Engineering focus: Stainless steel powder manufacturing and customization
Review the material, particle-size, process and validation factors that matter for this application.
The material family determines the basic direction of strength, hardness, wear resistance, corrosion resistance and heat treatment.
Particle size distribution affects filling, flow, sintering activity, shrinkage and surface condition.
The same powder may produce different part results under different equipment and process windows.
Stainless steel powder range
The products cover precipitation hardening, martensitic and ferritic stainless steel powders. 17-4PH takes into account strength, corrosion resistance and heat treatment response; 440C is oriented to high hardness and wear-resistant parts; 439 is suitable for corrosion resistance and thermal cycle direction; 17-4+3Cu is communicated separately according to Tongcheng's existing product name as a project-type material.

- 440C Martensitic stainless steel powder
- 439 Ferritic stainless steel powder
- 17-4+3Cu Project type stainless steel powder
For MIM and powder metallurgy
Tongcheng synergistically matches particle size distribution, flow filling, sintering activity, shrinkage and final properties based on metal injection molding, pressing and sintering and other powder metallurgy routes.
Custom alloy and particle size
When standard grades cannot meet the hardness, wear resistance, corrosion resistance, strength or sintering window requirements, Tongcheng can develop a powder solution from the four links of alloy formulation, in-house atomization, sieving and blending, and customer trial production.
