Localized Stress Relief (LSR)

Byron Products offers high quality heat treatment services, which includes our Localized Stress Relief (LSR) process. LSR refers to the normalizing process on a targeted area (such as a weld seam) in a controlled environment which does not affect the tolerance of the surrounding base metal.  LSR is mostly utilized in the overhaul and repair of aerospace engine and land-based turbine components.  

An Effective Local Heat Treatment

Localized Stress Relief is a local heat treatment which, as the name implies, involves the application of heat to anneal stresses in a targeted area. It’s performed by heating the affected area to a specific temperature using cartridge or ceramic heaters.   An argon heat gun can also be used in certain scenarios for more precise results.

Following the prescribed temperature hold cycle, the area is cooled to spec. The result is a more stable microstructure on the affected area, reducing the risk of failure on the repair site. 

Benefits of Localized Stress Relief and Stress Relieved Steel:

• Minimizes, reduces, or eliminates residual stresses present after welding
• Prevents premature failure of a part
• Lowers risk of post-op dimensional changes 
• Avoids need to heat treat entire part

Applications of Localized Stress Relief

• Aerospace engine components
• Land-based turbines
• Pressure vessels
• Multiple-material assemblies 
• Machining defect and Weld repair
  

Both large and small assemblies are benefited by stress relief heat treatment processes that require weld repair following machine defects.  Local heat treatment is a crucial process in any industry with overhaul and repair needs, and Byron Products is a spearheader in LSR solutions and heat treating service.
