As an important metal material, stainless steel has been widely used in various industries. As two main quality standards, European standards and American standards regulate and evaluate the quality and performance of stainless steel. Let us compare European and American stainless steel standards to provide you with a more comprehensive selection guide.
First of all, the European stainless steel standard (EN standard) focuses on the chemical composition and mechanical properties of the overall material. The European Standardization Committee has developed a series of standards covering all aspects of stainless steel, such as EN 10088-1 (general technical delivery conditions for stainless steel), EN 10088-2 (chemical composition of stainless steel), EN 10088-3 ( Mechanical properties of stainless steel), etc. The European standard emphasizes the material composition and performance parameters of stainless steel to ensure that it meets the requirements of the European market and is suitable for various application fields.
Compared with this, the American stainless steel standard (ASTM standard) pays more attention to the physical properties and process characteristics of the material. The American Society for Testing and Materials has developed a series of standards covering the quality and performance of stainless steel, such as ASTM A240 (General Specification for Stainless Steel Plate, Strip, and Rings), ASTM A276 (Stainless Steel and Hot-Workable Alloys) Standard specification for steel bars), etc. American Standard focuses on the physical properties and process performance of stainless steel to ensure its adaptability and reliability during production and processing.
In addition, there are some differences in test methods and specification details between stainless steel European standards and American standards. European standards usually use metric units for testing and focus on parameters such as impact strength and elongation of the material to ensure the stable performance of stainless steel under various stress conditions. American standards prefer to use imperial units and focus on the hardness, tensile strength and other parameters of the material to ensure the reliability of stainless steel in different temperatures and environments.
When choosing stainless steel materials, you should decide whether to use European standards or American standards based on specific needs and application environments. If your market is mainly for Europe, then following European standards is a more appropriate choice; and if your market is mainly for the United States, then following American standards is more advantageous. Of course, in some cases you may need to combine both standards to ensure the quality and performance of stainless steel materials.
To sum up, there are some differences in the formulation and evaluation of quality standards between stainless steel European standards and American standards. The European standard focuses on the chemical composition and mechanical properties of the material and is suitable for the European market; the American standard focuses on the physical properties and process characteristics of the material and is suitable for the American market. When selecting stainless steel materials, appropriate standards should be determined based on specific needs and market positioning, and selected in conjunction with relevant test methods and specification details to ensure that the quality and performance of stainless steel meet expected requirements.
