To determine whether shipbuilding steel plates meet the specification requirements of RINA (Registro Italiano Navale) certification, the following aspects can be considered:

I. Check certification documents
Request the certification certificate issued by RINA from the supplier to confirm that the steel plate's manufacturer and product model are within the certification scope.
Check the validity period of the certification certificate to ensure it is still effective when in use.
Review the product quality certificate, which should contain detailed information such as the chemical composition, mechanical properties, and dimensional specifications of the steel plate. This information should comply with the RINA certification requirements.

AH36

We supply grade AH36 high strength structural shipbuilding steel to the ASTM A131: Part 4 specification.

We supplies Grade AH36 to the world's master shipbuilders in accordance with the classification society of your choice. The material can be supplied as heavy plates, surface treated plates and fabricated sections.

The steel is used in the construction of container ships, bulk carriers and commercial ships such as liners and ferries.

 

 

 

II. Check chemical composition
Use professional chemical analysis equipment or entrust a third-party testing agency to test the chemical composition of shipbuilding steel plates.
Compare the test results with the chemical composition ranges specified in the RINA certification requirements, including the contents of major elements such as carbon, silicon, manganese, sulfur, and phosphorus.
Pay special attention to the control of harmful elements such as sulfur and phosphorus. Their contents should be within the specified lower limits to ensure the welding performance and toughness of the steel plate.
