Comparison Of Steel Type Of AST, JSI, DIN

The world’s largest steel producing countries and regions are China, Japan, the United States, Russia, South Korea, Germany, Ukraine, India, Brazil, Italy, of which China is the top, is the world’s largest steel producer. Because of its huge production capacity, inevitably become a steel exporter, which also led to some anti-dumping measures in many countries around the world. Because of the characteristics of Chinese steel – high quality and low price, making it the world’s best-selling steel, and maintain the monopoly of the steel market.

Each country has its own steel industrial standards, such as AST of the United States, Japan’s JIS, Germany’s DIN, BS of the British and China’s GB. Although the element content and performance of steel is similar, because the standard is not common, the actual use of the standard often encounters the problem of substitution. As the steel mill’s customers mainly from the domestic, so under normal circumstances, the steel production are GB steel. Of course, China’s steel mills can also manufacture in accordance with standards such as AST or DIN, and only when the customer’s order quantity reaches the minimum order requirement, the mills are in accordance with the corresponding standards for production, in general, The amount is 2000-4000 tons.

And in many cases, the customer’s order quantity does not meet the minimum requirements, they usually need to choose the appropriate national standard to replace. Because of the difference between GB steel with AST, DIN, JIS is not large, usually only small differences in size. Here we sorted out the common standard of different steel code, we hope to help.
