The production process of I-shaped steel mainly includes steps such as continuous casting billet preparation, heating, rolling, cooling, straightening, and cutting the head and tail. Among them, rolling is a key process, and by controlling parameters such as rolling temperature, speed, and deformation, the required shape and properties of I-beams can be obtained.
The advantages of S275JR I-beam include high load-bearing capacity, lightweight, excellent weldability, and high stability, making it an important material in industrial production and construction industries. S275JR I-beams are mainly divided into three types: hot-rolled, cold-formed, and straight seam welded. The application scope of different types also varies. The delivery status is the default hot rolling status.
S355JR I-beam is suitable for various engineering structures that need to withstand large loads, such as bridges, building frames, mechanical manufacturing, and ship manufacturing. Its excellent strength and plasticity make S355JR I-beam the preferred material to withstand high-strength loads, providing reliable guarantees for the safety and stability of engineering structures.
SS400 I-beam is a type of steel produced by hot rolling process, belonging to low alloy high-strength structural steel. Its name comes from the Japanese standard JIS G3101, where "SS" represents structural steel and "400" represents the lower limit of yield strength of 400 MPa. SS400 I-beam has high strength, good plasticity and toughness, and is widely used in fields such as construction, bridges, ships, vehicles, and containers.
ST37 I-beam has good plasticity and toughness, is not easily brittle, and can maintain structural stability and reliability while bearing large loads. This type of steel has a high elongation and cross-sectional shrinkage, which can effectively absorb energy impacts and improve the fatigue resistance of the structure.
Q235 I-beam is a type of carbon structural steel with high yield strength. According to different impact temperatures, Q235 I-beam is divided into four types: Q235A, Q235B, Q235C, and Q235D, which are mainly related to the impact performance of the product at different temperatures. Q235 I-beam has a wide range of applications and can be applied in various fields such as construction, bridges, ships, and vehicles.
