FB2 steel thickness range materials supplier with rice experience

In recent years, in line with the development trend of iron and FB2 steel thickness range steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which FB2 steel thickness range are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

Composite steel plate is a composite steel plate which is made of carbon steel or low alloy steel as the base material and coated with stainless steel, titanium alloy, FB2 steel thickness range and other composite materials, or sandwiched with other metal or non-metal materials between two layers of steel and processed by pressure or blasting. It is mainly used to make chemical equipment and chemical storage tank, or obtain special functions such as shock absorption. The manufacturing methods of composite steel plate include rolling method and explosion method, but most of them are rolling method.

Main characteristics of 12Cr1MoV Steel: compared with 12CrMoV steel, 12Cr1MoV steel has higher oxidation resistance and thermal strength. The creep limit of 12Cr1MoV steel is very close to the endurance strength value, and it has high plasticity under the condition of endurance tension; the processability and weldability of 12Cr1MoV steel are good, but it needs to be preheated to 300 ℃ before welding, and stress removal treatment after welding. 12Cr1MoV steel is widely used in Superheater, header and main steam pipe of high pressure, ultra-high pressure and subcritical utility boiler.

X-rays or γ-rays are projected on the surface of the steel plate, and rubber can be placed on the other side of the steel plate. Since the radiation propagates through the steel plate and is absorbed, the intensity is different due to the presence or absence of defects, so the film can record the shape and position of the defects. This FB2 steel thickness range method is sensitive to the detection of common steel plate defects such as slag inclusions, porosity and pores. The disadvantage is that it is difficult to find the specific depth of the defect and it is not easy to find cracks.

What is the difference between Q345B steel and Q345A steel? FB2 steel thickness range, Q345B steel and Q345A steel have slight difference in chemical composition: Q345A steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.045, S ≤ 0.045, V 0.02 ~ 0.15; Q345B steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.040, S ≤ 0.040, V 0.02 ~ 0.15. The difference between Q345B steel and Q345A steel is mainly in A and B behind the steel grade, Q345A steel grade is not subject to impact; Q345B steel grade needs 20 ℃ room temperature impact test.

Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, FB2 steel thickness range sheet, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding. Through continuous technological innovation and after-sales service optimization, the company has its own world on the domestic and international steel industry stage!
