Forging Mild Steel
Hole Position Accuracy ： ≤0.1 mm
Minimum Order Quantity ： 200 pcs
Weight Range ： 0.5g–500kg
Forging Mild Steel strictly follows the German DIN EN 10250 standard and adopts closed-loop temperature-controlled forging process. To ensure metallic purity, the sulfur and phosphorus impurity content is kept to ≤0.015% using vacuum degassing technology, and the material purity is as high as over 99%. Near-net forming is accomplished by carefully controlling the tolerance of single batch parts to ±0.1mm and stabilizing the mold temperature during the forging stage within the range of ±5°C.
Isothermal normalizing treatment is used throughout the entire process to ensure that the grain size reaches a stable ASTM 6-8 grade uniform fine-grained structure, significantly improving fatigue resistance. After forging, controlled cooling is performed at a rate of ≤2℃/s to completely eliminate internal stress. Final products are subjected to ultrasonic flaw detection and 100% three-dimensional verification to guarantee the delivery of critical load-bearing components, such as precision transmission parts and high-pressure valve bodies, without any defects.

Applications
our casey
Hydraulic valve blocks for construction machinery
Forged from low-carbon steel, precision die-forged to control valve flow tolerances, ensuring leak-free operation of high-pressure oil.
The ultra-fine grain structure can withstand more than 30 pressure shocks per minute, and the vacuum degassing process eliminates pitting failure caused by sulfides.
Controlled cooling after forging eliminates internal stress and extends the life of the excavator's multi-way valve.
Wind Turbine Bearing Support
The material purity exceeds 99% to resist salt spray corrosion, and isothermal normalizing creates uniform, fine grains that enhance fatigue resistance.
The overall structure of the forging supports the radial load of the megawatt-level transmission chain and avoids the initiation of intergranular cracks during the twenty-year service life. Ultrasonic flaw detection ensures zero internal defects.
Industrial Pressure Pipe Flange
Forged, dense metal streamlines block media penetration paths, and the ultra-low sulfur and phosphorus content achieves EU pressure equipment certification.
The hydraulic bulging process achieves micron-level sealing surface flatness, maintaining bolt preload stability under high-temperature steam conditions and eliminating flange leakage.
Semiconductor Equipment Positioning Bracket
Near-net-net forging enables one-piece molding of complex curved surfaces, preventing welding deformation from interfering with optical path alignment.
Magnetic particle inspection ensures that there are no magnetic inclusions and prevents particles from falling off and contaminating the wafer.
Constant temperature treatment maintains millimeter-level assembly hole spacing stability and supports the nano-precision motion platform of the lithography machine.
