steel that is easier to machine and weld.The type of carbon steel needed is generally based on the application requirements. If you need assistance in determining the right carbon steel bar for your job our sales team is happy to help. Contact us on how we can help you with your next project.
