International steel standards
International steel standards are a set of technical specifications developed by international organizations to standardize the quality, properties, and characteristics of steels used in various industrial sectors. These standards help ensure the quality and consistency of the steel used around the world and are essential to ensure the safety and reliability of structures and products made from steel.
Types of standards
There are several types of international steel standards used in the industry, each focusing on different aspects of steel materials. Some of the more common types of standards include:
Quality standards: These standards specify quality requirements for steel, such as chemical composition, mechanical properties, and microstructure. Some of the most used quality standards are the ASTM standard, the EN standard, and the JIS standard.
Design Standards: These standards establish design requirements for steel structures, including loading criteria, service conditions, and safety factors. Some of the most common design standards are the AISI standard, the Eurocode standard, the CSA standard, AWS and the ISO standard.
Fabrication Standards: These standards specify manufacturing requirements for steel, including production methods, welding requirements, and inspection procedures. Some of the most used manufacturing standards are the AWS standard, the EN standard and the ISO standard.
Classification of international standards
International steel standards are also classified according to the geographic region or country where they are used. Some of the major international organizations that set steel standards include the International Organization for Standardization (ISO), the American Association of Steel Engineers (AISC), and the European Committee for Standardization (CEN).
In summary, International Steel Standards are an essential component of the steel industry and are used to ensure the quality and reliability of steel used around the world. There are several types of standards that focus on different aspects of steel, and these standards are categorized based on the geographic region or country where they are used.
