Research and development of stainless steel precision casting

Stainless steel precision casting can be traced back to the 1930s and 40s of the last century, the United States early used stainless steel precision casting method to cast the turbine blade in the aeronautical engine that was leading in science and technology at that time, and the finished product was praised by all aspects, so that this method has been promoted.

 

China's research and development and use of stainless steel precision casting is after the founding of new China, with the development of China's national defense industry, Liaoning, Guizhou, Beijing, Shaanxi, Hunan and other places have opened stainless steel precision casting research institutes or foundries. However, objectively speaking, China's stainless steel precision casting industry is still in the development stage, and can not meet the development needs of China's aerospace, national defense industry and other industries.
