Haihao Group’s custom ASTM A321 forgings meets stringent tolerances for Latvian client

Haihao Group recently completed a specialized order for a client in Latvia, demonstrating our expertise in custom forging and precision manufacturing. The client required a batch of approximately 50 forgings, produced to their exact specifications based on detailed drawings.

Custom ASTM A321 Forging Drawing

The material of choice was ASTM A321, a high-quality austenitic stainless steel known for its excellent corrosion resistance and high-temperature strength. The client’s specific requirements included controlled element content: C≤0.08, Si≤0.8, Mn≤2, Ni9-11, S≤0.02, P≤0.035, ensuring optimal performance in their intended application.

Precision was paramount in this project, with the client demanding an overall tolerance of ±0.1mm. Haihao Group’s advanced forging and machining capabilities allowed us to meet this stringent requirement, delivering forgings that precisely matched the client’s specifications.”

To further enhance the material’s properties, the finished products underwent a solution treatment process. This heat treatment ensures uniform microstructure and maximum corrosion resistance, crucial for the client’s application.

This successful project highlights Haihao Group’s commitment to providing tailored forging solutions that meet the unique needs of our international clients. We combine material expertise, advanced manufacturing techniques, and rigorous quality control to deliver exceptional results. Email:sales@haihaogroup.com
