Our company's technical department is the core department of the whole company. There are a group of very professional technical personnel. They provide some architectural drawings according to the ideas of customers, and they are responsible for how to select the right materials. Including the evaluation of steel products such as multi steel plate, KA 32 crane vessel steel and steel pipe, grasp the whole production process, and strictly follow the production standards and customer quality requirements.
The steel used for bridge beams should also have excellent welding function and low notch sensitivity, high strength, toughness, and load and impact from rolling stock, as well as outstanding fatigue resistance, certain low temperature resistance, and atmospheric corrosion resistance. Q460qC steel plate delivery status: KA 32 crane vessel steel steel products are delivered in hot rolled, controlled rolled or normalized conditions.
According to GB 11251 technical standard, the chemical composition of 40Cr structural steel plate is as follow: Carbon content is 0.37-0.44 %, Silicon content is 0.17-0.37%, Manganese content is 0.50-0.80%, Chrome content is 0.80-1.10%. 40Cr steel is usually in shape of 40Cr steel plates and bars. KA 32 crane vessel steel, GB 11251 is for 40Cr structural steel plate with thickness range of 4-30mm. The tensile strength of 40Cr structural steel plate is 550-800Mpa. And its min. Elongation is 16%.
16MnDR steel plate is suitable for low temperature pressure vessels manufacturing. Grade 16Mn- indicates that the content of manganese (Mn) in the steel plate is relatively high, about 1% -1.6%, D- indicates low temperature, R- indicates pressure vessel. (Normally, when the content of a certain chemical element in steel is high, it needs to be marked in the material, for example, 1.6% manganese is written as 16Mn; certain elements such as Cr and Mo are higher, written as Cr1, Mo1, Such as 12Cr2Mo1R.) The normal delivery status is normalized delivery (Normalized).
Through the operation and management, brand advantage and improve pre-sales, sale of after-sales service, the efforts of the company into the industry leading enterprises.Relying on perfect quality management system, it has built up competition predominance and provided high quality, favorable price and perfect after service for customers.
For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate KA 32 crane vessel steel EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.
