China Standard Steel Number System
As a leading global provider of steel products, steel number systems are used to classify and designate different types of steel. In China, a specific set of conventions exist for forming steel numbers. The Standardization Administration of China (SAC) uses an organized system to abbreviate and categorize steel using numbers. This article will provide an overview of China’s steel number system.
China’s steel number system is heavily influenced by its tradition of metallurgy and its frequent use of written characters. It begins with the use of designated numbers to represent the families of steel. For example, 15 represents Low Carbon Steel, 20 is for Structural Carbon Steel, and 30 is for High-Strength Low-Alloy Steel. This is followed by two or three numerical characters, which serve as an indication of the type of steel. After this are two or three letters assigned to the specific grade of steel. Finally, two numerical characters are assigned to describe the properties of the steel.
Furthermore, the Chinese steel number system allows for two different levels of classification for each kind of steel. Category I is for the generic form of the steel, which is commonly used for general fabrication and structural applications. Category II is a more specific form, which is typically customized for use in specific industries such as automotive, aerospace, and energy.
Additionally, bar codes are often used in connection with the Chinese steel number system. These bar codes allow manufacturers and fabricators to differentiate the products and track inventory. They are also used for cost optimization and quality control.
Finally, the Chinese steel number system is continuously evolving. As steel structures become more complex and industry standards change, the Standardization Administration of China is continually adding numbers to their system to keep up with market demands.
In conclusion, the Chinese steel number system provides a comprehensive and easily identifiable system for categorizing and labeling steel products. It is designed to enable producers and consumers to easily locate the exact grade of steel they are looking for. This system is not only beneficial for China, but it is also beneficial for commercial partners, as it helps eliminate confusion that can occur when dealing with different types of steel.
