AISI 1035 Steel, cold drawn, 19-32 mm (0.75-1.25 in) round Product Information -:- For detailed product information, please contact sales. -: ### **Product Technical Specification: AISI 1035 Steel - Cold Drawn Round Bars (19-32 mm / 0.75-1.25 in)** --- #### **1. Product Overview** AISI 1035 cold drawn round bars are precision-engineered medium-carbon steel products manufactured through a cold drawing process that significantly enhances their mechanical properties, dimensional accuracy, and surface quality. This process involves pulling hot-rolled bars through a carbide die at room temperature, resulting in strain hardening and superior geometric characteristics. The 19-32 mm (0.75-1.25 in) diameter range represents one of the most commonly utilized sizes for precision mechanical components across diverse industries, offering optimal balance between strength and manufacturability. --- #### **2. Key Characteristics & Advantages** - **Enhanced Mechanical Properties:** Cold working increases yield strength by 20-30% compared to hot-rolled equivalents - **Superior Dimensional Accuracy:** Maintains tight diameter tolerances (typically ±0.075 mm / ±0.003 in or better) - **Excellent Surface Finish:** Produces smooth, scale-free surface (1.6-3.2 µm Ra / 63-125 µin Ra) ideal for bearing applications - **Improved Straightness:** Essential for rotating components and linear motion systems - **Better Machinability:** Provides more consistent and predictable machining characteristics than as-rolled material - **Good Heat Treatment Response:** Readily responds to quenching and tempering for additional strength enhancement --- #### **3.
