D2 vs SKD11: Are They the Same Steel?
AISI D2 and JIS SKD11 are the most-quoted cold-work tool steels in industrial blade manufacturing. They share a spec sheet — but the heat treatment.

AISI D2 and JIS SKD11 are the most-quoted cold-work tool steels in industrial blade manufacturing. They share a spec sheet — but the heat treatment.

JIS SKD11 is the Japanese standard cold-work tool steel, chemically equivalent to AISI D2 but with a tighter vanadium range and typically tighter stock.

Paper slitting looks simple until you account for the substrate GSM, the caliper variation, the trim, the lay-flat tension and the line speed.

A structured method our engineers use to match substrate, geometry, hardness target, edge preparation and operating speed to a production line — without.
