S355 Stainless Steel Pipe and Tube

S355N is a steel grade that belongs to the hot-rolled non-alloy structural steel in the European standard EN 10025-2. The "S" stands for "structural steel", and the number "355" indicates that its minimum yield strength is 355 MPa. This type of steel is commonly used in structural components and components in buildings, bridges, ships and machine manufacturing. S355N steel has good weldability, plasticity and toughness, as well as high tensile strength and durability. At the same time, its low carbon content gives it good cold forming properties. In order to ensure that the mechanical properties and chemical composition of the material meet the requirements, when using S355N steel, attention should be paid to material selection, processing and use in accordance with relevant standards.S355 steel pipe is available in various sizes and shapes, including round, square, and rectangular shapes. It can also be produced in different finishes, such as black or galvanized, to suit specific requirements. As a versatile material, it can be used for a wide range of applications, such as building structures, bridges, and pipelines.

The production technology and process of S355N steel plate usually includes the following steps:

1. Raw material preparation: Select steel billets that meet the requirements of relevant standards as raw materials, including chemical composition, mechanical properties and other indicators.

2. Smelting: Put the selected raw materials into a high-temperature furnace for smelting. By heating and controlling the temperature in the furnace, the raw materials are completely dissolved and mixed evenly.

3. Continuous casting: Pour the molten steel into the continuous casting machine, cool it through the crystallizer and form a continuous billet. During the continuous casting process, refining and deoxidation of molten steel can be carried out.

4. Hot rolling: The continuous casting billet is heated to a suitable temperature and rolled through the hot rolling unit to gradually reduce the thickness and adjust the width and length of the steel plate. After multiple passes of rolling and cooling, S355N steel plates that meet the requirements are gradually obtained.

5. Steel plate cutting: According to customer needs, the produced steel plates are cut to the required size.

6. Surface treatment: Clean and remove rust on the surface of the steel plate to ensure a smooth and clean surface.

7. Quality inspection: Inspect the chemical composition, mechanical properties, size and appearance of the finished S355N steel plate to ensure that the product meets the standard requirements.

8. Packaging and shipment: After packaging, packaging and other procedures, the qualified S355N steel plates will be properly packaged and shipped from the factory for transportation and use.

It should be noted that the specific production techniques and processes may vary depending on different manufacturers and process equipment. The above is only a brief introduction to the general process. In actual production, corresponding control and adjustments need to be carried out according to relevant standards and technical requirements.
