Applications of Nitriding Steels

Nitriding steels, as covered in this standard, are renowned for their excellent wear resistance, fatigue strength, and corrosion resistance. These properties make them ideal for a variety of applications, including:

• Automotive Industry: Used in the manufacturing of gears, crankshafts, and camshafts, where high surface hardness and fatigue resistance are essential.
• Aerospace Sector: Employed in the production of components that require high strength-to-weight ratios and resistance to extreme conditions.
• Tool and Die Making: Ideal for tools and dies that require a hard surface to withstand repeated use and wear.

Understanding the Importance of Heat Treatment

Heat treatment is a critical process in the production of nitriding steels, as it enhances their mechanical properties and performance. The BS EN ISO 683-5:2021 standard provides detailed instructions on the appropriate heat treatment processes, ensuring that the steels achieve the desired hardness and strength.

Benefits of Heat Treatment

• Improved Hardness: Heat treatment increases the surface hardness of nitriding steels, making them more resistant to wear and tear.
• Enhanced Strength: The process improves the overall strength of the steel, allowing it to withstand higher loads and stresses.
• Better Durability: Treated steels have a longer lifespan, reducing the need for frequent replacements and maintenance.

BS EN ISO 683-5:2021

This standard BS EN ISO 683-5:2021 Heat treatable steels, alloy steels and free-cutting steels is classified in these ICS categories:

• 77.140.20 Stainless steels
• 77.140.10 Heat-treatable steels

This document gives the technical delivery requirements for

• semi-finished products, e.g. blooms, billets, slabs (see note 1),

• bars (see note 1),

• wire rod,

• hot-rolled plates (see note 2), and

• hammer or drop forgings (see note 1)

manufactured from the nitriding steels listed in Table 3 and supplied in one of the heat-treatment conditions given for the different types of products in Table 1, rows 2 to 5, and in one of the surface conditions given in Table 2.

The steels are generally intended for the fabrication of quenched and tempered and, subsequently, nitriding machine parts.

The requirements for mechanical properties given in this document are restricted to the sizes given in Table 6.

NOTE 1 Hammer-forged semi-finished products (blooms, billets, slabs, etc.), seamless rolled rings and hammer-forged bars are in the following covered under semi-finished products or bars and not under the term “hammer and drop forgings”.

NOTE 2 The term “plate” includes in the following also wide flats unless otherwise stated.

In special cases, variations in these technical delivery requirements or additions to these requirements can form the subject of an agreement at the time of enquiry and order (see 5.2 and Annex B).

In addition to this document, the general technical delivery requirements of ISO 404 are applicable.
