Top 5 Things to Know Before Buying C45 Carbon Steel
Introduction
C45 carbon steel is one of the most widely used medium carbon steels in the manufacturing and engineering industries. Known for its high strength, wear resistance, and machinability, C45 plays a key role in components requiring toughness such as axles, gears, shafts, and more. At The Steel Mart, we specialize in the supply and distribution of premium quality C45 carbon steel products. Whether you're a first-time buyer or an industry veteran, understanding the core attributes of C45 carbon steel before buying is critical. In this comprehensive guide, we break down the top five things you need to know before making a purchase.
1. Know the Properties and Composition of C45 Carbon Steel
C45 is a medium carbon, medium tensile steel supplied in the black hot-rolled or normalized condition. It is well-suited for components that require better mechanical properties than mild steel but do not require alloy steel.
Chemical Composition:
Carbon: 0.42–0.50%
Manganese: 0.50–0.80%
Silicon: ≤ 0.40%
Sulphur: ≤ 0.035%
Phosphorus: ≤ 0.035%
Mechanical Properties:
Tensile Strength: 570–700 MPa
Yield Strength: 330 MPa (min)
Hardness: 170–210 HB
These attributes make C45 suitable for applications where moderate tensile strength and impact resistance are required.
2. Understand the Heat Treatment Options and Effects
C45 carbon steel can be heat-treated to increase its mechanical strength and hardness. The mos
