Ferritic stainless steel powder suits applications balancing corrosion resistance, thermal cycling, magnetic behavior and cost. Tongcheng focuses on 439 powder and application support.
Compare more than the grade: define the powder delivery condition
Include the target material, particle size, manufacturing process and purchasing requirements so Tongcheng can quickly assess a standard powder, particle-size adjustment or custom development.
- Material and composition
- Ferritic stainless steel powderPlease also indicate the target grade, reference standards or current materials.
- Particle size distribution
- Specify D10, D50 and D90 values or a sieve-size rangeSelect in conjunction with MIM, pressing and sintering, part wall thickness, and fill requirements.
- Powder process data
- Density, flow and sampling methods are confirmed by projectDifferent test methods and forming routes require the use of comparable data.
- Chemistry and Interstitial Elements
- Determine items of concern based on material system and customer processComposition, carbon, oxygen, nitrogen or other inspection requirements may be stated in the inquiry.
- Packaging and supply
- Quantity, packaging unit, label, delivery date and destination countryUsed to check production arrangements, commercial quotations and export deliveries.
Engineering focus: Ferritic stainless steel powder
Review the material, particle-size, process and validation factors that matter for this application.
Suitable for screening material families based on usage environment and cost.
Tongcheng has D10, D50 and D90 particle-size data for its 439 powder.
The applicability of the same grade in different environments requires specific analysis.
Material characteristics of ferritic stainless steel
Ferritic stainless steel is suitable for parts that focus on corrosion resistance, thermal cycle, magnetism and economy, and can cover industrial structural parts, heat-resistant parts and automotive-related applications.
439 stainless steel powder
In the volume-based particle size test record dated 2026-03-28, Tongcheng 439 powder has D10 of 2.955 μm, D50 of 9.896 μm and D90 of 27.944 μm. These are the results of that test; when selecting material for MIM or other powder metallurgy routes, the particle size specification for supply is confirmed for each project.
particle size and Manufacturing Support
Tongcheng can provide particle size solutions and batch supply support based on part wall thickness, filling flow, sintering and surface requirements.
