09cupcrni-a steel demand, Large diameter spiral steel pipe refers to the relatively large diameter spiral steel pipe, which is generally required to be more than 1000mm. The manufacturing process of large-diameter spiral steel pipe: first, the steel strip is bent into shape, and then welded together to make a large-diameter spiral steel pipe of specified size. After being processed into a pipe, hydrostatic test, bending, flattening and other tests shall be carried out, and the internal steel support of large-diameter spiral steel pipe can be made according to customer requirements.

High strength steel is a kind of steel often used in engineering construction. With the improvement of technical level, the research and development of high strength steel in China has made remarkable achievements. The application of high strength steel 09cupcrni-a steel demand in the construction field can reduce the steel consumption and building volume, and improve the building weight. That is one of the important reason why the high strength steel is so warmly welcomed nowadays.

The basic phases of 09cupcrni-a steel demand, structural steel in the annealed state are ferrite and carbide. The alloy elements are dissolved in ferrite to form alloy ferrite, which depends on solid solution strengthening to increase strength and hardness, but at the same time reduce plasticity and toughness. The addition of alloying elements reduces the carbon content of the eutectoid point, which increases the proportion of pearlite in the structure and reduces the distance of the pearlite layer. This also increases the strength of the steel and reduces the plasticity.

The S355 steel material itself is divided into many grades, so it cannot be said that S355 is equivalent to which grade of the national standard Q345, 09cupcrni-a steel demand. In engineering, usually S355JR steel is equivalent to Q345B steel, S355J0 steel is equivalent to Q345C steel, S355J2 steel is equivalent to Q345D steel, S355N steel is equivalent to Q345D steel, and S355NL steel is equivalent to Q345E steel.
