Solution Treating & Precipitation Hardening Service
Sometimes referred to as “age hardening,” precipitation hardening is a technique intended to increase a material’s resistance to increase strength. This process is used with many materials, including maraging steels, aluminum, some stainless steels, super alloys and more.
Solution treatment is a heat treating process that heats alloys to a specific temperature, sustaining that temperature long enough to cause one or more constituents to enter into a solid solution and then rapidly cooled to maintain the solution’s properties. Annealing is a commonly used type of solution treatment, sometimes referred to as solution annealing.
The Right Procedure for the Right Materials.
Solution treatment procedures vary depending on the material being treated. The main variance stems from the temperature the material is heated to and the rate at which it is quenched.
While common alloys including iron, nickel, cobalt and aluminum usually undergo some sort of solution treatment prior to manufacturing, other materials such as stainless steel requires vacuum furnaces for solution treatment because they remove gases from the atmosphere, which in turn prevents oxidation. Precipitation hardening is a common next step in the heat treating process, following an anneal and a quench.
Finding the Perfect Solution for Your Project.
There are many variances to address with solution treating. The main differences concern the temperature to which the material is heated, the amount of time it’s held at that temperature and the rate at which the material is cooled. All of these factors will vary based on the material that’s involved, so it’s important to choose an experienced heat treating partner you can rely on.
