A588 Grade B steel bars I beams

Q355NHB steel plate is atmospheric corrosion-resistant steel plate, also known as weather-resistant steel plate. It is a low alloy steel series between general steel and stainless steel. Weather-resistant steel is made of ordinary carbon steel with a few corrosion-resistant elements such as copper and nickel. A588 Grade B steel bars, Q355NHB steel sheet is featured by good toughness, plastic extension, forming, welding and cutting, abrasion, high temperature, fatigue resistance, etc.We are a professional A588 Grade B steel bars 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 A588 Grade B steel bars 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.The allowable working temperature of boiler steel plate is generally below 475 ℃, which can't meet the needs of high temperature working condition. Chromium molybdenum steel is one of the common steels for A588 Grade B steel bars pressure vessels, which is widely used in various hydrogenation units and reforming units in oil refining and chemical industry. Therefore, on the basis of common A588 Grade B steel bars carbon steel, alloy elements such as Cr Mo V are added, which has excellent hydrogen corrosion resistance and good high temperature strength, It is the material of high temperature and high pressure vessel shell and head,A588 Grade B steel bars., EN 10025 E355 steel plate / sheet is suitable for general building steel. Chemical composition and mechanical properties of EN 10025 E355 steel. EN 10025 E355 steel conforms to EN 10025 standard, equivalent to DIN 17100: ST60-2, NFA: a60-2, UNI 7070: FE590 steel grade.Adhere to the spirit of quality first and user foremost, carry out maintenance and other work according to the requirements of the buyer's contract, and ensure that the engineering project and product after-sales play their application effectiveness.
