ThermTech: Excellence in Normalizing Heat Treatment
Normalizing Heat Treatment for Various Steel Products
ThermTech is at the forefront of providing normalizing heat treatment across a range of steel products, ensuring homogenized grain structure, enhanced machinability, and optimized response to subsequent heat-treating processes. Our offerings span steel forgings, castings, machined parts, and investment castings.
Steel Forgings:
Steel forgings often undergo heat treatment due to their production at high temperatures which result in non-uniform microstructure and grain size. Normalizing steel offers a solution by:
- Heating forgings slightly above the austenitizing temperature, promoting atomic mobility and steel homogenization.
- Cooling in still air, with adjustable rates depending on desired hardness.
- Producing forgings that are easier to machine with uniform mechanical performance upon subsequent quenching and tempering.
Common Steel Grades: 4140, 4340, 8620, 4130, 1045.
Castings:
Castings can develop uneven microstructures due to inconsistent cooling post-casting. Normalizing helps in:
- Refining the grain structure, ensuring a balanced distribution of carbon content post-casting.
- Alleviating “segregation”, where alloy elements segregate during casting or hot rolling.
- Offering specialized services for Ductile Iron Castings, ensuring they conform to specific mechanical property requirements.
Our team, including two metallurgists, offers valuable insights into alloying and processing considerations, ensuring conformance to even the most stringent requirements for DCI parts.
Machined Parts:
Machined parts often require normalizing to:
- Refine grain structure, ensuring uniform carbon content distribution.
- Address issues like “banding” which occurs when alloy elements segregate during forging or hot rolling.
Investment Castings:
Investment castings, which cool in ceramic molds, can sometimes develop undesired microstructures and decarburization. Normalizing offers a way to homogenize the grain structure, improve machinability, and ensure better outcomes from subsequent heat treatments.
State-of-the-Art Facilities:
- All our normalizing processes are conducted in batch-type furnaces ensuring optimal process and lot control.
- Every ThermTech furnace is AMS 2750 certified, guaranteeing top-notch temperature uniformity during the hardening process.
Additional Services:
For those seeking a pristine finish post-normalizing, ThermTech provides several blasting services to eradicate any oxide or scale.
At ThermTech, our commitment is not just towards offering exceptional heat treatment solutions, but also towards empowering our clients with the knowledge and expertise that comes from years of industry leadership. Whatever your need, ThermTech stands ready to deliver with precision and excellence.
