Metal Heat Treatment Services
Heat treatment is one of the most effective ways to strengthen and refine metal parts. At Midwest Metal Products, we provide a full range of metal heat treatment services that help improve hardness, wear resistance, toughness, and overall performance. Because our company is run by metallurgists, every process is backed by deep technical knowledge and years of hands-on experience. Whether you need a surface-hardened gear, a fully hardened shaft, or a part stress-relieved for machining, we have the equipment and skill to deliver consistent results.
Learn more about what MMP can provide for you by checking out our heat treatment options below:
Case Hardening
Case hardening service is a heat treatment process that hardens steel alloys so that a substantially harder surface layer is created, leaving a softer interior. MMP specifically uses carburizing as our primary method of case hardening.
Through Hardening
Hardening heat treatment uses a rapid quench process in order to increase the hardness throughout steel alloy components. The purpose of this process is to increase the strength of the metal. Through hardening diffuses carbon throughout the entire section of steel, making it thoroughly hardened, as opposed to case hardening, which leaves a softer core.
Annealing
The heat treatment, annealing, is used to lower the hardness of metals and alter the physical properties of the casting being treated. MMP accomplishes this by heating metals at a suitable temperature and then subsequently lowering the metal to a second temperature, resulting in the desired effect.
Normalizing
Normalizing involves heating an alloy to a temperature above the transformation range, followed by cooling in air to a temperature substantially below the transformation range. This heat treatment achieves grain refinement and improved homogenization.
Tempering
Tempering is a heat treatment that reheats already hardened steel to a temperature below the critical range in order to soften it and improve impact strength.
Blue Coating
Blue coating is a heat treatment that involves protecting metals against rust. MMP accomplishes this by immersing steel parts in a special chemical solution that is then heated to an acceptable temperature.
Quenching
When it comes to heat treatment, MMP offers air quenching, oil quenching, and water quenching services. Having these options to choose from is vital because no two projects are the same, and each finishing project must meet your specific needs.
Industries Served
Our metal heat treatment services are used across a wide range of industries. Companies in construction, energy, mining, food processing, waste-to-energy, and trenchless construction rely on our processes to keep their equipment running longer and more reliably. Heat treatment is not a one-size-fits-all solution, so we adjust every process to match the material, design, and end-use of the component.
Why Choose Midwest Metal Products?
Working with us means you get more than just processing, you get practical guidance from a team that understands metals at their core. We offer heat treatment for parts we manufacture, and we also accept customer-supplied castings. That flexibility allows you to get the exact service you need without unnecessary steps or delays. Our customers rely on us because we combine casting, machining, finishing, and heat treatment under one roof, saving time and simplifying the process.
