Problems solved by technology

[0002] my country has become a big country in the production and consumption of steel pipes, but there is a large gap between the level of equipment and product quality and that of advanced developed countries, especially the small-diameter seamless capillary stainless steel pipes have high technical content and are difficult to manufacture. For a long time, they have been monopolized by foreign countries. , mainly Japan, France, Germany and the United States, etc. my country basically relies on imports, but expensive raw materials and supporting import costs will largely restrict my country's productivity level and even affect the healthy development of the entire industry; , Due to the unreasonable composition and process, the seamless capillary stainless steel tube has poor oxidation resistance, low tensile strength and high yield strength, high surface roughness, and short service life.
