Heat Treating Market Growth Factors

Rapid expansion of the aerospace industry

The aerospace industry's rapid expansion is driving the global heat treating market. This is mainly due to the increasing popularity of air travel. Additionally, improved regional connectivity and modern infrastructure will benefit the aerospace sector. Various airlines have reserved new and used aircraft to meet the growing air travel demand.

Growing sales of vehicles worldwide

In order to enhance the efficient use of various components in the automotive industry, there is an increasing demand for heat treatment due to rising global vehicle sales. The heat-treating process is also used to enhance the thermomechanical behavior of alloys based on nickel-titanium (Ni-Ti). It helps improve the machinability and surface properties and increases metals' strength, hardness, and wear resistance. These alloys are widely used in the biomedical industry to make coils and treat cerebral aneurysms, which are localized dilations of the intracranial arteries. The top market players are also introducing a dependable, affordable, innovative system for automating the heat-treating process. It will have a drive circuit, a sensor, a control unit, and an algorithm that work together to speed up processing and reduce human error.

Heat Treating Market Restraining Factors

High installation costs and high energy consumption

A significant amount of energy is required for the heat treatment used in the metal industry, which restricts the market growth. Using machines with a low energy-efficiency ratio can be detrimental to the environment and reduce the overall effectiveness of a business's operations. Small and medium-sized businesses have obsoleted using outmoded technology and various procedures. In addition, the high installation costs associated with heat treating present a risk to the expansion of the market.
