SY390 Steel: The Key Steel Supporting Heavy - load Projects
SY390 is a low - alloy high - strength steel. Through careful deployment of alloy composition, it has high load - bearing capacity and excellent durability. When bearing heavy loads and complex stresses, it can still maintain the integrity of the structure, and it has good fatigue resistance.
In terms of size specifications, the thickness of the plate is usually between 5 - 120mm, and there are also diversified choices of profiles, which can be customized according to the actual needs of the project.
SY390 is mainly used in heavy - load engineering fields such as metallurgy and lifting. In metallurgical equipment, it is used to manufacture key components such as load - bearing beams to support heavy structures such as furnace bodies. In large - scale lifting equipment, as the steel for the boom structure, it ensures the safe lifting of heavy objects. With its excellent performance, it has become the key supporting steel in the field of heavy - load engineering.
