Engineering focus: 17-4+3Cu stainless steel powder
Review the material, particle-size, process and validation factors that matter for this application.
This material is project-oriented and should not directly replace existing grades by name alone.
Particle size needs to be evaluated along with alloy composition, sintering and heat treatment.
Product names do not replace material specifications and need to be confirmed according to the actual project.
Confirm material definition according to project requirements
17-4+3Cu is listed under Tongcheng’s current product designation. Before purchasing or selecting the material, confirm the target composition, reference material, heat-treatment condition and required part properties. The designation should not be assumed to be equivalent to an international standard grade.
From alloy formulation to powder manufacturing
Tongcheng can carry out alloy formulation, in-house atomization, particle size adjustment and customer process verification based on reference materials, target composition and part usage, so that project-type materials can enter the customer's MIM or powder metallurgy process.
Particle size and application parameters
The volume-based particle size test record dated 2025-05-06 shows D10 of 2.564 μm, D50 of 9.150 μm and D90 of 30.916 μm for 17-4+3Cu. The particle size specification for supply is confirmed for each project. The engineering team can provide technical support based on sintering, heat treatment, dimensional and performance targets.
