Flame Hardeners (through its' associate companies) offer this range of treatments for castings, forgings, or wrought components in material ranging from plain carbon to stainless and high alloy steels, and irons up to 2.7m long x 1.5m diameter. Similar sizes are available for the heat treatment of non-ferrous alloys. With a wide variety of sizes and types of furnaces, (horizontal and vertical), we have the capability to suspend long, slender items vertically to minimize distortion arising from the treatment. Available atmospheres range from; air, products of combustion, controlled atmosphere, to vacuum, with available atmospheres dependant on the component material, size, shape and final requirements.

Annealing can be performed for a variety of reasons, such as reducing hardness, improving machinability, facilitating cold working, homogenising the material, obtaining a desired macro-and micro-structure, or specific mechanical properties, removing internal stresses, etc. Annealing thus covers a wide variety of treatments dependant on the material and the requirements, and can therefore vary from a low temperature sub-critical anneal, to a complex full anneal cycle.

Note. The terms normalizing, stress relief annealing, sub-critical annealing, full annealing, cycle annealing, isothermal annealing, interstage annealing, and process annealing, are often confused, and the Engineer should give careful consideration of the purpose of the treatment in order to decide which procedure to use.
