API2HGr50 delivery status: steel is usually delivered in hot rolled or hot forged state. It can also be delivered in the state of heat treatment (annealing, normalizing or high temperature tempering). Annealing: The steel corten a anti-rust steel is heated to a suitable temperature and slowly cooled according to the heating time of different materials and specifications. Normalizing: Heat the steel plate to a suitable temperature and cool it in the air. Tempering: Keep the steel plate at an appropriate temperature for a long time while keeping it cool.
Compared with thick steel plates, corten a anti-rust steel, thin steel plates have many obvious advantages in steel plate processing and use. It is precisely these advantages of thin steel plates that make them more and more popular in various industries. First, compared to those thicker steel plate materials, thin steel plates are generally thinner in thickness. Thin steel plates themselves are lighter and thinner, and their weight is lighter, which is very convenient for handling during construction and transportation. It can save some storage and transportation space.
In order to obtain the seamless tube with smaller size and better quality, the method of cold rolling, cold drawing or the combination of the two must be used. Cold rolling is usually carried out on a two high mill, and corten a anti-rust steel pipes are rolled in a circular pass composed of a variable cross-section circular groove and a fixed conical head. Cold drawing is usually carried out on single chain or double chain cold drawing machines of 0.5-100t.
S355J2 steel plate belongs to European standard low alloy steel, the executive standard is EN10025-2. Delivery status: normalizing, hot rolling or control rolling. S355J2 corresponds to the Chinese Q345D, but the executive standard is different, the chemical composition is slightly different, but their mechanical properties are the same. S355J2 low alloy steel plate tensile strength (MPA): 450-680, impact value: - 20 ℃: ≥ 27J. corten a anti-rust steel, S355J2 low alloy steel plate is widely used in bridges, vehicles, ships, buildings, steel structures, etc.
