The content of the main chemical components of S235J0 usually follows the following range:
| C | Si | Mn | P | S | Cu |
| ≤0.20% | ≤0.55% | ≤1.60% | ≤0.040% | ≤0.40% | ≤0.40% |
The production method of S235J0 mainly includes the following steps:
Steel billet preparation, heating, rough rolling, finish rolling, cooling, straightening, quality inspection.
S235J0 steel plate has a series of remarkable features. The following are its main features:
1. Good weldability, plasticity and processability: S235J0 steel plate can be welded by conventional welding methods, such as arc welding, gas shielded welding, etc. In terms of processing, it can be processed by cutting, cold bending, forming, etc. to adapt to different engineering needs.
2. Higher strength and toughness: S235J0 steel plate has higher tensile strength and yield strength, with a tensile strength range of 360-510MPa and a yield strength of 235MPa. This makes it widely used in structural engineering, and can be used for components such as beams, columns, pidges, towers, etc. in buildings, as well as in the manufacture of mechanical equipment, such as light trucks, cranes, etc.
3. Excellent corrosion resistance: S235J0 steel plate can resist erosion by the atmosphere, water and some chemicals to a certain extent, thus extending its service life. In order to further improve its corrosion resistance, surface treatment can be used, such as hot-dip galvanizing, spraying, etc.
4. Clear impact temperature: "J0" in S235J0 indicates that the impact temperature of the steel plate is 0 degrees impact. This means that the S235J0 steel plate can still maintain good impact toughness in low temperature environments below 0 degrees.
5. Standard implementation: S235J0 steel plate belongs to the American Standard Carbon Structural Steel and implements the European standard EN10025. This makes it widely recognized and applied in the international market.
S235J0 steel plate has a wide range of applications, mainly due to its good weldability, plasticity, processability and high mechanical strength. The following are some main application areas: S235J0 steel plates are very commonly used in the construction field, such as beams, columns, load-bearing walls, floor slabs and other structural parts of buildings. The high strength and corrosion resistance of S235J0 steel plates make it an important material for pidge construction, and is used for the main structure, pidge deck, guardrails and other parts of the pidge. S235J0 steel plates are commonly used to manufacture various machinery and equipment and parts, such as light trucks, cranes, excavators, etc. S235J0 steel plate is widely used in ship hulls, decks, bulkheads and other parts due to its good corrosion resistance and mechanical properties. S235J0 steel plates are commonly used to manufacture various storage tanks, pipes, equipment, etc. Its corrosion resistance and high strength ensure long-term stable operation of equipment in harsh chemical environments.
