4130,4140,C45,C60 Non-Standard Sizes Alloy or Carbon Steel Custom Forging Blanks
Custom Open Die Forging Blanks in Non-Standard Sizes | 4130, 4140, C45, C60 Alloy & Carbon Steel
We specialize in open die forged blanks made from 4130, 4140, C45, and C60 carbon and alloy steels, tailored to non-standard sizes and customer specifications. Ideal for gear components, machinery parts, and industrial applications, our forgings offer excellent mechanical properties, dimensional accuracy, and reliable performance.
With over 25 years of forging experience, we support small-batch orders, provide full material certificates (EN10204 3.1/3.2), and have long-term experience exporting to European markets. All forging blanks are produced under strict quality control with in-house inspection and rough machining capabilities.
Rough blanks of large steel forgings are the foundational components used across a wide range of heavy-duty industries, including energy, marine, mining, and industrial equipment. They are forged to near-net shapes, offering an optimal starting point for precision machining and final processing.
