high quality A572 grade 65 carbon steel plate sheet exporter in Philippines

The basic phases of A572 grade 65 carbon steel plate sheet, 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 difference between application of 20# steel and Q345 steel. 20# steel is mainly used for making parts, which can be heat treated; Q345 steel is mainly used for making engineering structural parts, which is usually not heat treated. Q345 steel does not emphasize the composition, but its yield strength must be above 345mpa. Because the composition A572 grade 65 carbon steel plate sheet is not fixed, Q345 steel is difficult to heat treatment (the temperature and time control of heat treatment are related to the composition, and different components use different processes).

As of early November, China's pig iron output was 24.662 million tons. Although the output of pig iron has declined due to the suspension of production during the heating season, the rate of decline has been slow, still at a high level of over 24.5 million tons. This is 13.5% higher than the same period last year, which makes coke demand good, and the six rounds of increase have landed smoothly. Some areas such as Shandong even appear out of stock.
