Shanxi Jianing Forging regularly stocks 20#, A105, 45#, and other standard carbon and high-quality carbon steel raw materials. The station has complete real-world cases of carbon steel flanges, shafts, and ring forgings. Carbon steel forgings offer high cost performance and are suitable for manufacturing general industrial equipment.
A construction machinery parts factory in Hefei, Anhui, has long purchased carbon steel forgings for load-bearing structural parts of loaders, excavators, and other equipment. The factory's original suppliers had shortcomings in internal microstructure density, dimensional consistency, and delivery cycles, affecting the assembly efficiency and service life of the entire machine. After multiple rounds of evaluation, the plant ultimately chose to establish a long-term partnership with Jianing Forging, which would supply various specifications of carbon steel forgings in bulk.
(1) The internal structure of the forging is uneven, with some batches showing looseness and segregation, resulting in large hardness fluctuations after heat treatment and making early wear or fracture easy after assembly.
(2) Unstable control of forging dimensional tolerances and poor matching with machining allowances increase subsequent cutting costs and scrap rates.
(3) Supplier delivery cycles are long, urgent order responses are slow, affecting production line scheduling and complete machine delivery.
To address these pain points, Jianing Forging offers the following solutions:
(1) Using high-quality carbon structural steel (such as 45#, 40Cr) as raw materials, combined with multi-pass temperature-controlled forging processes, refine internal grains and reasonable flow distribution, thereby improving density and mechanical stability.
(2) Introduce fine mold design and forging equipment, using an online dimensional monitoring system to keep key dimensional tolerances of forgings within ±0.3mm, reducing subsequent machining allowances.
(3) Establishing safety stock and rapid mold change mechanisms: regular orders are scheduled within 48 hours, urgent orders can be expedited within 24 hours, helping customers maintain uninterrupted production.
