On the big stage of global steel trade, steel standards are like precise rulers, measuring the quality and specifications of products. Steel standards in different countries and regions are different, just like different styles of music, each playing a unique melody. For companies involved in international steel trade, accurately mastering the material grade comparison between these standards is the key to opening the door to successful trade. It can not only ensure that the steel that meets the needs is purchased, but also avoid various disputes caused by misunderstanding of standards in sales, and reduce trade risks. Today, we will focus on Russian standard steel and Chinese standard steel, deeply analyze the material grade comparison between them, and explore the mystery.
Interpretation of Chinese standard steel material grade
China's steel standard system is like a magnificent building, rigorous and systematic. In this system, common carbon structural steel is represented by grades such as Q195, Q215, Q235, and Q275. "Q" represents yield strength, and the number is the value of yield strength in megapascals. Taking Q235 as an example, it has moderate carbon content, good comprehensive performance, coordinated strength, plasticity and welding performance, and is widely used in construction and engineering structures, such as building plant frames, high-voltage transmission towers, etc.
Low-alloy high-strength steel also plays a key role in many fields, such as Q345, Q390 and other grades. Q345 steel has excellent comprehensive mechanical properties, welding properties, hot and cold processing properties and corrosion resistance. C, D and E grade Q345 steel has good low-temperature toughness and is often used in high-load welded structural parts such as ships, boilers and pressure vessels. Its quality grade ranges from A to E. As the impurity content decreases, the impact toughness increases, and it can adapt to more stringent use environments.
Analysis of Russian standard steel material grades
Russia's steel standard system is centered on the GOST standard, like a unique puzzle with its own construction logic. In its carbon structural steel series, steel grades such as CT3 are more common. This type of steel has a moderate carbon content and is widely used in machinery manufacturing, construction and other fields, such as the manufacture of some small mechanical parts, and the construction of beams and columns in ordinary building structures.
In terms of low-alloy high-strength steel, grades such as 09G2С perform outstandingly. It has a reasonable ratio of alloy elements, high strength and good welding performance, and is often used to manufacture large structural parts such as bridges and ships. In bridge construction, it can withstand huge loads and the test of the natural environment to ensure the stability of the bridge. In Russia's oil and gas pipeline laying projects, steel that meets Russian standards can often be seen. With excellent corrosion resistance and high strength, they adapt to harsh geological and climatic conditions and ensure the safety of energy transportation. Compared with Chinese standards, Russian standard steels have differences in the provisions and performance requirements of certain element contents, and this difference also leads to their own characteristics in different application scenarios.
Comparison details of steel material grades between China and Russia
In order to more intuitively present the material grade comparison relationship between Russian standard steel and Chinese standard steel, the following is a comparison chart of common steels:
Take pipeline steel as an example. In the Sino-Russian cooperative energy pipeline project, if the Russian side uses K48 steel, the Chinese side can use L360 steel instead. The two have similar performances in strength and toughness, and can meet the requirements of the pipeline to withstand internal pressure and external environment. In the field of construction, when Russian construction projects use C345 steel, China's Q345 steel can also do a good job with similar mechanical properties and good weldability to ensure the stability of the building structure. This material grade comparison is crucial in actual trade and engineering. It can help companies accurately match needs when purchasing and using steel, reasonably select steel, reduce costs, promote the smooth development of Sino-Russian steel trade, and provide strong support for the successful implementation of various engineering projects.
