Manufacturers specializing in carbon steel round bars offer a range of types, features, and specifications to meet different applications and performance requirements. Let’s delve into the types, features, and specifications of carbon steel round bars from leading manufacturers in the industry.
Types of Carbon Steel Round Bars
Mild Carbon Steel Round Bars:
Mild carbon steel round bars, also known as low carbon steel bars, have a carbon content typically below 0.30%, making them easy to weld, form, and machine. They are used in general-purpose applications such as construction, fabrication, and DIY projects.
Medium Carbon Steel Round Bars:
Medium carbon steel round bars have a higher carbon content ranging from 0.30% to 0.60%, providing increased strength, hardness, and wear resistance compared to mild carbon steel. They are suitable for shafts, gears, axles, and machinery components requiring higher tensile strength.
High Carbon Steel Round Bars:
High carbon steel round bars contain carbon content above 0.60%, offering excellent strength, hardness, and abrasion resistance. They are used in applications such as cutting tools, springs, knives, and automotive components where high wear resistance is essential.
Free-Cutting Carbon Steel Round Bars:
Free-cutting carbon steel round bars are alloyed with elements such as sulfur, lead, or selenium to improve machinability, chip formation, and tool life during machining processes. They are commonly used for precision components, fasteners, and fittings.
