What is H900 heat treatment

share with
 H900 solution treatment 17-4PH heat treatment method

17-4PH stainless steel hardness is not a simple physical concept, but 17-4PH material elasticity, plasticity, strength and toughness and other comprehensive indicators of mechanical properties,

It can be understood as the ability of 17-4PH material to resist elastic deformation, plastic deformation or failure, and can also be expressed as the ability of 17-4PH material to resist residual deformation and anti-failure.

In order to solve the problem of high cost, this paper presents a new construction method of large blind plate flange with simple and quick opening.The construction method of this paper introduces the structure, working steps and strength of the quick opening louver.Through the application in ninglan gas pipeline project, it is proved that the construction method of quick-opening blind hole improves the work efficiency, not only reduces the labor intensity of workers, but also reduces the cost.Stainless steel flange needs to do some preparation work before measurement, measurement, according to a certain way and method to determine different measurement methods, according to the specific situation, in order to ensure the accuracy of measurement.This paper presents a new construction method of large blind flange with simple and quick opening.The construction method of this paper introduces the structure, working steps and strength of the quick opening louver.Through the application in ninglan gas pipeline project, it is proved that the construction method of quick-opening blind hole improves the work efficiency and reduces the labor of workers.
