Does Carbon steel wedge anchor do heat treatment?

In order to make the blue white zinc plated wedge anchor more durable and strong, heat treatment is required:

The first step of the carbon steel wedge anchor zinc plated is quenching:

The carbon steel is heated to a temperature above the critical point AC3 or AC1, and the purpose of quenching is to greatly increase the hardness of the steel. In theory, any material can be quenched, but in fact, for example, low-carbon steel needs to be quenched at a cooling rate of 2000°C/s. At present, there is no such refrigerant in production that can achieve such a high cooling rate. Therefore, it is generally considered that low carbon steel cannot be quenched.

The first step of High quality zinc carbon steel wedge anchor is annealing:

The heat treatment process in which steel is heated to an appropriate temperature, kept for a certain period of time, and then slowly cooled is called annealing. The purpose of annealing is to refine crystal grains, homogenize the structure, reduce hardness, improve plasticity and eliminate internal stress.

The third step of carbon steel wedge anchor factory heat treatment is normalizing:

The heat treatment process of heating the steel to 30-50°C above the critical point AC3 or ACcm, holding it for a certain period of time, and cooling it in still air is called normalizing. Normalizing can refine the grains and improve the impact toughness and comprehensive mechanical properties of steel.

The fourth step of heat treatment for Stainless steel wedge anchor and carbon steel wedge anchor manufacturers is tempering:>

The heat treatment process of reheating the quenched steel to a temperature below the critical point AC1, holding it for a certain period of time, and then cooling it to room temperature in air or oil is called tempering. The purpose of tempering is to stabilize the organization, stabilize the performance and size of the parts in use; eliminate internal stress; improve plasticity and toughness.

According to the different heating temperature, tempering can be divided into high temperature tempering (above 400℃), medium temperature tempering (250~400℃) and low temperature tempering (150~250℃). For important welded structures, high temperature tempering is often used to eliminate the residual welding stress in the structure.

The heat treatment process of carbon steel wedge anchor quenching and high temperature tempering is called quenching and tempering treatment. After quenching and tempering, comprehensive mechanical properties with good strength, plasticity and toughness can be obtained.
Heat treatment can give full play to the potential of steel, improve the performance of the workpiece, reduce the weight of the workpiece, save materials, reduce costs, and extend the service life of the workpiece.
