When it comes to developing industry-wide standards, two of the most influential organizations are the American Iron and Steel Institute (AISI) and the American Society for Testing and Materials (ASTM). While both groups share common goals, there are some key differences between their approaches. In this blog post, we’ll take a look at those differences and explore how they impact metal fabricators. Stay tuned!
What is AISI?
The AISI (American Iron and Steel Institute) is a trade association that represents the steel industry in the United States. AISI’s members include companies that produce steel as well as those that use it in their products. AISI is dedicated to promoting the use of steel and working with its members to improve the competitiveness of the U.S. steel industry. AISI also supports research and development in the steel industry and provides statistical data and analysis of the industry.
What is ASTM?
- ASTM (American Society for Testing and Materials) ASTM International, formerly known as the American Society for Testing and Materials, is an international standards organization that develops and publishes voluntary consensus technical standards for a wide range of materials, products, systems, and services. Some 12,575 ASTM voluntary consensus standards operate globally.
- The organization’s headquarters is in West Conshohocken, Pennsylvania, about 5 mi (8.0 km) northwest of Philadelphia. ASTM, founded in 1898 as the American Section of the International Association for Testing and Materials, grew out of concerns identified by manufacturers during the industrialization of the United States at the end of the 19th century. Local scientists and engineers were concerned with the need for agreement on such things as the mechanical properties of materials used in construction and product liability issues related to the deterioration of materials over time.
- A group met in Philadelphia in 1898 to address these needs. Because representatives from companies located throughout the United States were involved in this effort, it was decided to form a national organization that would serve industry throughout America. It was also recognized that international participation would be beneficial. Today more than 30 percent of ASTM standards are adopted worldwide.
Difference between AISI and ASTM
- AISI and ASTM are both organisations that develop standards for materials, including steel. AISI stands for the American Iron and Steel Institute, while ASTM is the American Society for Testing and Materials. While both AISI and ASTM standards are voluntary, they are often required in order to obtain certain certifications or to access certain markets.
- AISI standards tend to focus on the manufacture of steel products, while ASTM standards cover a wider range of material types, including metals, plastics, and ceramics. In terms of steel standards, AISI and ASTM have developed a number of similar standards, but there are also some significant differences. For example, AISI uses a letter-based designation system for steels, while ASTM uses a numeric designation system.
- In addition, AISI standards are typically developed by committees made up of representatives from steel producers, while ASTM committees include representatives from a wider range of stakeholders, including consumers and government representatives. As a result of these differences, AISI and ASTM standards can sometimes conflict with each other. However, in general, both AISI and ASTM provide valuable guidance for materials testing and certification.
Conclusion
The American Iron and Steel Institute (AISI) and ASTM International are two organizations that develop steel standards. There is a big difference between the two organizations, which can be confusing for buyers. In this blog post, we’ve outlined the main differences between AISI and ASTM so you can make an informed decision when choosing a standard.
