Our Heat Treatment & Forging Services

From in-house normalizing to precision closed die forgings, MTS Forge delivers complete, material-qualified solutions for high-performance alloys.

Heat Treatment

Specialized in-house normalizing heat treatment for forged components, including nickel alloys like Inconel 600. The process refines grain structure, relieves internal stresses, and produces uniform mechanical properties across the entire part.

Closed Die Forgings

Precision closed die forgings in high-performance alloys, including Inconel 600, that reduce raw material consumption and machining costs while delivering consistent dimensional accuracy and superior metallurgical integrity.

Custom Forgings

Custom-forged Inconel 600 and specialty alloy components tailored to exact engineering specifications. MTS Forge combines advanced tooling design with decades of metallurgical know-how to meet the most demanding application requirements.

Rough Machining

In-house rough machining applied directly after forging to bring Inconel 600 components to near-net shape, removing flash and dimensional excess before heat treatment or final inspection — eliminating the need for a separate machining vendor.

Upset Forgings, Rings & Cylinders

Production of upset forgings, rings, and cylinders in Inconel 600 and nearly all available alloy grades, with maximum forging diameters up to 26 inches and individual piece weights up to 1,500 pounds.

Contour Forging

Contour forging services in specialty and high-performance alloys that showcase MTS Forge's ability to supply complex near-net shapes with minimal material waste across aerospace, defense, and energy applications.

Metallurgical Expertise

Precision Heat Treatment Engineered for Inconel 600 Performance

Inconel 600 is a solid-solution-strengthened nickel-chromium alloy that responds to heat treatment through controlled annealing and normalizing protocols rather than precipitation hardening. MTS Forge performs in-house normalizing by heating components above their upper critical temperature and allowing controlled cooling in still air, breaking up irregular grain structures formed during hot forging and producing a refined, uniform microstructure. The result is measurably improved tensile strength, enhanced ductility and toughness, and reliable machinability — properties that aerospace, defense, and nuclear procurement specifications mandate.

Frequently Asked Questions

What is the heat treatment of Inconel 600?

Inconel 600 is typically heat treated through annealing rather than precipitation hardening, as it is a solid-solution-strengthened alloy. The standard anneal involves heating to approximately 1700°F–2000°F (927°C–1093°C) followed by rapid cooling or air cooling. For forged components, normalizing — heating above the upper critical temperature and cooling in still air — is commonly applied to relieve forging stresses and refine grain structure, producing a uniform microstructure with consistent mechanical properties throughout the part.
