BBN steel 1/2 inch plate Q460D carbon steel plate sheet

As the thickness and hardness of Q460D carbon steel plate sheet increase, the tendency to crack at the cutting edge increases. In order to prevent the Q460D carbon steel plate sheet from cutting cracks, preheating should be carried out before Q460D carbon steel plate sheet cutting. Special attention should be paid to preheating to make the entire Q460D carbon steel plate sheet interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole Q460D carbon steel plate sheet cannot be preheated, the partial preheating method can be used instead.

Japan is a typical shipping first, and its raw materials are imported from Oceania, central and South America and other Asian countries. Most of the Q460D carbon steel plate sheet steel produced is exported to China and other Asian countries, and a small amount is exported to America. Shipping is the main way of its Q460D carbon steel plate sheet steel international transportation. According to the data, steel goods account for about 20% of the total sea freight in Japan. The domestic transportation of Japanese steel is mainly truck.

Strip steel is coiled and curved steel plate, which is different from common steel pipes and steel plates. Strip steel has obvious characteristics. First, it is thin and easy to curl, which is convenient for logistics and transportation. Second, the surface quality of Q460D carbon steel plate sheet, strip steel is good, the luster is bright and it has good flexibility. Third, the strip steel is easy to process. When you need to use it, you only need to straighten the bent part and you can directly process it. Fourth, the precision is high, and the strip steel can be made of plain carbon steel, carbon structure steel, spring steel, tool steel, stainless steel, etc.
