Acier Crucible - CPM MagnaCut

MagnaCut CPM steel, specially designed and developed for cutlery.

MagnaCut CPM is a semi-inoxidable steel manufactured by Crucible Industries, an American company renowned for its expertise in special steels. This very special shade was developed specifically for cutlery, and to meet the needs of the most demanding cutlery.

A technical grade specially designed for cutlery.

The MagnaCut CPM is a semi-inoxidable steel made by powder metallurgy, which guarantees it a finesse and purity incomparable with those of more "conventional" steels. His composition was developed by Larrin Thomas, a doctor in metallurgy, whom English cutlery know well: it is indeed his very extensive studies that feed the blog Knife Steel Nerds, a reference for amateurs. Larrin Thomas wanted to develop a steel that could meet all the requirements of the cutlery. The MagnaCut MPC will meet the most demanding expectations, as it combines the qualities:

• Its tenacity / sharpness ratio is exceptional
• It is extremely resistant to corrosion
• High purity, very fine structure
• High hardness allowed according to heat treatment led.

MagnaCut CPM, for all types of high-end knives.

Due to its many technical qualities, the MagnaCut CPM is suitable for all types of knife blades, hunting, outdoor or folding. It will prove particularly interesting for the making of blades or the edge must be fine and stable, like the Japanese kitchen knives.

MagnaCut CPM, extremely resistant to corrosion.

The composition of CPM MagnaCut steel makes it extremely resistant to corrosion. For example, Spyderco, a famous American knife manufacturer, has chosen this unique shade to make the Native 5 Salt, a knife that is part of the Salt Series: the knives of this Spyderco series are designed for marine use, in salt water.

How do I reveal the potential of MagnaCut CPM to quench?

You can find all our tips for the thermal treatment of this unique shade in its technical sheet, freely searchable and downloadable. MagnaCut CPM steel soaks at 1120°C for a minimum of 20 minutes. Fast cooling, either under plates or oil, is required. A well-conducted yield allows for significant hardness, which can increase further by increasing the austenitization temperature and/or lowering the income temperature.

Attention: Due to its chromium content, MagnaCut CPM steel cannot be considered as stainless steel. It will therefore not be suitable for food use.
