Assab Steels CARMO Cold Work Steel

 

Subcategory: Tool Steel; Chrome-moly Steel; Cold Work Steel; Metal

Material Notes:
CARMO is a high-strength, flame-induction and through hardening steel delivered prehardened to 240-270 HB.
The surface of the steel can be flame-hardened without water cooling to a hardness of 58±2 HRC. The depth of hardness is normally 4-5 mm and the hardened and tempered matrix is a good base for the flame-hardened layer. The steel can be easily repair welded and has a high wear resistance similar to that of A2. The toughness of CARMO is much better than that for the steel types A2 and D2.

CARMO is a cold work tool steel which has been developed together with the automotive industry. Its analysis has been balanced to give one universal tool steel for car body dies instead of the several steel grades (flame hardening and through hardening grades) which are normally used. The steel can be used in the flame-hardened or in the through-hardened condition for blanking and forming of both car body parts (thin sheet) or structural parts (thicker sheet).
