D2 Alternatives: Choose the Right Tool Steel by Failure Mode A good D2 alternative should solve the actual failure problem. If D2 wears out without cracking, the replacement should improve wear resistance. If D2 chips or cracks, the replacement should improve toughness. If D2 deforms under load, the replacement should improve hardness, compressive strength, or […]

D2 Equivalent Material: 1.2379, SKD11, Cr12Mo1V1 and Other Matching Grades D2-equivalent material usually refers to a D2-type cold-work tool steel supplied under another national or regional standard. The most common equivalent grades are DIN 1.2379, EN X153CrMoV12 / X153CrMoV12-1, JIS SKD11, and GB Cr12Mo1V1. These grades belong to the same high-carbon, high-chromium cold work tool
