Silicon nitride ceramic materials have excellent thermal stability, high oxidation resistance and high dimensional accuracy. Since silicon nitride is a covalent compound with high bond strength and can form an oxide protective film in air, it also has good chemical stability. It is not oxidized below 1200 ° C, and a protective film is formed at 1200 to 1600 ° C to prevent further. It is oxidized and is not wetted or corroded by many kinds of molten metals or alloys such as aluminum, lead, tin, silver, brass, nickel, etc., but can be corroded by molten materials such as magnesium, nichrome, and stainless steel.

Viewing the Development of China's Forging Industry from the "Quality Forging Award"
Since 2004, the China Forging Association has been hosting the annual China International Metal Forming Exhibition and Conference, showcasing the production capacity of enterprises and industries while keeping pace with the evolving trends in the forging sector. A key part of this event is the selection of the "Shengong Award" (also known as the "Quality Forging Award"), which recognizes outstanding and innovative forged products that drive industry development. On September 27, 2013, the awards ceremony and exhibition took place in Shanghai, highlighting a growing trend in the quality and diversity of Chinese forging products.
The forging exhibition serves as a reflection of the rapid development of China's forging industry. Since the reform and opening-up era, especially during the "Eleventh Five-Year Plan" period, the industry experienced significant growth due to increased demand from downstream sectors such as automobiles, construction machinery, agriculture, railways, wind power, and nuclear energy. The localization rate of forgings rose, and international markets began sourcing components from China, creating new opportunities for domestic manufacturers.
As market demand surged, the number of die-forged products increased dramatically—from over 1 million tons in 2002 to 6.9 million tons by 2010. This growth helped forging stand out as a key industrial segment. In response to rising demand, many traditional forging companies expanded their operations, while new players entered the market, contributing to a more competitive and dynamic industry landscape.
However, the forging industry has also faced challenges, such as the global economic crisis in 2008, which led to a sharp decline in orders. The government’s 4 trillion yuan revitalization plan helped stabilize the economy, leading to recovery in the forging sector. Over the years, the number of forging parts exhibited at the event fluctuated, reflecting broader market conditions and policy changes.
The industry has undergone significant transformation, with many companies moving towards "integration," extending their supply chains to ensure stability and efficiency. Companies like Tianrun Crankshaft and Guilin Fuda have invested heavily in advanced equipment to meet growing demands and improve product quality.
Energy saving and emission reduction have become central themes in recent exhibitions. Traditional forging hammers are being replaced by more efficient and environmentally friendly technologies, such as electro-hydraulic hammers and high-energy electric screw presses. These innovations not only reduce energy consumption but also improve product precision and material utilization.
Moreover, the adoption of new technologies and processes has significantly enhanced the competitiveness of Chinese forging products. Companies like FAW Barrett Forging, Dongfeng Forging, and Jiangsu Senwei Precision Forging have introduced advanced manufacturing techniques, producing high-quality components that match or exceed international standards.
In 2013, the exhibition witnessed an impressive variety of products, demonstrating the maturity and innovation of China’s forging industry. As the industry continues to evolve, it is clear that forging will remain a vital component of China’s manufacturing sector, driven by technological advancement, market demand, and strategic policy support.
