Can the heat treatment cycle for H13 material be shortened?

With expedited service and process optimization, the heat treatment cycle for H13 material can be reduced to one to three days while maintaining quality. However, important procedures (including tempering and heat preservation) cannot be skipped because doing so could result in uneven hardness or cracking concerns.

Within six to twelve hours, the report was released.

Real-world example: Using an expedited channel, a Wuhan company reduced the heat treatment cycle from three days to forty-eight hours.

 

2. Core Process Time That Is Incompressible

Quenching and Holding: To prevent "incomplete quenching," the workpiece's core temperature must be consistent, holding for one hour for every 25 mm of thickness.

Tempering Time: To avoid excessive residual stress, there should be at least two tempering cycles, each lasting more than two hours.

Nitriding Procedure: Gas nitriding is a lengthy process that takes 40 to 60 hours. It shouldn't be drastically shortened as this will impact the bonding strength and layer depth.

Risk Warning: The pass rate will drop by 5% to 15% if any steps are skipped or the holding time is shortened.

 

3. Safety and Acceleration Suggestions

Select a local service provider with multi-furnace collaboration capabilities, like Wuhan Heat Treatment Plant or Jingmo Technology, to facilitate accelerated processing.

Combine batch processing: By processing several components in a single furnace, waiting times are shortened and productivity is increased.

Avoid tight synchronization with the final heat treatment by finishing the stress-relieving tempering beforehand.

Safety Principle: "Fast is acceptable, but not labor-saving," which guaranties that cooling, time, and temperature are all under control.
