Martempering, also known as marquenching, is a heat treatment term used to describe a delayed quench from the austenitizing temperature. The point is to delay the cooling from where the transformation of the hardening constituent begins to form. By holding it there for a period of time it allows for temperature uniformity within the part being hardened. This process combines the hardening properties a traditional quench would produce while reducing distortion, the likelihood of cracking, and internal stresses associated with part geometry.
Martempering can be performed on any steel that is hardened via conventional quenching methods. Hardness & tensile strength can also be controlled by tempering after marquenching to meet your requirements.
Braddock Metallurgical can perform this process on parts up to 36” by 48” by 36” high while offering the same level of service, quality, and expertise our customers have become accustom to for over 60 years.
