The automotive industry is one of the most utilized and emerging sectors today, where many different materials are manufactured. A modern automobile that is profoundly manufactured using a heat-treating process with components made of aluminum is observed to be much lighter than the components and the parts made of steel, which directly enhances and improves the fuel consumption efficiency of the automobile.

Increasing demand for energy-efficient products and new generations of electric vehicles creates demand for this market. The automotive industry has been witnessing increasing sales of efficient and electronic vehicles. Much of this can be credited to growing regulations, net-zero initiatives, and the ever-increasing number of EVs available to consumers.  Automobiles require heat-treated metals for thermal proofing and crash-proofing, which ensures the safety of drivers throughout the changing weather. Moreover, heat treatment helps build the vehicle brand's credibility, driving the global heat treating market.

Global auto sales recorded strong growth in 2023. According to IEA estimates, global car sales expanded at a robust rate of 10.8% year-on-year growth. Car sales recorded a double-digit growth rate in all three major geographical markets, rising +12.4% in the United States, +11.0% in China, and +13.7% in Europe, comprising the EU, UK, and EFTA markets. Moreover, China is at the forefront, with 60% of global electric car sales in 2022. U.S. and Europe, the second and third largest markets, witnessed strong growth, with sales increasing by 15% and 55% in 2022, respectively. Such factors are increasing the demand for heat treatment in the market.

Ambitious policy programs in major countries, such as the Fit for 55 package in the EU and the Inflation Reduction Act in the U.S., are expected to increase market share for electric vehicles further this decade and over the forecast period. By 2030, the average share of electric vehicles in total sales across the EU, China, and the U.S. is set to rise to around 60%.

Increasing Demand for Various Industrial Equipment and Modern Machines Augments Demand for Heat Treating Processes

Industrialization is mainly based on the ownership of production and product technologies. Accordingly, heat treatment drives technological processes in several medium and high-technology industries, primarily the machine industry, white appliances, energy equipment, healthcare equipment, rail systems, shipbuilding, electrical appliances, electronics, and others. The heat treatment market applies heat treatment to metal, composite, and ceramic material inputs used by the abovementioned industries, among others. This treatment makes almost all industries as crucial as other manufacturing equipment and machines. Thus, it performs a critical function in the development and industrialization of different sectors.

Numerous progress in the heat treatment industry resulted in more robust, long-lasting, smooth-surfaced, easy-to-shape, flexible, and durable inputs. Therefore, heat treatment industries and production technologies are available in all industrialized countries, and the heat treatment industry is a precondition of industrialization. For instance, in 2023, to engage the rapidly increasing interest in compact track loaders (CTLs) in North America, Dana is expanding its annual production of Spicer Torque-Hub track drives by almost three times its previous production at the manufacturing hub in Lafayette. Spicer Torque-Hub drives for CTLs offer an output torque from 5,000 to 17,000 Nm, with increased productivity and maximized motor displacements in a compact package.

RESTRAINING FACTORS

Stringent Environmental Regulations on Fuel-Based Furnaces Hampers Market Growth

Heat treatment is a capital-intensive and energy-intensive market since it uses industrial and large-scale furnaces and equipment with high operating costs. As a result, the heat treatment market is a deciding factor in the cost-effectiveness and competitive strength of several industries, such as automobile, aerospace, construction, machine construction, and others. The commercial heat treating process is capital, labor, and energy-intensive, as the primary input of the heat treatment industry is energy, which accounts for a sizable portion of production costs.

Moreover, the commercial heat treatment market has a high level of environmental impact, which requires a high level of environmental sensitivity regulations. The environmental effects of heat treatment are categorized under water and energy consumption, use of chemicals, and waste output. For this reason, the heat treatment industry is positioned to be subject to the regulations set forth by the EU Green Deal. Generally, heat treatment generates substances that are more likely to be toxic compared to their ordinary waste components. Harmful toxins include dioxins, furans, and dangerous gases, such as mercury and cadmium. Small and medium-scale players have become obsolete using outdated technology and various procedures. Thus, all these factors are restraining the market growth. Worldwide attention has been emphasized on environmental issues, and global warming has been the central theme of the recent international summits. Utilizing low-energy efficiency machines harms the environment and lowers the overall effectiveness of business operations in different industrial sectors. Thus, these factors are hampering the market.
