Materials Development Case Studies

Starting from component requirements, define the boundaries of materials, processes, and validation

Original case study image of domesticating steering knuckle ball joint materials

Localization of steering ball head materials

In response to the demand for domestic substitution of imported steering ball heads, we have developed 41CrS4 material. The case focuses on its compatibility with high-strength, large-strain forming and subsequent turning operations.

Material: 41CrS4
Applicable standards for the case: EN 10263

The specific delivery condition, mechanical properties, and trial production acceptance criteria shall be governed by the project’s technical agreement.

Example of a custom part with special mechanical properties; this is not an actual photograph of the weld stud.

Weld studs for airbag detonation tubes

For weld studs used in airbag detonator tubes, we provide customized materials with tailored mechanical property windows.

Materials and Specifications: SWCH10A · 6.30 mm
Case Tensile Strength: 380–420 MPa

The above values represent the material requirements for this specific case and do not constitute guaranteed values for all specifications under the same grade.

Shaped Profile for the Seat Belt Locking Block

Replacing the powder metallurgy route with a shaped profile, we develop material solutions based on the cross-sectional geometry of the seat belt locking block and its subsequent machining processes.

Application Part: Seat Belt Locking Block
Development Direction: Substitution of Shaped-Section Materials and Process Routes

Changes in mechanical properties and costs depend on the part, the original process, and mass-production conditions, and must be verified on a project-by-project basis.
