High strength steel plate manufacturers introduce high strength steel plate refers to some relatively high strength steel plate materials, this material is mainly used in large bridge construction and large Marine machinery industry. The high construction steel plate is generally used for high-rise building construction materials, with seismic, low temperature resistance and impact resistance. Now let's distinguish the difference between high strength steel plate and high construction steel plate.
1, high strength steel plate refers to the brand Q420 steel, high strength, especially in the normalizing or normalizing and tempering state has high comprehensive mechanical properties. Mainly used for large ships, Bridges, power plant equipment, medium and high pressure boilers, high pressure vessels, locomotives and vehicles, lifting machinery, mining machinery and other large welded structural parts.
2, high performance building structure steel referred to as high construction steel, it has easy welding, seismic, low temperature impact resistance and other properties, mainly used in high-rise buildings, super high-rise buildings, large span sports venues, airports, exhibition centers and steel structure workshop and other large construction projects. Compared with common carbon or low alloy steel plate, the yield strength of Gaojian steel plate has set the upper limit, the tensile strength has been increased, and the carbon equivalent and yield ratio indexes are required. Under normal circumstances, the high construction plate is produced by the plate mill, but it is also not excluded that the furnace roll mill and hot strip mill are used to produce. Gaojian board is mainly part of the extra thick plate, thick plate, thick plate, plate, etc. Generally speaking, the thickness of structural steel plates for high-rise buildings is 10 ~ 100MM, the width is 1600 ~ 3500MM, and the length is 6000 ~ 18000MM.
High strength plate manufacturers believe that high strength plate and high construction steel are very good steel plate materials, in their respective application fields have played a very good role, we can according to their own needs to carry out procurement and application!
