: Specifies permissible variations based on the plate's width and nominal thickness. For example, a plate under 1.25 mm thick with a width under 1600 mm typically has a tolerance of
Because JIS G3193 only covers dimensions and tolerances, it is always paired with material quality standards. Common pairings include:
Separate tables for sheets with mill edges and sheared edges. jis g3193 pdf
In conclusion, JIS G3193 is an important standard that specifies the requirements for hot-rolled steel plates used in shipbuilding. The standard's key requirements, including chemical composition, mechanical properties, testing and inspection, and surface quality, help to ensure the quality and safety of shipbuilding materials. As the shipbuilding industry continues to evolve, the JIS G3193 standard will remain a critical component in ensuring the safety and performance of ships.
: Formulae for calculating the theoretical weight of the steel based on its dimensions and the standard density of steel ( Why This Standard Matters : Specifies permissible variations based on the plate's
Understanding the technical nuances outlined within the is crucial for engineers, procurement managers, and quality control inspectors working with structural steels. Scope and Exclusions of the Standard
Practical significance: Engineers and fabricators use JIS G3193 for section selection, structural calculations, and detailing. Contractors rely on its tolerances to plan connections, fits, and welding/bolting operations. Manufacturers follow it to produce consistent profiles and label products. In conclusion, JIS G3193 is an important standard
