AISImerkintöjä

AISImerkintöjä refers to the marking system used for stainless steel grades according to the American Iron and Steel Institute (AISI) standards. These markings are typically alphanumeric codes that identify specific types of stainless steel based on their chemical composition and properties. The AISI system, while historically significant, has largely been superseded by the Unified Numbering System (UNS) for metals and alloys, which provides a more comprehensive and standardized approach. However, AISI designations are still frequently encountered in industry, particularly for older specifications or when referring to well-established grades.

Common AISI designations include series like 300, 400, and 200, each representing a different category of stainless steel. For example, the 300 series, such as AISI 304 or AISI 316, are austenitic stainless steels known for their excellent corrosion resistance and formability, often used in food processing equipment and architectural applications. The 400 series, like AISI 410 or AISI 420, are martensitic stainless steels that can be hardened, making them suitable for cutlery and tools. Understanding these AISImerkintöjä is crucial for selecting the appropriate stainless steel for a given application, ensuring desired performance and longevity.
