JIS SPV490 JIS G3115
Boiler and Pressure Vessel Steel Product Introduction
JIS SPV490 JIS G3115 is an industrial standard set by the Japanese Industrial Standard Committee (JISC) that specifies the basic requirements for low- and intermediate-tension carbon steel plates for pressure vessels with a thickness greater than or equal to 3.2mm. Developed to handle pressure containment vessels of various sizes, the standard emphasizes on quality and performance in essential areas such as strength, elongation, weldability, and corrosion resistance. It is applicable to all types of welded structures that are exposed to heat, pressure, and the environment. The various types of plates offered by this standard include those that have a low-tensile strength of up to 270MPa, those with a medium-tensile strength of up to 510MPa, and those with a high-tensile strength of up to 760MPa.

JIS SPV490 JIS G3115 Mechanical properties
JIS SPV490 JIS G3115 steel is ideal for the production of pressure vessels due to its many advantages. These include its exceptional strength, excellent scalability, reliable weldability, and good corrosion resistance. It is capable of withstanding high pressures and temperatures and is less prone to cracking due to its high levels of elongation. This steel is also highly resistant to oxidation and other forms of corrosion, which makes it ideal for use in industries that require frequent exposure to harsh weather conditions and extreme temperatures. Additionally, it has a low cost compared to other types of steels, making it a more attractive choice for cost-sensitive projects.

JIS SPV490 JIS G3115 Physical properties
The physical properties of JIS SPV490 JIS G3115 include high strength, low weight, durability, ductility and resistance to corrosion. Steel, as we all know, offers great strength though it is light in weight. In fact, the ratio of strength to weight for steel is the lowest than any other building material available to us.
