　　What is Carbon Steel Stamping?

　　Carbon Steel Stamping is a universal precision forming process specifically designed for carbon steel (iron-carbon alloy) sheets. It processes carbon steel sheets into various structural parts and functional parts through standardized or customized molds and stamping equipment. Carbon steel possesses characteristics such as economic cost (price only 1/2 of aluminum alloy and 1/3 of brass), wide strength range (tensile strength 210-1300MPa), good formability (mild steel elongation ≥25%), sufficient material supply, and strong processing compatibility. The stamping process achieves integrated and efficient mass production of parts, with core features of "triple core advantages of cost optimization, strength adaptability, and high mass production efficiency", making it suitable for universal mass production scenarios with comprehensive requirements on cost, strength, and production capacity.

　　Compared with stamping of aluminum, titanium, brass and other metals, its core difference lies in adapting to carbon steel's characteristics of "uniform texture, moderate toughness, and controllable cost". Stable forming can be achieved without complex process optimization, with low investment in molds and equipment. It is currently the most widely used and cost-effective metal stamping solution, covering the full range of needs from simple flat parts to complex structural parts.

　　How It Works

　　The core of carbon steel stamping is "balancing efficient mass production and strength adaptability". It adapts to the characteristics of carbon steel with different carbon contents through simple and mature process design, achieving a balance between mass production and quality stability. The key processes and control points are as follows:

　　Carbon Steel Sheet Preparation: Select carbon steel sheets with corresponding carbon contents (mild steel/medium carbon steel/high carbon steel) with a thickness of 0.3mm-12mm; pre-treatment includes surface cleaning (removal of oil and rust) and precision leveling (flatness error ≤0.015mm/m). Choose cold-rolled (high dimensional accuracy, suitable for precision parts) or hot-rolled sheets (low cost, suitable for structural parts) according to part precision.

　　Mold Adaptation and Process Design: Molds are made of Cr12MoV hardened steel or cemented carbide, with surface nitriding treatment (hardness ≥HRC 60). The mold clearance is adjusted according to carbon content (1.1-1.2 times the material thickness for mild steel, 1.05-1.1 times for high carbon steel), and fillet design (R≥0.3mm) reduces stress concentration; the blank holder applies pressure (0.5-3MPa) to adapt to the forming resistance of different carbon steels.

　　Precision Stamping Forming: Select equipment (mechanical punch press, CNC punch press, hydraulic punch press) according to
