Anucha Metals, a reputable manufacturer and supplier located in Bangkok, Thailand, specializes in high-quality C45 Round Bars designed for strength, durability, and precision. C45 is a medium carbon steel grade that’s well-known for its impressive toughness, high tensile strength, and good machinability. At Anucha Metals, we offer C45 Round Bars in a variety of sizes and dimensions, meeting the demands of industries like automotive, engineering, construction, and machinery manufacturing. Our products are crafted under strict quality control measures to guarantee consistent performance, reliability, and a long service life. With competitive pricing and prompt delivery, we’ve become a go-to source for C45 Round Bars.
C45 Round Bar mainly consists of carbon (0.42–0.50%), manganese (0.50–0.80%), silicon (up to 0.40%), along with controlled amounts of sulfur and phosphorus. This blend provides excellent strength, hardness, and wear resistance after heat treatment. In terms of mechanical properties, it boasts a tensile strength of 570–700 MPa, a yield strength of about 330 MPa, and good elongation. C45 steel is perfect for hardening through quenching and tempering, which further boosts its toughness and strength. Its well-rounded mechanical properties make it an ideal choice for machining, forging, and producing critical machine components that endure stress.

Yes, C45 Round Bar can be recycled and repurposed without losing its essential properties.
C45 Round Bar does not have a specific pressure rating, as it is primarily used for mechanical and structural applications, not pressure-bearing components.
Yes, C45 Round Bar may require corrosion protection coatings when exposed to harsh environmental conditions to prevent rust and degradation.
C45 Round Bars are a go-to choice in industries that need strength and wear resistance. You’ll often find them in the manufacturing of machinery parts, shafts, axles, crankshafts, bolts, gears, studs, spindles, and couplings. In the automotive world, they play a crucial role in engine and transmission components. The engineering and construction sectors also rely on C45 for crafting tools, machine parts, and fasteners that demand durability and toughness. When heat-treated, C45 becomes perfect for applications that face dynamic loading and high impact. Plus, its excellent machinability allows for precise shaping, making it a favored material for industrial equipment, heavy-duty components, and mechanical parts that need to perform reliably.
