hot working meaning in Hindi

Examples

1. However, not all materials display well-defined peaks when tested under hot working conditions.
2. Swaging is usually a cold working process; however, it is sometimes done as a hot working process.
3. For these reasons the windows and doors were almost always kept shut, resulting in a very hot working environment.
4. "' Hot working "'refers to processes where metals are plastically deformed above their recrystallization temperature.
5. Unlike hot working, the inclusions and grains distort to follow the contour of the surface, resulting in anisotropic engineering properties.
6. Therefore the tooling temperature must be compromised; commonly, hot working tooling is heated to 500 850 �F ( 325 450 �C ).
7. The most important aspect of any hot working process is controlling the temperature of the workpiece . 90 % of the energy imparted into the workpiece is converted into heat.
8. Hot working of nitinol is relatively easy, but cold working is difficult because the enormous elasticity of the alloy increases die or roll contact, leading to tremendous frictional resistance and tool wear.
9. In a stress-strain curve, the onset of dynamic recrystallization can be recognized by a distinct peak in the flow stress in hot working data, due to the softening effect of recrystallization.
10. A53 pipe comes in three types and two grades, "'A53 Type F "', which is longitudinally furnace butt welded or continuous welded ( Grade A only ), "'A53 Type E "', which is longitudinally electric resistance welded ( Grades A and B ), and "'A53 Type S "', which is seamless pipe, produced by hot working, and possibly cold finishing, the steel ( Grades A and B ).
