Why q235b carbon steel plate is not easy to rust

The work performance of q235b carbon steel plate etc. steel material is mainly depended on its chemical composition, mechanical properties etc. parameters. The higher strength the steel has, the less quantity steel is needed to achieve same strong effect of the steel structure. However, the steel strength varies with the thickness. So please take steel thickness into consideration when evaluating the steel strength. For a certain steel, its strength also has something to do with the steel shape. For example, for a same steel grade, the steel strength is different for steel plates and pipes.

Through chemical composition analysis and simulation tests, it is found that A514 Gr Q steel plate is prone to cracks or decreased toughness during welding. ASTM A514 Gr Q steel plate is sensitive to cold cracking. In order to obtain good weld quality of q235b carbon steel plate, A514 Gr Q steel plate, it should be controlled from two aspects: (1) control the hardness value of HAZ; (2) control the residual diffusible hydrogen content.

The demand for iron ore from steel production has weakened. As China’s domestic market enters the off-season for consumption, the demand for iron ore from steel production will weaken to a certain extent. Affected by the fall and winter environmental protection production restrictions and the expected release of national scrap steel standards at the end of the year, the market outlook is expected to decline and prices will not rise Shows a volatile downward trend. Steel production declined slightly, and the demand for iron ore weakened.
