Effect of grain size on yield strength ratio of S355J2WP container steel

In order to further transform the operation mechanism, establish the operation concept of "market-oriented, customer-centric", strive to improve our core competitiveness and promote the rapid development of business; further strengthen customer marketing management, subdivide customer groups, establish a top-down, crisscross, hierarchical marketing mechanism of "everyone is a marketer", and provide for the needs of different levels of customers Corresponding services.

Compared with ordinary steel, structural steel has the following differences. First, the strength of structural steel is high, and its bearing capacity is far greater than that of ordinary steel. Second, the structural steel has low impurity and carbon content, uniform material and good performance. Third, structural steel has light weight and is suitable for building various frames. Fourth, it is convenient to build structural steel, which is conducive to construction efficiency and reduces construction time. In some construction fields, structural steel must be used. Where can we find S355J2WP container steel, structural steel suppliers?

Sprin steel refers to the special alloy steel used to manufacture all kinds of springs and other elastic elements. S355J2WP container steel, Spring steel has excellent comprehensive performance, good surface quality, accurate shape and size. The smelting of S355J2WP container steel, spring steel is very important. It is necessary to ensure excellent metallurgical quality, not only to ensure accurate chemical composition, but also to guarantee high purity. The content of sulfur, phosphorus, oxygen and nitrogen of spring steel should be low, and the uniformity and stability of spring steel should be good.

Three advantages of semi-endless rolling technology: 1. The limit specification of Q345B steel is expanded from 1.5 mm × 1300 mm to 1.5 mm × 1600 mm. 2. the semi-endless rolling technology can effectively reduce the fluctuations in the temperature, size, and shape control accuracy of the strip head and tail. 3. The different parts of the strip steel S355J2WP container steel produced by semi-endless rolling have uniform structure and mechanical properties, the yield strength fluctuation is less than 40 MPa, and the tensile strength fluctuation is less than 20 MPa.
