APPLICATION SUMMARYApplication notes

Tongcheng supplies stainless steel powder for automotive precision parts, addressing corrosion, heat, strength, wear and volume-production requirements.

APPLICATION GUIDE

Engineering focus: Stainless steel powder for automotive precision parts

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

Part requirementsMaterial or process directionSelection guidance
Working conditionsTemperature, corrosion, load, fatigue and friction

Determine the main working conditions first and then select the material family.

Material direction17-4PH, 439, 440C or customized

Corresponding to the strength, corrosion resistance, thermal cycle and wear resistance directions respectively.

series production requirementsConsistent dimensions, batch traceability and continuous supply

Automotive projects need to connect material changes with part verification.

01

typical direction

Small transmission parts, sensor structural parts, fasteners, valve pump parts and wear-resistant connectors.

02

Materials and performance direction

17-4PH is suitable for high-strength corrosion-resistant structures, 439 can be oriented to thermal cycle and corrosion-resistant parts, 440C is suitable for wear and friction parts, and alloys can also be developed according to projects.

03

Volume manufacturing support

Tongcheng works with customers to meet temperature, corrosion, load, fatigue, dimensional and traceability requirements through alloy, particle size, sintering application and batch management.

Suitable part characteristics

Part requirements to evaluate first

  • Small transmission parts, sensor structures, valve pumps and wear-resistant connections
  • Projects focusing on thermal cycling, corrosion resistance, or continuous batch manufacturing
Confirm before selecting the material

Also consider these manufacturing conditions

  • Temperature profiles, media, loads and fatigue requirements
  • Customer standards, validation plans, traceability and change management
