European standard channel steel S235JR and S355JR are rich in variety.
With the continuous development of industry and construction, the demand for steel is also increasing. Among them, European standard channel steel, as an important construction steel, is widely used in various construction projects. S235JR and S355JR, as two important varieties of European standard channel steel, have a wide range of application prospects. This article will give a detailed introduction and comparison of these two varieties of European standard channel steel, so as to better meet the needs of readers.
1. S235JR European standard channel steel.
S235JR European standard channel steel is a high-strength steel with a yield strength of 235MPa and a tensile strength of 370-500MPa. This variety of channel steel has good plasticity and toughness, and can meet the processing requirements of various complex shapes. At the same time, S235JR European standard channel steel also has good welding performance and corrosion resistance, and can adapt to various harsh environmental conditions.
In terms of application, S235JR European standard channel steel is mainly used in the manufacture of structural parts in the fields of construction, bridges, ships, vehicles, heavy machinery, etc. Due to its excellent mechanical properties and processing properties, S235JR European standard channel steel has been widely used in the construction field, such as the manufacture of beams, columns, plates and other structures of high-rise buildings.
2. S355JR European standard channel steel.
S355JR European standard channel steel is a high-strength steel with a yield strength of 355MPa and a tensile strength of 490-620MPa. Compared with S235JR European standard channel steel, S355JR has higher strength and can withstand greater load and pressure. At the same time, the S355JR also has good low-temperature performance and corrosion resistance, and can be used in extreme temperature and corrosive environments.
In terms of application, S355JR European standard channel steel is mainly used in the manufacture of structural parts in the fields of heavy machinery, large bridges, high-rise buildings and other fields. Due to its high strength and excellent processing properties, S355JR has been widely used in the field of heavy machinery, such as large ships, petrochemical equipment, etc. At the same time, it is also widely used in the manufacture of beams, columns, slabs and other structures of high-rise buildings.
