Acier américain Crucible - CPM S90V

Crucible steel - CPM S90V, a unique tool steel from powder metallurgy.

The CPM S90V is a grade developed by the American company Crucible Industries, known for the quality of its special steel grades. The CPM S90V is developed by powder metallurgy (hence its name, CPM meaning Crucible Particle Metallurgy), which guarantees it incomparable finesse and purity.

The CPM S90V, ideal for bushcraft and outdoor knives.

The Crucible grade CPM S90V is ideal for making bushcraft and outdoor knife blades. Indeed, its high Vanadium rate gives it a truly exceptional wear resistance, in addition to excellent corrosion resistance and strong edge hold. Thus, the S90V MPC Crucible Industries can easily replace D2 steel (Z160CDV12) for applications where corrosion resistance is paramount.

Thermal treatment of CPM S90V: what temperatures?

You can find all our tips about the thermal treatment of this exceptional grade in its technical sheet, freely available online. The CPM S90V is soaked at high temperatures (between 1150 and 1175°C) and requires rapid cooling, air or oil. The income of the S90V CPM is a crucial step that requires controlling its temperatures: making an income between 425 and 540°C may weaken the S90V CPM, and decrease its resistance to corrosion.
