Heat Treatment Processes for Steel. Steels can be heat treated to produce a large range of microstructures and properties. Generally heat treatment uses phase transformation during heating and cooling to change the microstructure in a solid state. In heat treatment the processing is normally thermal and which modifies only the structure of

For carbon steels the stress relieve is typically around 580C 650C. Please note that stress release treatment at the higher end of the range could reduce the strength of TMCP steel. When post-weld heat treatment is required for TMCP steels it should preferably be done at the lower end of the range
Details
2 When the steel or any metal or alloy is heated as a separate operation of heat treatment to eliminate the residual stresses it is then called stress-relieving annealing. It is an annealing heat treatment to relieve the stresses induced in parts to reduce the chances of warpage during subsequent heat treatment with no chance of crack formation
Details
Although it is possible to heat treat welds the usual steel heat treatment cycle of austenitising cooling and tempering is generally impracticable. Distortion would be difficult and expensive to avoid and the weld metal would need to match the parent steel in composition particularly in carbon content as well as in properties and this will

2017-12-1This study was conducted in order to improve the mechanical properties of mild steel materials used as bolts and studs in coupling agricultural machinery following their frequent failure in service. Heat treatment at 900 0 C for four hours was done and six specimens of each were then quenched with different media used as the major source of strength enhancement
