Steel Heat Treatment Is Worth To Many Industries
Steels can be heat treated to produce a wide range of microstructures and properties. Typically, heat treatment utilizes phase transitions to alter the microstructure of a solid state during heating and cooling.
What is heat treatment of steel?
Heat Treatment Instructions
In heat treatment, processing is usually heat treatment, which just changes the structure of steel. During the thermomechanical treatment of steel, the shape and structure of steel components will also change. During the thermochemical process of steel, the surface chemistry and structure of the steel will change. Ton
The thermomechanical treatment process is also an important treatment method for steel heat treatment, and these methods are being considered in the field of heat treatment. The heat treatment process requires strict control of all factors that affect the heating and cooling of steel. The atmosphere of the heating furnace also affects the state of the steel being heat treated.
Improve metal properties
Heat treatment is a heat treatment process that achieves three major improvements in the material properties of metal castings:
- Improve mechanical properties
- Reduce residual stress
- Enhanced corrosion resistance
3 factors affect the heating rate
The heating rate of a part depends on several factors. These factors are as follows.
(i) the thermal conductivity of the steel,
(ii) the condition of the steel,
(iii) Dimensions and cross-sections of the steel.
Why do we need to heat treat steel?
As mentioned above, heat treatment is used to achieve various desired results in metal castings. Heat treatment can also be designed to reduce hydrogen content, simulate service conditions, restore mechanical properties, and reduce stress after project welding. These different results are achieved by different heat treatment processes. The main goal of heat treating is to meet customer specifications and industry standards.
6 Ways to Ensure Heat Treating Safety
- Workers must wear heat-resistant clothing. Such as protective clothing, gloves, safety glasses and a mask to prevent exposure to hot oil, which can burn the skin.
- Before ignition, ensure that safety measures such as air switch, exhaust fan, and automatic shut-off valve are in place.
- Before starting the heat treatment operation, please make sure that the quenching oil is not polluted by water. Contact of water with quench oil may cause an explosion
- Ensure that there is adequate ventilation in the quench area to maintain the required oil mist levels.
- When lighting the stove, follow the instructions provided by the manufacturer.
- Make sure the quench solution is mixed with a suitable bactericide or bacteriostat.
