What is EN ISO 683-2:2021

EN ISO 683-2:2021 is an international standard that provides guidelines and specifications for the heat treatment of steel products. This standard, published by the International Organization for Standardization (ISO), is part of the broader EN ISO 683 series, which covers various aspects of steels for quenching and tempering.

Understanding the Purpose

The primary purpose of EN ISO 683-2:2021 is to set out the requirements for heat treatment processes such as hardening, tempering, and annealing. By following these guidelines, manufacturers can ensure that the resulting steel products possess the desired mechanical properties. These properties include hardness, toughness, and resistance to wear and fatigue.

Key Features and Specifications

EN ISO 683-2:2021 specifies the methods for heat treatment, including the heating and cooling rates, holding temperatures, and required property values. It also provides information on the types of furnaces, quenching media, and testing procedures recommended for achieving the desired results. Additionally, it outlines the various steel grades for which these heat treatment guidelines apply.

Benefits and Applications

Adhering to EN ISO 683-2:2021 ensures consistency in the heat treatment process, leading to improved product quality and performance. Steel producers and manufacturers rely on this standard to meet customer requirements for a wide range of applications. These include automotive parts, machine components, tools, construction materials, and many other industries where high strength and durability are essential.
