1060 Steel
Introduction to 1060 Steel: High-Carbon Steel for Increased Strength and Hardness
1060 steel is a high-carbon steel with a carbon content of approximately 0.60%, offering a significant increase in strength and hardness compared to lower-carbon steel. This material is commonly used in applications with critical wear resistance and strength. With a tensile strength of around 700 MPa and a yield strength of 450 MPa, 1060 steel excels in heavy-duty environments where durability is essential, such as in producing tools, knives, and cutting components.
Although 1060 steel offers superior strength, it is more challenging to machine than lower-carbon steel due to its hardness. However, it is widely favored in industries where its mechanical properties can be fully leveraged. CNC machining of 1060 steel results in parts with high strength and precise tolerances, which are essential for high-stress applications. At Neway, CNC-machined 1060 steel parts are processed to meet the highest dimensional accuracy and durability standards.
