JIS G3101 SS 400 Steel Sheet Coil

JIS G3101 SS400 is a Japanese standard for general structural steel. It is one of the most commonly used hot-rolled structural steel grades. SS400 steel is known for its excellent welding and forming properties and is often used in various structural applications. Here are some key features of JIS G3101 SS400 steel sheet coil:

Chemical Composition

SS400 steel has a specified chemical composition that includes elements such as carbon, manganese, phosphorus, sulfur, and others. The exact composition is defined in the JIS G3101 standard to ensure consistency and performance.

Mechanical Properties

SS400 steel should meet specific mechanical properties, including yield strength, tensile strength, elongation, and other characteristics. These properties make it suitable for various structural applications.

Hot-Rolled Process

SS400 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 SS400 steel sheets and coils are widely used in various structural applications, such as buildings, bridges, ships, and other general construction projects. It is also commonly used in the manufacturing of machinery and equipment.

Surface Finish

SS400 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

SS400 conforms to the Japanese Industrial Standard (JIS) G3101. It’s essential to ensure compliance with the specified JIS standard when procuring SS400 steel to guarantee the material’s quality and suitability for the intended application.

Equivalent Grades

SS400 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 SS400 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.
