Stainless steel is a leader in metal materials, it has many excellent properties, such as corrosion resistance, heat resistance, low temperature resistance, good processing properties, stainless steel appearance, has been widely and extensively used in various industrial and civil fields. It is a very good structural and functional material.
Stainless steel has been existenced for more than 90 years since its inception at the beginning of the last century. The invention of stainless steel is a great achievement in the history of metallurgy in the world. It not only lays the material foundation for the establishment, development, and scientific and technological progress of modern industry, but also expands the scope of civil use. The application has also significantly improved people’s quality of life.
Back in history, more than 1,000 years ago, iron pillars in ancient Hindu temples and iron people in front of ancient Chinese temples, etc., were exposed to wind, rain, and sunlight for exposure to selenium for years, but they were highly resistant to corrosion. Caused the attention of many scholars and experts. From 1820 to 1822, the British scholar F. M. Faraday first studied the problem of rusting of low-alloy steels as a subject. He was the founder of stainless steel research.
The development of stainless steel demand is closely related to people’s living standards. The experience of international stainless steel development shows that stainless steel consumption growth is 1.5 to 2 times GDP. Historically, the development of the military industry has led to the development of stainless steel. The rapid growth of civilian using and the expansion of the use of stainless steel have driven the rapid development of stainless steel. In our daily life, stainless steel can be seen everywhere from eating tableware to urban landscapes and building construction. Since most of the stainless steel daily products use sheets, the overall demand is mainly plate.
Stainless steel production has become more and more concentrated. From the current situation of stainless steel, it can be seen that stainless steel production is mainly concentrated in several countries and regions such as Belgium, Germany, Japan, and Taiwan Province of China.
