Q345B carbon steel plate sheet special shaped plate

We are a professional Q345B carbon steel plate sheet steel raw material supplier with a history of 17 years. After years of development, the company's steel plates and coils are widely used in construction, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and other fields around the world. With good product Q345B carbon steel plate sheet quality, we have solid project cooperation with foreign governments or leading enterprises such as Egypt, Bangladesh, Myanmar, Thailand, Philippines, Vietnam, Venezuela, Peru, Mexico, the United States, Portugal, Russia, Iran, Iraq, Pakistan, etc.

SA516GR70N steel is a standardized medium and low temperature pressure vessel. The overall performance is improved and the Q345B carbon steel plate sheet product price is higher. The steel plate has the following characteristics: good impact resistance, low temperature deformation, good welding performance, good fatigue resistance, good anti-laminar cracking performance, low carbon equivalent, and strong resistance to sulfur and hydrogen. The products available for steel plates with a thickness of less than 200mm.

A572 Grade 50 hot rolled plates and sheets are exhibiting features such as high tensile strength, oxidation and corrosion resistance, working ability, durability, long-lastingness, and formability. All these are responsible for making it the best selection. In addition to that these HR plates Q345B carbon steel plate sheet maintain the properties for a longer duration at the high temperature with no harm. The documents are also offered by us to our clients like MTC as per EN10204/3.1b, radiography test report, packaging list, size and quantity inspection and so on to give surety that only premium quality of the product is supplied to them.

Processing performance of quenched and tempered steel: Q345B carbon steel plate sheet plate can be used for cold working, bending and cutting. When the gas is cut off, cracks will not occur even without preheating. When preheating processing, quenched and tempered steel needs to be processed below the tempering temperature. Superb wear and corrosion resistance: Because it contains alloy elements such as copper and chromium, it has good corrosion resistance, higher hardness, and good wear resistance compared with ordinary steel.

What is the difference between Q345B steel and Q345A steel? Q345B carbon steel plate sheet, 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.

As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality Q345B carbon steel plate sheet products and more satisfactory services. Customer demand is our pursuit, and win customer satisfaction with quality. BBN after-sales team is responsible to solve the problem of technical support and quality, service complaints.
