1.2344 ESR steel
Some friends asked me that any kind of steel would be same as 1.2344 ESR steel ,I thought H13 steel would be almost same as 1.2344 ESR steel
Some friends asked me that any kind of steel would be same as 1.2344 ESR steel ,I thought H13 steel would be almost same as 1.2344 ESR steel,I also discussed with some heat treatment factories engineers,they told me that both 1.2344 ESR steel and H13 steel processing of heat treatment are also almost same.For this kind of understanding,what I have to say is:don’t deem anything as our limited understanding,because of the “almost same”,it made us be disadvantage fooled many times,but we were never able to found the reason of been disadvantage fooled,though 1.2344 ESR steel and H13 steel are both belong to the hot work tool steel,but because different purification processes,different forging processes,different annealing processes,different test standard,the die steel will obtain difference result of the high temperature resistance、softening properties、wear resistance、crack resistance、toughness.

Applications
1.2344 Tool Steel is used in die casting dies for aluminium, magnesium and zinc, extrusion dies for aluminium and brass, liners, mandrels, pressure pads, followers, bolsters, die cases, die holders and adaptor rings for copper and brass extrusion. It is also for plastic moulds, shear blades for hot work and hot swaging dies. 1.2344 is also used in the production of hot stamping and press forge dies, split hot heading dies, gripper dies, hot punching, piercing and trimming tools.
