What 2 % carbon buys
1.2436 (X210CrW12) carries 2.00–2.25 % carbon against D2’s 1.4–1.6 %. That extra carbon forms more chromium carbides, and carbide volume is what resists abrasive wear.
The trade is the same one that runs through the whole cold work family: as carbide volume rises, wear resistance improves and the ability to absorb impact falls. A die in 1.2436 will outlast D2 in a long blanking run, and it will chip where D2 would have survived.
When to move up
Move to 1.2436 when D2 dies are wearing out before the production run finishes and the failure is genuine wear — a polished, gradually enlarging edge — rather than chipping or cracking. If the D2 die is chipping, the answer is a tougher grade, not a harder one.
The heat treatment is less forgiving
Higher carbon means a narrower hardening window and more sensitivity to overheating. The austenitising temperature must be controlled, and the tempering schedule is the same two-window pattern as D2 but with less margin.
