Q345B carbon steel plate sheet Rolling

The company has a group of mature steel plate production and processing line construction and production management experience. In addition, the company has professional and technical personnel. BBN steel is a modern enterprise integrating scientific research and development, production processing, sales and service. The company now has finance department, production department, sales team, technical department, quality control department, logistics department and after-sales service team. At the same time, it also adheres to international standards and adheres to the international line.

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 Q345B 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).

Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the Q345B carbon steel plate sheet steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.

Q345B carbon steel plate sheet, Q345C low alloy structural steel plates stock and size available: 13*2600*3800, 11*2890*3950, 14*1580*4700, 15.1*1600*3300, 14*1820*3050, 32*3200*2950, 11*2530*2450, 14*2000*3400, 12.7*2320*13200, 14*2720*3300, 32*2000*2950, 11*2250*2700, 26*1830*3650, 6*1800*4000, 14*1850*3350, 36*1700*2800, 12*3770*6600, 32*1900*3500, 15*1050*10000, 12.5*2810*3750,33*1500*3200, 45*1800*2650, 65*1700*2600 (mm).

As steel transportation belongs to the transportation of major parts, so in the process of transportation, modern logistics technology, such as centralized transportation, information technology, is a bit out of place. Based on the current situation of China's Q345B carbon steel plate sheet steel transportation industry, highway transportation is a way of transportation that many enterprises often choose. Naturally, its business volume also accounts for more than 50% of the whole Q345B carbon steel plate sheet steel transportation industry.
