1.2367 / X38CrMoV5-3 vs 1.2365 / 32CrMoV12-28
These two grades are listed as equivalents of each other: their chemistry windows overlap and they serve the same applications. They are not always identical — check the differences below before substituting, especially in certified designs.
1.2367 / X38CrMoV5-3
Tool Steel
1.2367 is a modified H11-type hot work steel with the molybdenum raised to about 3%, closing most of the hot-strength gap to 1.2365 while keeping H11-class toughness. In ESR quality it is a premium die-casting and forging die steel for tools that crack or heat-check in standard H13.
Standards: DIN 1.2367 · AISI — (modified H11 type)
1.2365 / 32CrMoV12-28
Tool Steel
1.2365 is the high-molybdenum hot work steel of the H10 family: nearly 3% Mo buys outstanding tempering resistance and hot strength for tools that stay hot for a long time, such as brass extrusion and copper alloy die casting tooling. It trades a little toughness for that hot hardness.
