What are the top 10 Q690E carbon steel plate sheet hot rolled plates mills in Iran

At the same time of doing well in Q690E carbon steel plate sheet production and operation, Yunnan company focused on completing the four phases of technical transformation construction projects, realizing industrial upgrading, improving equipment level, and laying a good foundation for the future development of the company. In the Q690E carbon steel plate sheet technological transformation project, pollution control facilities have been built synchronously, and a large number of comprehensive utilization projects, such as comprehensive sewage treatment and recycling project, blast furnace gas waste heat and residual pressure power generation, have been invested and constructed.

45MnB characteristics and applications: alloy structural steel has good hardenability, the critical hardenable diameter in oil reaches 17 ~ 31mm. The machinability of steel Q690E carbon steel plate sheet is good, the forging and heat treatment process performance is also good, the tendency of grain growth, oxidation, decarburization and heat treatment deformation is also small when heated. 45MnB steel is mainly used for gears on machine tools, spindles of drilling machines, turning shafts and cams of tractors.

Flat steel is a kind of steel with rectangular cross-section and blunt edges at the edges and corners. It is usually 12-300 mm wide and 3-60 mm thick. Compared with Q690E carbon steel plate sheet ordinary steel plate, the utilization rate of flat steel is increased by one to five percentage points. Moreover, flat steel can be produced with fixed thickness, width and length according to the user's requirements, which saves the cutting process for users, reduces the consumption of labor and materials, and also reduces the processing loss of raw materials, saving time, labor and material.

A small amount of Nb is sufficient to obtain excellent comprehensive properties of Q690E carbon steel plate sheet etc. steel material, because at low Nb concentration, the yield strength of steel material increases faster and is proportional to the concentration, but when the Nb content is greater than 0.03%, the strengthening effect begins to decrease. Studies have shown that when the Nb content is greater than 0.06%, excess Nb will no longer strengthen the steel material.
