Alloying designation systems standard lists and material classification

Introduction to the Euronorm Standard Designation System

This article examines the European Norm (EN) standard designation system, established to create a unified language for steel specification across Europe. Since 1988, these mandatory standards have gradually replaced national systems in 18 Western European countries. The article details the structure and implementation of EN standards, their relationship with international standards through ISO, and their comprehensive coverage of steel products.

Introduction to the GB Standard Designation System

The GB standard designation system is a comprehensive framework for classifying iron, carbon, and alloy steels in China. It outlines various delivery conditions and provides specific designations for different types of steel, including structural, tool, and stainless steels. This article explains the structure of GB designations, their meanings, and the relevant standards.

Introduction to the GOST Designation System

Introduction to the JIS Designation System

The Japanese Industrial Standards (JIS) system provides a comprehensive framework for categorizing industrial specifications across various sectors. Created by the Japanese Industrial Standards Committee (JISC), this system begins with the prefix "JIS," followed by a letter denoting the industry division, and then four digits for specific identification.

Introduction to the SAE AMS Designation System

Introduction to the SAE-AISI Designation System

This article explains the standardized SAE-AISI designation system for carbon and alloy steels. The system primarily uses a four-digit numerical code to identify different steel grades based on their chemical composition.
