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 The AISI system, while historically significant, has largely been superseded by the Unified Numbering System (UNS) for metals and alloys, which provides a more comprehensive and standardized approach.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
