BEBON Iron & Steel has fully passed the ISO9001 quality system certification, marine steel has passed 9 countries' classification societies, and construction steel has obtained the CE Lloyd's CE Mark certification. The main body of A573 Grade 70 plate steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main A573 Grade 70 plate production processes and technical equipment of the enterprise have reached the international advanced level, the comprehensive competitiveness has entered the international advanced ranks, and the international influence has been significantly enhanced.

Our main specifications of medium and heavy plates are thickness 6.0-180mm and width 1400-2700mm. In addition, the ship steel plate has been approved by the factories of the eight-nation classification society such as CCS, ABS, BV, LR, GL, NK, KR, and DNV. Our A573 Grade 70 plate, medium and heavy plates are widely used in manufacturing, logistics, and automotive industries such as construction machinery, mold processing, ships, bridges, high-rise buildings, pipeline transportation, automobile girders, automobile bridge shells, and pressure vessels.

The advantages of A573 Grade 70 plate, carbon steel: First of all, the price of carbon steel is low. Compared with stainless steel, galvanized steel, alloy steel, etc., the carbon steel has a great advantage in price. It is a good choice for manufacturers and merchants such as construction sites that use building materials in large quantities. Secondly, the carbon steel is easy to process. In the early days, steelmaking technology was underdeveloped. It was very difficult to manufacture high-precision steel, and carbon steel is widely used.

As A573 Grade 70 plate, alloy 400 is a kind of metal with good corrosion resistance, it shows good uniform corrosion resistance in the marine atmosphere. This is because alloy 400 can form a very thin and tough protective film. Uniform corrosion is one of the easiest forms of corrosion to deal with, because engineers can quantitatively determine the corrosion rate of metals and accurately predict the service life of metals.

A573 Grade 70 plate, No.45 seamless pipe belongs to high quality carbon structural steel. The carbon (C) content of No.45 seamless pipe is 0.42 ~ 0.50%, Si content is 0.17 ~ 0.37%, Mn content is 0.50 ~ 0.80%, Cr content is ≤ 0.25%, Ni content is ≤ 0.30%, Cu content is ≤ 0.25%. The tensile strength, yield strength, elongation, reduction of area and impact energy of No.45 seamless pipe are 600 MPa, 355 MPa, 16% and 40% respectively. No.45 seamless pipe is used to manufacture high strength moving parts.

BBN company is an industry leading steel service center that supplies a full line of hot rolled steel plate in a variety of sizes, grades and finishes. Hot rolled steel is an economical option that offers reliable performance and versatility. In the A573 Grade 70 plate hot rolled process, high temperature is used to heat the steel above its recrystallization point. In this state it becomes more malleable, allowing it to be easily formed into a variety of shapes. If you are interested in A36 hot rolled plates price, welcome to come and visit us.
