Astm A36 Mild Ship Building Hot Rolled Carbon Steel Plate

The national standard GB/T 712-2011 "Structural Steels for Ships and Offshore Structures" for the thickness standard of shipbuilding steel plates is formulated in the following ways:

 

Demand Research and Analysis:

 

Demand in the shipbuilding industry: Conduct research on the demand for steel plate performance and thickness in the shipbuilding industry. Different types of ships (such as cargo ships, passenger ships, oil tankers, etc.), different parts (such as ship hull shells, decks, bulkheads, etc.), and different navigation environments (ocean-going, coastal, inland rivers, etc.) have different requirements for steel plate thickness. For example, the hull shell of a large ocean-going cargo ship needs thicker steel plates to withstand huge seawater pressure and cargo weight; while for some parts of small inland river ships, relatively thinner steel plates may meet the requirements.

Safety and performance requirements: Consider various loads and environmental conditions that ships face during navigation to ensure that the steel plate thickness can meet the safety performance requirements of ships such as structural strength, stability, impact resistance, and fatigue resistance. For instance, when encountering severe sea conditions, the ship's hull structure needs sufficient strength to resist wave impacts and wind forces, which imposes corresponding requirements on the thickness and performance of steel plates.

 

Related Technical Research and Accumulation:

 

Material science research: Conduct mechanical property tests and metallographic analyses on steels of different compositions and thicknesses to understand the variation laws of properties such as strength, toughness, and weldability with thickness. For example, through research, it is found that increasing the thickness of steel plates may increase their strength but may reduce their toughness. It is necessary to find a suitable balance to meet the requirements of ship use.

Manufacturing process research: Study the production and manufacturing processes of steel plates, including the influence of processes such as smelting, rolling, and heat treatment on the performance and thickness of steel plates. Optimize the production process to ensure that the produced shipbuilding steel plates can have stable quality and performance at different thicknesses.

 

Reference to International Standards and Experience:

 

Borrowing from international standards: Refer to advanced international shipbuilding steel plate standards, such as relevant standards formulated by the International Organization for Standardization (ISO), the American Bureau of Shipping (ABS), and the Det Norske Veritas (DNV). Analyze their regulations and requirements for steel plate thickness and reasonably borrow and absorb them in combination with China's actual situation.

Reference to foreign experience: Understand the experience and practices of foreign shipbuilding industries in the selection and application of shipbuilding steel plate thickness, especially in countries that are leading in the field of shipbuilding. Through comparative analysis, summarize shipbuilding steel plate thickness standards suitable for China's national conditions.

 

Expert Demonstration and Opinion Solicitation:

 

Expert team demonstration: Organize experts in fields such as ship design, manufacturing, and material research to demonstrate the preliminarily formulated shipbuilding steel plate thickness standard. Based on their professional knowledge and practical experience, experts put forward opinions and suggestions from aspects such as technical feasibility, economic rationality, and industry adaptability.

Industry opinion solicitation: Widely solicit opinions from relevant units such as shipbuilding enterprises, steel production enterprises, scientific research institutions, and classification societies. These units have accumulated rich experience in actual production and application, and their opinions are of great significance for the improvement and operability of the standard.

 

Test Verification and Revision and Improvement:

 

Test verification: Conduct a large number of physical tests according to the steel plate thickness and related performance requirements specified in the standard, including mechanical property tests, welding tests, corrosion resistance tests, etc. Verify the rationality and feasibility of the standard through test results. For example, conduct tensile tests and impact tests on steel plates of different thicknesses to detect whether their strength and toughness indicators meet the standard requirements.

Revision and improvement: Revise and improve the standard according to the problems found in the test verification process and the opinions and suggestions solicited. Continuously optimize the regulations on steel plate thickness and related technical indicators to ensure that the standard can meet the development needs of China's shipbuilding industry and keep pace with international advanced levels.
