Heat Treatment consisting of austenetizing (the point at which the structure of the ferrous product becomes austenitic) followed by air cooling.

Stress Relieving of Flame Cut Profiles up to 6m Diameter. Aluminium, Stainless and Mild Steels.

Heat Treatment consisting of Heating and Soaking at a suitable temperature followed by cooling under conditions such that, after return to ambient temperature, the metal will be in a structural state closer to that of equilibrium Thermofax Ltd process to the following technical conditions: Full Annealing: Performed at a temperature above the Ac3 point. Inter Critical Annealing: Performed at a temperature between the Ac1 and Ac3 points. Isothernal Annealing: Annealing involoving Austenetizing followed by cooling which is interrupted by soaking for a period at a temperature at which the transformation from austenite into ferrite and pearlite, or cementite and pearlite is complete. Solution Annealing: Applied to austenitic steels. Consisting of heating to a high temperature followed by cooling sufficiently rapidly to preserve a homogenous austenitic structure on return to ambient temperatures. Spherodize Annealing: Prolonged holding at a temperature in the region of the Ac1 point, oscillating around this temperature in order to bring about the spherodization of the precipitated carbides. Sub Critical Annealing: Annealing at a temperature slightly below the Ac1 point.
