Carbon, oxygen, residual binder and sintering atmosphere will affect the densification, phase composition, surface state and corrosion resistance of stainless steel and should be controlled separately according to the material system.
Interpret the relationships between variables, not a single parameter
Explain the effects of carbon, oxygen, residual binder and sintering atmosphere on densification, surface and properties.
Powder and debinding will bring variables
Powder surface condition, binder residue and debinding integrity all affect carbon and oxygen conditions upon entry into the sintering furnace.
Atmosphere is not a universal parameter
The suitability of hydrogen, vacuum or other controlled atmospheres depends on materials, equipment, safety requirements and target performance and cannot directly replicate other manufacturers' sintering conditions.
Connect chemistry data to performance
When density, hardness, surface quality or corrosion resistance is abnormal, evaluate C/O/N data together with furnace-run records, metallography and finished-part test results.
Discuss your powder project
Share the process step, operating conditions and part result you want to improve.
- Current material, powder or part issue
- Process step and observed symptom
- Available particle-size, composition, dimensional or performance data
- Equipment, process conditions and desired outcome
