JIS SM490YB plates Price in Germany

The toughness of steel such as JIS SM490YB plates is the ability of steel to absorb energy in the process of plastic deformation and fracture, and also the ability of steel to resist impact load. It is related to and different from the plasticity of steel. It is the comprehensive performance of strength and plasticity. The strength plasticity index of steel is obtained by static tensile test. When these indexes are used to bear the dynamic load structure, there are obvious limitations.

Welded pipe, also known as welded steel pipe, refers to the steel pipe made of steel plate or strip steel after crimping and forming, with a fixed length of 6 meters. The production process of welded steel pipe is simple, the production efficiency is high, the varieties and specifications are diversified, and the equipment investment is less, but the general strength is lower than that of seamless steel pipe. JIS SM490YB plates, Welded pipes have many uses and are almost ubiquitous in our lives. However, when choosing welded pipes, we must pay attention to performance and material characteristics.

General Administration of Customs: China's JIS SM490YB plates and so on steel export in December was 4.684 million tons. According to data released by the General Administration of Customs on Tuesday, China's steel imports in December 2019 were 1.483 million tons, and the total imports in 2019 were 12.304 million tons, down 6.5% from 1316.6 in 2018. China's steel export in December 2019 was 4.684 million tons, and the annual export volume in 2019 was 64.293 million tons, 7.3% less than 69.335 million tons in 2018.

The production method of seamless steel pipe can be roughly divided into cross rolling method (menesmann method) and extrusion method. The cross rolling method (menesmann method) is to pierce the tube blank with the cross roll first, and then extend it with the rolling mill. This method is fast in production, but requires high machinability of tube blank. It is mainly suitable for producing carbon steel and low alloy steel tube, JIS SM490YB plates tube.
