Precipitation-hardening stainless steel powder balances strength, corrosion resistance and heat-treatment response. Tongcheng supplies 17-4PH and 17-4+3Cu products and custom-alloy services.
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
- precipitation-hardening 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: Precipitation-hardening stainless steel powder
Review the material, particle-size, process and validation factors that matter for this application.
Suitable for structural parts that need balanced performance rather than hardness or corrosion resistance alone.
A distinction should be made between standard products and custom developments based on target composition and heat treatment response.
The shape and sintering state before heat treatment will affect the final performance consistency.
Advantages of precipitation-hardening stainless steel
This material family is suitable for precision parts where strength, corrosion resistance, dimensional stability and heat treatment adjustability are important. It is commonly used in structural parts, tool hardware, consumer electronics and automotive components.
Tongcheng products and grades
17-4PH is a mature comprehensive performance direction; 17-4+3Cu is a project-type material name in Tongcheng’s existing data and needs to be confirmed separately based on the composition and target performance. Both materials present existing D10, D50 and D90 particle size data.
