D2 steel equivalent Cr12MoV, is China standard cold work tool steel. Cr12MoV is equivalent for DIN 1.2379, AISI D2, JIS SKD11, and grade K110. Many customer purchase OTAI Steel supplied Cr12MoV as D2 steel equivalent, main reason is Cr12MoV have similar chemical composition and performance, but price is much cheaper. This article will explain the reason step by step.

D2 steel equivalent

Cr12MoV chemical composition comparison with D2, 1.2379, and SKD11

Below tables show D2 steel equivalent chemical composition for each grade, most composition is very similar, Mo and V contents have more or less difference for different grade. Hardness after annealed is the same.

Grade C Si Mn S P Cr Mo V Annealed Hardness (HB)
Cr12MoV 1.45-1.7 ≤0.40 ≤0.40 ≤0.03 ≤0.03 11-12.5 0.4-0.6 0.15-0.3 207-255
D2 1.4-1.6 0.1-0.6 0.1-0.6 ≤0.03 ≤0.03 11-13 0.7-1.2 0.5-1.1 255
1.2379 1.5-1.6 0.1-0.4 0.15-0.45 ≤0.03 ≤0.03 11-12 0.6-0.8 0.9-1.1 250
SKD11 1.4-1.6 ≤0.40 ≤0.60 ≤0.03 ≤0.03 11-13 0.80-1.2 0.2-0.5 ≤255

The reason to use D2 steel equivalent Cr12MoV

1. Mechanical performance for Cr12MoV and other D2 steel equivalent are similar.

Under the same manufacturing process, if chemical composition similar, the mechanical performance is also similar. OTAI Cr12MoV is directly supply by top three China mill, strictly follow standard GBT1299-2000YB

2.Price for Cr12MoV is much cheaper compared other D2 steel equivalent 1.2379, SKD11 and D2

Generally speaking, Cr12MoV price is cheaper 1300-1800$/Ton compared D2 and 1.2379. If your final product can use Cr12MoV, can save huge cost.

3.Cr12MoV is the most widely used cold work tooling steel in China, usage is huge, more often used than other D2 steel equivalent

In China, we use Cr12MoV to make knives, cutting tools, just like in the United states, use D2, in Europe use 1.2379. Similar application can use similar material of course, so normally used tooling steel in China also can normally used in worldwide, but the time is accept might be very long. To change people’s mind is not easy job.
