Are there any industry specifications for SM400 steel plate?

There are industry specifications that apply to SM400 steel plates. The primary specification for SM400 steel plate is governed by the Japanese Industrial Standards (JIS). Specifically, JIS G3106 is the standard that covers hot-rolled steel plates, sheets, and shapes for welded structures, including SM400.

JIS G3106 specifies the chemical composition, mechanical properties, dimensions, tolerances, and other requirements for SM400 steel plates. It provides guidelines for manufacturing and quality control processes to ensure consistency and reliability in the production of these plates.

Apart from JIS specifications, SM400 steel plates may also comply with international standards depending on the application and customer requirements. For example, equivalent grades under other international standards, such as ASTM A36 or EN 10025-2 S235JR, can be considered in certain cases.

When procuring SM400 steel plates, it is important to refer to the applicable industry specifications, consult with suppliers or manufacturers, and ensure compliance with the required standards to meet the specific project or application needs.
