Blades and cutting components typically require a balance of hardness, wear resistance, edge retention, toughness and corrosion resistance. Evaluate 440C or custom stainless steel powder according to the service conditions.
Engineering focus: Stainless steel powder for blades and cutting parts
Review the material, particle-size, process and validation factors that matter for this application.
Different loads determine the balance of hardness and toughness.
The final choice needs to be made in conjunction with sintering density and heat treatment.
A single hardness value cannot represent actual cutting performance.
First distinguish between cutting and impact conditions
Continuous sliding cutting, shearing, scraping and intermittent impact have different requirements on hardness, toughness and wear mechanism. Materials cannot be selected just by the name of 'blade'.
Material and heat treatment determine the cutting edge
440C can be used as a high-hardness wear direction, but final edge performance is also related to sinter density, heat treatment, grinding, edge angle and surface defects.
Powder forming is suitable for complex small parts
MIM can be further compared to the manufacturing boundaries of machining when insert attachments, cutting heads, or edge parts have holes, curved surfaces, and connections.
Part requirements to evaluate first
- Insert attachments, cutting heads and complex small edge parts
- Focus on projects with high hardness, wear resistance and mass forming
Also consider these manufacturing conditions
- Material to be cut, load, speed, edge angle and life
- Heat treatment, grinding, surface and assembly requirements
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
