Stocked Grades

Through Hardening Steel

Having spent many years finding solutions and supplying the most optimum steel alloys suited for high strength critical application, we stock a large selection of through hardening steel grades.

If you require a through hardening steel grade that we do not have in stock, our extensive network of steel suppliers and dedicated steel experts are happy to recommend suitable alternatives or source the metals you need.

Giving our clients as much value as possible and delivering you steel in the exact form required for your manufacturing process is our uppermost priority. This is why we offer a comprehensive range of processing services such as heat treatment, cutting and machining.

Our friendly and reliable sales team is here to help and would love to give you more information on how Hillfoot’s technical, logistical, supply chain management and export services can limit costs and save your business time.

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.
