Tongcheng provides 440C, 17-4PH and customized stainless steel powder for tool parts with high hardness, wear resistance, dimensional accuracy and complex shapes.
Engineering focus: Stainless steel powder for precision tools
Review the material, particle-size, process and validation factors that matter for this application.
Suitable for friction, cutting edges and high hardness directions.
Suitable for the balance direction of strength, corrosion resistance and heat treatment.
Consider alloy development when standard grades do not meet the requirements.
Applicable parts
Can be used for clamping parts, tool attachments, locking structures, wear-resistant connections, friction parts and other complex precision tool components.
Material selection
440C focuses on hardness and wear resistance, while 17-4PH takes into account strength and corrosion resistance; impact, corrosion, temperature and life requirements will affect the final grade.
Manufacturing technical support
The engineering team collaboratively optimizes the density, size, hardness and service life of tool parts from particle size, forming, sintering, heat treatment and surface processing.
Part requirements to evaluate first
- Complex precision tools, clamping parts, locking parts and friction parts
- Projects that require reduced machining while maintaining size and performance
Also consider these manufacturing conditions
- Contact loading, impact, wear and corrosive environments
- Heat treatment, surface finishing, tolerance and life testing
Discuss your powder project
Share the process step, operating conditions and part result you want to improve.
- Part name, geometry or drawing
- Load, wear, corrosion, temperature and service-life requirements
- Forming, sintering, heat-treatment and surface-finishing route
- Estimated monthly or annual volume and project stage
