JIS G3101 SS 330 Steel Sheet Coil

JIS G3101 SS330 is a Japanese standard for general structural steel. It is one of several grades under the JIS G3101 standard, which specifies the technical delivery conditions for hot-rolled steel plates, sheets, and strips for general structural usage. SS330 is commonly used for various structural applications due to its good weldability, formability, and strength characteristics.

Here are some key features of JIS G3101 SS330 steel sheet coil:

Chemical Composition

SS330 steel has a specified chemical composition, including elements such as carbon, manganese, phosphorus, and sulfur. The exact composition is defined in the JIS G3101 standard to ensure consistency and performance.

Mechanical Properties

SS330 steel should meet specific mechanical properties, including yield strength, tensile strength, elongation, and other characteristics. These properties are essential for determining the material’s suitability for general structural applications.

Hot-Rolled Process

SS330 steel is typically produced through a hot-rolling process, where the steel slab is heated and then passed through rollers to achieve the desired thickness. This process imparts certain mechanical and structural properties to the steel.


JIS G3101 SS330 steel sheets and coils are commonly used in various structural applications, such as bridges, buildings, and other general construction projects.

Surface Finish

SS330 steel sheets and coils may have different surface finishes based on customer requirements. Common finishes include pickled and oiled, as well as mill scale.

Standards and Certification

SS330 conforms to the Japanese Industrial Standard (JIS) G3101. It’s essential to ensure compliance with the specified JIS standard when procuring SS330 steel to guarantee the material’s quality and suitability for the intended application.

Equivalent Grades

SS330 may have equivalent grades in other international standards, such as ASTM or DIN. Identifying equivalent grades helps ensure that the material meets similar specifications across different standards.

When working with JIS G3101 SS330 steel sheets and coils, it is important to follow recommended processing and handling guidelines to maintain the material’s integrity and performance. Users should also consult the relevant standards and specifications to ensure proper application and compatibility with their specific requirements.
