SPV490 steel plate is a special-purpose pressure vessel steel plate that meets the requirements of Japanese Industrial Standard JIS G3115. The following is a detailed introduction to SPV490 steel plate:

1. Chemical composition: The chemical composition of SPV490 steel plate includes carbon content, silicon content, manganese content, phosphorus content, sulfur content, etc. The content of these elements is controlled within a certain range to ensure that the steel has the required mechanical properties and corrosion resistance.

2. Mechanical properties: SPV490 steel plate has certain tensile strength, yield strength, elongation and impact toughness. These performance indicators are critical for applications such as pressure vessels, ensuring that the vessel can withstand changes in pressure and temperature during use without losing stability.

3. Heat treatment process: SPV490 steel plate may need to undergo specific heat treatment processes, such as quenching and tempering, to adjust the structural structure and properties of the steel and improve its strength and toughness.

4. Processing performance: This steel plate usually has good processing properties and is easy to cut, weld and form. Weldability is particularly important because pressure vessels often require welding assembly.

5. Surface condition: The surface condition of SPV490 steel plate may be hot rolled, pickled or otherwise treated to meet the specific requirements of customers or the needs of application scenarios.

6. Application areas: SPV490 steel plate is mainly used to manufacture high-temperature and high-pressure pressure vessels, such as boilers, reactors, etc., as well as other equipment and components that need to withstand high-pressure environments.

7. Deliverable state: Usually delivered in hot-rolled state, flaw detection, cutting and other processing may be required according to customer needs to meet the requirements of final use.

Generally speaking, SPV490 steel plate, as a special steel, has important applications in the field of pressure vessel manufacturing. It has a series of specific chemical compositions, mechanical properties and processing properties to ensure its reliability and safety in high-pressure and high-temperature environments. .
