Q355NH material has a protective rust layer that resists atmospheric corrosion and can be used to manufacture low-alloy structural steels for steel structures such as vehicles, bridges, towers, containers, etc. It can also be used to manufacture structural parts such as containers, railway vehicles, oil derricks, seaport buildings, oil production platforms, and containers containing hydrogen sulfide corrosive media in chemical and petroleum equipment.

Because a573 gr 65 structural steel mild plate, boiler steel plate is a product of important use, the safety and reliability requirements are strict, and the manufacturing technology is difficult. The boiler steel plate material must have the following main characteristics:The boiler steel plate has high yield strength performance in a certain temperature range (medium temperature and high temperature);The boiler steel plate has sufficient toughness, no brittle failure accident will occur during manufacturing or use.

AR400 wear resistant steel is a special structural steel with high wear resistance. Generally speaking, the higher the hardness, the higher the wear resistance of the steel, a573 gr 65 structural steel mild plate. The average hardness of AR400 wear-resistant special structural steel is 400HB. After quenching, AR400 wear resistant steel has good martensite bainite microstructure. The addition of Molybdenum (Mo), Nickel (Ni) and Boron (B) alloys ensures uniform texture in the whole thickness direction of AR400 wear resistant steel.
