Capabilities
Thermal Treatments
An integral part of our supply chain and technical service for every order size.
Our premier thermal treatment capabilities provide a diverse range of processing options to meet demanding strength and hardness requirements – regardless of order size. Metallus has both batch and continuous heat treat assets, heating via both gas-fired furnaces and induction, and maintain strict auditing practices and calibrations in accordance with industry standards like AMS 2750. Our metallurgical experts continuously evolve these capabilities and broaden our sophistication in custom thermal treat offerings so customers can rely on innovative product designs and proven quality.
We meet our customers’ needs through our high-quality steel bars, tubes, and billets, to which we can apply value-added services. Our approach to manufacturing integrates our melting, rolling, piercing, and finishing operations, ensuring a complete chemistry from start to finish. Our in-house lab tests samples from each batch using our own equipment to verify compliance and alignment with customer specifications.
Metallus has the capabilities to meet tough mechanical properties and achieve specific hardness or microstructure requirements for our customers’ projects. Benefits of our value-added thermal treatment capabilities include:
- Precisely controlled hardness and strength properties
- Improved ductility and toughness
- Anneal for subsequent forging or machining operations
- Relieved stresses caused by cold straightening
- Development of low-alloy customized grades for unique applications
Thermal Treatment Capabilities
Quench-and-temper
The quench-and-temper processes heats steel uniformly to a temperature above a critical range and cools it rapidly in a liquid medium. This treatment helps achieve specific levels of strength and toughness to meet the customer requirements.
Stress Relieve and Temper
Stress relieve helps minimize distortion for machining, while tempering relieves stresses and softens the product prior to cold working.
Anneal
Anneal is heating uniformly to a temperature within or above the critical range and cooling at a controlled rate to a temperature under the critical range. We use this treatment to produce a definite microstructure, usually one designed for the best machinability and ductility. We also use anneal to remove stresses, induce softness, and alter toughness or other mechanical properties.
Spheroidize Anneal
Spheroidize anneal uses a long heating cycle to produce carbide microstructures best for machinability and subsequent processing steps.
Normalize
In the normalizing process, we heat steel uniformly to a temperature at least 99° F (37° C) above the critical range and cool in air to room temperature. This treatment produces a recrystallization and refinement of the grain structure, giving the product uniformity in hardness and structure.

Lower-cost, corrosion-resistance solution for offshore wells: 4130ModSS
In partnership with a large oil and gas distributor, we developed a lower-cost alloy that would meet corrosion-resistance standards for offshore wells in sour service environments. We tested the grades in a lab environment to very specific customer requirements in accordance to NACE MR0175 standards, and partnered with a distributor to provide this comprehensive solution for applications in wells off the coast of Louisiana. As a result of this collaboration, we developed – and currently offer as part of our portfolio – steel grade 4130ModSS.
