q345b black steel market forecast this week

q345b black steel is easy to handle during work. Due to the ratio of different alloying elements, alloy steel is very expensive. Carbon steel is cheaper because it contains only trace amounts of other elements.

In 2019, the output of pig iron in the world was 1.265 billion tons, with China accounting for 64%; the overseas output accounted for 36% (460 million tons), ranking 86.982 million tons of EU 28 countries, 74.907 million tons of Japan, 74.099 million tons of India, 73.264 million tons of CIS, and q345b black steel 47.521 million tons of South Korea.

The company specializes in heavy plate cutting, carbon steel pplate processing, carbon plate welding processing and sales of wide and thick steel q345b black steel plates. It has high-quality CNC steel plate cutting and processing equipment, a professional technical personnel team, and supporting logistics distribution and after-sales service system. BBN company provides customers with solutions at low prices, high quality, and fast response service.

As soon as the grains of the steel sheet become coarse, the forming limit decreases. The total elongation, n value and r value in the mechanical properties of the q345b black steel steel plate have no direct influence on the forming limit of spinning. The steel plate used in the test is very thin (about 0.5mm), and the commonly used thickness q345b black steel steel plate (0.8-1.6mm) will definitely be much higher than the above limit.
