APPLICATION SUMMARYApplication notes

440C stainless steel powder can be used for scissors and cutting components requiring high hardness, wear resistance and edge retention, including complex geometries made by MIM.

APPLICATION GUIDE

Engineering focus: 440C stainless steel powder for scissors

Review the material, particle-size, process and validation factors that matter for this application.

Part requirementsMaterial or process directionSelection guidance
MaterialPrioritize evaluation 440C High hardness and wear resistance direction

Edge retention and friction life are usually the primary goals.

manufacturingMIM Complex structure combines sintering, heat treatment and grinding

Forming advantages require subsequent processes to be jointly converted into edge performance.

EvaluationHardness, toughness, cutting edge, size and shear life

It cannot be judged by powder particle size or single hardness alone.

01

Why choose 440C

440C can obtain high hardness and wear resistance after proper heat treatment, suitable for scissor blades, shearing mechanisms and precision parts that need to maintain sharpness.

02

Manufacturing Advantages of Powder Forming

MIM can produce curved surfaces, holes, ribs and complex connection structures, reducing cutting processing; particle size and feedstock status will affect thin-wall filling, sintering deformation and surface quality.

03

Support available from Tongcheng

Provides 440C powder, particle size parameters and forming and sintering technology recommendations, and can tailor solutions around hardness, edge, size and surface targets.

Suitable part characteristics

Part requirements to evaluate first

  • Scissor blades, shearing structures and complex small tool parts
  • Focus on projects with high hardness, wear resistance and edge retention
Confirm before selecting the material

Also consider these manufacturing conditions

  • Material being cut, load, cutting-edge angle and service-life requirements
  • Heat treatment, sharpening, polishing and assembly routes
