41CrS4 · 10B38
Collaborative development of special materials in alignment with project requirements.
Professional Capabilities 01 / 05 · Material Development
For special parts,
develop the right material.
When conventional grades cannot meet the requirements, collaborate with steel mills to develop chemical composition, smelting routes, and delivery conditions, and organize trial production and application validation.
The customer’s requirements
First, translate the part requirements into material specifications.
Conventional grades are insufficient
The part’s strength, ductility, heat treatment, or processing requirements necessitate further coordination of material conditions.
Imported Material Substitution Assessment
Starting from raw-material standards, actual usage conditions, and acceptance criteria, we confirm differences and validation items one by one.
New parts and specialized material development
If the customer already has target part specifications, the material, feed form, and delivery condition need to be jointly determined.
Development approach
Working with steelmakers and customers to implement development specifications.
Requirements and Raw Material Review
Review part drawings, intended use, currently used materials, forming processes, and subsequent heat treatments to pinpoint the specific issues that need to be addressed.
Steel Plant Collaboration and Material Processing
Together with the steelmaker, assess composition, steelmaking and wire-rod conditions; Creation Group develops a processing plan covering annealing, drawing and surface treatment.
Trial production and application validation
Organize trial production and testing; have the customer validate based on actual parts and operating conditions, then confirm the technical agreement and delivery terms.
Projects and Case Studies
Existing projects involving special materials and custom grades
Current development projects involve the following materials. Specific compositions, processes, and supply conditions are confirmed for each individual project.
16MnCr5 · 10B21M · 34CrNiMo6
Organize material plans and trial production verification around the part’s application and processing conditions.
For certain special projects, trial production can begin with approximately 200 kg; suitability must be confirmed in conjunction with the steel plant’s production schedule, material conditions, and technical agreements.
Verification and Confirmation
Confirm materials and solutions using supporting evidence.
- Chemical composition and material source verification
- Inspection of as-delivered condition, microstructure, and mechanical properties
- Customer’s actual forming and validation of downstream processes
- Confirmation of Applicable Standards, Trial Production Quantities, and Acceptance Criteria
Initiate project communication
Bring this information along to make technical discussions more precise.
For materials already available, initial discussions can proceed; any unclear conditions will be further confirmed by both parties.
- Part Drawings, Applications, and Operating Conditions
- Currently used grades, standard versions, or material specifications
- Existing issues and target performance
- Specifications, trial production quantity, and downstream processing requirements
A development project does not automatically mean the material is directly substitutable. The specific material, trial-production quantities, performance characteristics, and supply terms shall be governed by the technical review and the mutually agreed technical agreement.
