SB410 Hot Rolled Steel for Pressure Vessels

SB410 Pressure Vessel Steel Description

SB410 Boiler and Pressure Vessel Steel is a high-quality carbon steel designed for applications requiring strength and durability under high-pressure and elevated temperature conditions. Conforming to the JIS G3115 standard, SB410 Hot Rolled Steel is characterized by its exceptional weldability, moderate tensile strength, and resistance to corrosion and oxidation. These properties ensure reliable performance in demanding environments, such as high-pressure and high-temperature conditions, while maintaining cost-effectiveness compared to other steel grades.

JIS G3115 SB410 Pressure Vessel Steel is extensively used in industries such as petrochemical, power generation, and manufacturing. Its primary applications include:

• Boilers and pressure vessels
• Heat exchangers
• Petroleum and chemical processing equipment
• Power plant components The steel’s ability to withstand heat and pressure, combined with its weldability, makes it ideal for constructing reactors, separators, and spherical tanks in these sectors.
