S355J0H is a low alloy structural steel that is part of the European standard (EN 10025) and is used
The chemical composition of S355J0H mainly includes carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S) and other elements. The specific chemical composition content is usually as follows:
| C | Si | Mn | P | S |
| ≤0.22% | ≤0.55% | ≤1.60% | ≤0.025% | ≤0.025% |
355J0H steel has the following notable features:
1. High strength: S355J0H steel has high yield strength and tensile strength, which enables it to adapt to structural designs with various strength requirements and provide stable and reliable structural support.
2. Good weldability: This kind of steel has good weldability and can be connected by conventional welding methods, which facilitates assembly and connection during the construction process.
3. Good weather resistance: S355J0H steel can be used for a long time under harsh climate conditions without losing its mechanical properties, and has good durability and stability.
4. Excellent corrosion resistance: In the atmospheric environment, S355J0H steel can resist the erosion of oxidation and other chemical substances, and has good corrosion resistance, thereby extending its service life.
S355J0H has a wide range of applications, mainly reflected in the following aspects: Building structure: S355J0H can be used in load-bearing structures and supporting components of buildings, such as steel columns, steel beams and steel pipe trusses. pidge construction: This material is suitable for the construction of various types of pidges, such as highway pidges, railway pidges and urban road pidges, etc. Machinery manufacturing: S355J0H can be used as structural support parts for heavy machinery and equipment, such as cranes, excavators and loaders. Pipework: The material is also commonly used in pipework in industries such as the oil, gas and chemical industries.
