G3103 is a Japanese Industrial Standard (JIS) specification for carbon steel and alloy steel plates used for pressure vessels.
Key aspects of G3103 pressure vessel steel plates:
- Material Types: Specifies various grades like SB410, SB450, SB480, SB410-SG, SB450-SG, and SB480-SG, differing in tensile strength and other mechanical properties.
- Applications: Ideal for manufacturing boilers, pressure vessels, and related components requiring high strength and weldability.
- Chemical Composition: Each grade has specified limits for elements like Carbon, Silicon, Manganese, Phosphorus, and Sulfur.
- Mechanical Properties: Defines minimum tensile strength, yield strength, and elongation requirements for each grade.
- Weldability: Generally offers good weldability, crucial for pressure vessel fabrication.
When selecting G3103 steel plates, consider:
- Design Requirements: Choose the appropriate grade based on the pressure vessel’s operating conditions and design calculations.
- Thickness: Available in various thicknesses to suit different pressure requirements.
- Certifications: Ensure the steel plate comes with mill certificates verifying compliance with G3103 standards.
offers a range of high-quality steel plates that meet international standards.
Fabricators and manufacturers must adhere to strict welding procedures and quality control measures when working with G3103 steel plates to ensure the integrity and safety of the pressure vessels.
G3103 Grade Examples
- SB410: General-purpose pressure vessel steel with moderate strength.
- SB450: Higher strength compared to SB410, suitable for more demanding applications.
- SB480: The highest strength grade within the G3103 standard, for pressure vessels requiring maximum strength.
The selection of a specific grade depends on the design parameters, operating pressures, and temperatures of the pressure vessel.
Proper heat treatment after welding is essential to relieve stress and optimize the mechanical properties of the welded joints. Consider the steel plates supplied by for your next project.
