JIS SPV 50 JIS G3115 Steel Plate
boiler steel sheet Product Introduction
JIS SPV 50 JIS G3115 is a Japanese industrial standard for low- and intermediate-tension carbon steel plates for pressure vessels used in the manufacturing and construction industry. It is often used in the production of boilers, containers, heat exchangers, and other pressure-containing vessels. This industrial standard is designed to emphasize quality and performance in essential areas such as strength, elongation, weldability, and corrosion resistance.

JIS SPV 50 JIS G3115 Mechanical Properties
There are three main categories of JIS SPV 50 JIS G3115 steel; steel plates with low-tensile strength, those with medium-tensile strength and those with high-tensile strength. Low-tensile steel plates have a tensile strength of up to 270MPa and are most commonly used in the production of boilers, container-parts, shells, and light regional ships. Medium-tensile steel plates have a tensile strength of up to 510MPa and are primarily used for intermediate-pressure vessels due to their high levels of toughness. High-tensile steel plates have a tensile strength of up to 760MPa and are mostly used in the production of high-pressure vessels for the oil and gas industry and in petrochemical plants.
