q235b sheet hot rolled exported to Nigeria

The main difference between q235b sheet hot rolled, 45# steel plate and boiler steel plate is the difference of carbon content and impact toughness. 45# steel is a high-quality carbon structural steel, which is expressed by the number of ten thousand percent of the average carbon content. The 45# steel represents the high-quality carbon structural steel with 0.45 percent carbon content. The high-quality carbon structural steel contains less harmful impurity elements (S, P) and non-metallic inclusions, and has excellent plasticity, toughness and processing technology.

The toughness of steel such as q235b sheet hot rolled 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.

The "Plan" pointed out that by the end of December 2020, the steel production capacity in Tianjin will be controlled at about 15 million tons, and the steel production capacity in Hebei Province will be controlled within 200 million tons, and the elimination of the carbonization chamber with long furnace age and poor furnace condition will be accelerated. 4.3 Rice coke ovens promote the gradual withdrawal of independent coking companies. At present, there are 24 steel enterprises in Shanxi Province in need of transformation, of which 17 have been completed, and the remaining 7 enterprises are speeding up project-related finishing work.

At present, the q235b sheet hot rolled steel plate cutting is mostly by laser, is charged on time, such as an hour between 400 yuan to 1000 yuan. Of course, different regions, the price also has big difference. The price of steel plate cutting in the south is relatively high, and the north because of the former heavy industry is more developed, so the price of q235b sheet hot rolled cutting is relatively low. Of course, no matter what kind of laser cutting steel plate, its price float is also in this range, if the price is higher than this range, you need to choose carefully.
