Case Study: Aluminum Foil Slitter
A Vietnamese converter slitting 30 µm aluminium foil at 400 m/min was getting 5 days from a D2 slitter. The fix was a M2 HSS slitter with a ta-C coating.

A Turkish service centre cutting 6 mm 304 stainless plate was getting 1,200 strokes from a D2 shear blade. The fix was M2 HSS at HRC 64, a 0.12 mm chamfer.

A European non-woven producer slitting 25 gsm spunbond at 600 m/min was getting 4 days from a D2 slitter. The fix was a M2 HSS slitter with TiCN coating.

A runnable cross-reference table for cold-work tool steel, high-speed steel, martensitic stainless and carbide grades. Find the equivalent of AISI D2, M2, M4.

AISI M2 is the workhorse high-speed steel of the converting and slitting industry. Molybdenum-tungsten-vanadium tool steel, hardened to HRC 62–65.

Corrugated slitting is one of the most abrasive industrial cutting applications. The substrate is a multi-layer composite of kraft paper + adhesive + flute.
