Analysis and forecast of EN10083-3 alloy steel 1.7225 material price in China
With the development of API5L-B pipeline steel plate technology and the advancement of welded pipe forming and welding technology, the application scope of pipeline welded pipe is gradually expanding, especially the advantages of welded pipe in the range of large-diameter group spacing are more obvious. In 2004, the output of API5L-B (L245) seamless line pipe was about 400,000 tons. The steel grade includes X42-70, EN10083-3 alloy steel 1.7225 material, and the varieties include onshore line pipe and subsea line pipe.
The influence of thermal physical properties and mechanical properties of composite wear-resistant steel plate on laser bending is complex, which mainly involves the thermal expansion coefficient, specific heat capacity coefficient, thermal diffusion coefficient, yield limit, elastic modulus and hardening index. Under the same process conditions, the greater the specific heat and thermal conductivity of the composite EN10083-3 alloy steel 1.7225 material, wear-resistant steel plate, the less obvious the temperature gradient in the forming process, and the smaller the bending angle produced.
Plasma cutting has a wide range of applications. With different working gas, it can cut various kinds of metals that are difficulty to handle by oxygen cutting. Plasma cutting is fast and efficient when cutting metal with small thickness. The EN10083-3 alloy steel 1.7225 material cutting speed can reach more than 10m/min. Plasma cutting can get a clean, neat, non stick slag cutting surface, while the deformation and thermal effect of the incision are small, its hardness change is little, and the cutting quality is good.
