STEELS

Allen Foundry offers a select range of steels. These include low to medium carbon steels and a Nickel-Chromium-Molybdenum Steel.

The low to medium carbon steels are good for a range of general engineering applications.

The Nickel-Chromium-Molybdenum Steel is a good intermediary material between white cast iron and plain carbon steels. It offers good toughness coupled with a high abrasion resistance, which is due to the high initial hardness.
