Stocked Grades

Case Hardening Steel

We are committed to stocking a large selection of case hardening steel grades that are suitable for use in the manufacture of a wide range of specialist products.

We have spent many years delivering solutions for customers in the motorsport, off-highway, energy and engineering sectors to identify the materials they need. 

If you require a case hardening steel grade that we do not have in stock our global supply chain and dedicated team of steel experts will be happy to recommend appropriate alternatives or source the metals you require.

We ensure that you will receive your case hardening steel in the exact form needed by taking advantage of our complete processing service. From heat treatment and cutting to forging and machining, our team is dedicated to delivering as much value as possible to you.

Steel Grade Equivalents

The table below details similar steel grades to the most commonly used engineering steels.

The column on the left shows some of the steel grades stocked by Hillfoot, while the middle columns show their steel equivalents, steel grades with similar chemistry, and the two columns on the right display grades for potential substitution.

All grades in blue are stocked by Hillfoot and clicking on the link will take you to a detail page, where you will be able to download a datasheet.

Should you need any technical advice about grade selection or have queries about the price and availability of the steel required for your manufacturing process, our friendly team is easy to reach and will be more than happy to help.

Similar Grades

Grades of similar (not identical) chemistry. Please note the similar grades are based on chemistry only, and may not meet the necessary mechanical properties (in the standard ‘as stocked’ state).

Grades for Potential Substitution

Grades capable of achieving similar mechanical properties (material may need further treatment to achieve the desired properties). The potential substitution grades are based on mechanical properties, not necessarily the chemical analysis.
