For over 70+ years, SM Engineering Co. has provided reliable heat treating services that help manufacturers improve the strength, durability, wear resistance, and performance of metal components. Our team combines decades of experience with carefully controlled processes to deliver consistent, repeatable results that meet demanding industry specifications.
Whether you require a single production run or ongoing manufacturing support, we work closely with you to understand your application and recommend the most effective thermal processing solution.
What Is Heat Treating?
Heat treating is a controlled thermal process used to alter the physical and mechanical properties of metals. By carefully heating and cooling materials, manufacturers can enhance hardness, improve machinability, increase wear resistance, reduce internal stresses, and optimize performance for specific applications.
At SM Engineering, every heat treating process is performed with precision and close attention to temperature control, cycle consistency, and quality assurance to ensure dependable results.
Our Heat Treating Capabilities
We offer a wide range of industrial heat treating processes to support manufacturers across numerous industries.
Bright Annealing
Bright annealing is performed in a controlled atmosphere to prevent oxidation while improving ductility and relieving internal stresses. This process produces a clean, bright surface finish while maintaining dimensional accuracy.
Common Applications
- Stainless steel components
- Precision machined parts
- Medical devices
- Decorative metal products
- Electronic components
Bright Hardening
Bright hardening increases material hardness and wear resistance while preserving the surface finish. This process is ideal for components requiring improved durability without additional finishing operations.
Benefits
- Increased hardness
- Excellent surface appearance
- Improved wear resistance
- Reduced post-processing
Stress Relieving
Stress relieving reduces residual stresses created during machining, welding, forming, or manufacturing processes. Proper stress relief helps minimize distortion while improving stability during future machining or service.
Ideal for:
- Welded assemblies
- Precision tooling
- Machined components
- Structural parts
Carburizing
Carburizing introduces carbon into the surface of steel components, creating a hard, wear-resistant exterior while maintaining a tough, ductile core. This combination provides excellent performance in demanding applications.
Typical applications include:
- Gears
- Shafts
- Bearings
- Industrial machinery components
Deep Case Carburizing
For applications requiring increased case depth and superior wear resistance, deep case carburizing provides enhanced durability for heavily loaded or high-cycle components.
Normalizing
Normalizing refines grain structure, improves machinability, and creates a more uniform microstructure. This process is commonly used before additional machining or heat treatment.
Brazing
Brazing permanently joins metal components using a filler material while maintaining the strength and integrity of the base metals. Controlled furnace brazing provides consistent, high-quality joints suitable for demanding applications.
Sintering
Our controlled atmosphere sintering processes improve the density and mechanical properties of powdered metal components while maintaining precise dimensional tolerances.
