1.2367 / X38CrMoV5-3 vs H11
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)
H11
Tool Steel
H11 is a 5% chromium hot work steel similar to H13 but with less vanadium, giving slightly higher toughness and deep air hardening. Used for hot forging, die casting and aerospace structural parts (as the 4340-alternative H11 mod in some specs).
