Hydrogen Embrittlement Bake: 350°F for 3 Hours – Targeted Stress Relief for Plated Parts

Metal Finishing Group provides a specialized Hydrogen Embrittlement Relief Bake at precisely 350°F for a duration of 3 hours. This critical post-plating heat treatment is specifically designed to mitigate the risk of hydrogen embrittlement in susceptible components, ensuring their long-term integrity and performance. Hydrogen embrittlement, often introduced during electroplating, can lead to delayed brittle fracture in high-strength steels if not properly addressed.

This targeted baking process is chosen when components require efficient hydrogen diffusion within a specific temperature and time window to restore ductility and prevent brittle failure. It is ideal for a range of critical parts across industries where defined baking parameters are essential for compliance and reliability under stress. Our precise control over temperature and duration ensures consistent and effective hydrogen removal, safeguarding the functionality of your plated components.

Our 350°F / 3 Hour Bake Capabilities: Consistent Relief and Reliability

We offer precise baking services, ensuring optimal hydrogen embrittlement relief with our specialized 350°F for 3 hours process.

  • Fixed Temperature and Duration: Components are consistently heated to 350∘F for a precise duration of 3 hours, a parameter often specified for particular materials or plating processes.
  • Hydrogen Diffusion: This controlled heat treatment effectively diffuses hydrogen atoms from the metal’s crystalline structure, preventing them from accumulating at grain boundaries and causing embrittlement.
  • Prevention of Brittle Fracture: Actively prevents hydrogen embrittlement, significantly reducing the risk of catastrophic failure under stress or load.
  • Material Compatibility: Primarily applied to electroplated components made from steels susceptible to hydrogen embrittlement, where this specific bake cycle is mandated.
  • Precision Equipment: We utilize calibrated ovens with accurate temperature and time controls to ensure each batch adheres strictly to the required parameters.
  • Batch Processing: We accommodate various part sizes and batch volumes efficiently while maintaining the integrity of each component.

Properties of Our 350°F / 3 Hour Bake:

This specific baking process imparts several key properties, enhancing the performance and safety of plated components:

  • Restored Ductility: Helps restore the original ductility of the base metal, which can be temporarily compromised by hydrogen absorption during plating.
  • Increased Reliability: Significantly reduces the likelihood of brittle fracture, particularly in parts subjected to dynamic or static loads.
  • Enhanced Fatigue Life: Mitigates the detrimental effects of hydrogen on the fatigue strength of susceptible materials.
  • Maintained Material Integrity: Ensures the mechanical properties and intended performance of the plated part are fully preserved.
  • Compliance: Meets specific industry and customer requirements for hydrogen embrittlement relief where this particular bake cycle is mandated.

Applicable Specifications We Adhere To:

Our 350°F / 3 Hour baking process consistently meets or exceeds crucial industry standards and customer specifications, ensuring the quality and performance of your components. We regularly process to:

  • ASTM B850: Standard Guide for Post-Coating Treatments of Steel for Reducing the Risk of Hydrogen Embrittlement, where this specific bake cycle may be referenced or permitted.
  • AMS 2750: Pyrometry (for precise oven calibration and temperature control).
  • Customer-Specific Requirements: We meticulously follow engineering drawings and specifications that explicitly call for a 350°F bake for 3 hours for hydrogen embrittlement relief.

Typical Applications for Our 350°F / 3 Hour Bake:

This specialized baking is vital for numerous applications across industries where hydrogen embrittlement is a concern and this specific bake cycle is required:

  • Automotive Components: Used for plated fasteners, springs, and critical under-hood parts made from steels that benefit from this particular bake cycle.
  • General Industrial Hardware: Applied to various plated components in machinery and equipment where specific embrittlement relief parameters are mandated.
  • Certain Fasteners: Ensures the structural integrity of plated bolts, nuts, and screws made from susceptible alloys, reducing the risk of delayed failure.
  • Springs and Clips: Guarantees the continued performance and durability of plated springs and resilient components.
