As one of leaders of cast hi chrome heat treatment annealing industry, SBM always seeks innovation & excellence.
Heat Treatment of Cast Iron. The types of heat treatments for cast irons involve stress relief, annealing, normalizing and hardening (quench and temper). In each of these processes, it is important to understand the materials' response to its heat-treat process parameters (time, temperature and atmosphere). Stress Relief

This article is about the difference between heat treatment, annealing, and tempering. The article explains the effects of annealing and tempering on the physical properties of metals, such as ductility, strength, and brittleness. Also explained are the methods for annealing and tempering, as well as the microscopic changes that heat treating causes.

In the heat treatment of any white cast iron, care must be taken to avoid cracking by thermal shock; never place the castings in a hot furnace or otherwise subject them to rapid heating or cooling. The risk of cracking increases with the complexity of the casting shape and section thickness.

Carbon steel is a steel with carbon content from about 0.05% up to 2.1% by weight. The definition of carbon steel from the American Iron and Steel Institute (AISI) states: . no minimum content is specified or required for chromium, cobalt, molybdenum, nickel, niobium, titanium, tungsten, vanadium, zirconium, or any other element to be added to obtain a desired alloying effect;

The most common heat treatments applied to gray cast irons are stress relief because of nonuniform cooling of cast-ings and annealing to improve machinability. Subcritical heating is used for both. Stress relief is done at temperatures between 1020 and 1200˚F (550 and 650˚C) without sig-nificantly lowering strength and hardness.
