Esr H13 Steel Remelted High Cleanliness Die Casting Stock - China

ESR H13 steel is the premium remelted version of the standard H13 hot work tool steel, produced by the electro slag remelting process that refines the ingot a second time under a protective slag layer.

Songshun Steel supplies ESR H13 for mould builders who need the highest possible internal quality, and this listing covers our stock forms plus technical guidance on when ESR is worth the upgrade.

The remelting step sharply reduces macro inclusions, porosity and center segregation while producing a much finer and more uniform carbide distribution than regular air melted H13 - For die casting dies this means measurably better resistance to heat checking, fewer polishing defects on visible casting surfaces, and more predictable life for core pins and inserts that see molten aluminium every shot cycle.

In glass moulds, aluminium extrusion tooling and hot forging dies, ESR H13 also shows less anisotropy, so big blocks behave the same in every direction.

Chemistry and hardness match the common H13 family, with annealed delivery at HB 229 max and working hardness from HRC 45 to 52 after quenching plus double tempering.

Typical customers choose ESR H13 steel for ultra smooth polishing work, thin rib and boss areas where ordinary grades crack first, large cavity blocks above 400mm, and any die where unplanned downtime costs more than the material difference.

We keep round bar from 100mm up to 400mm diameter and forged blocks to custom sizes, all tested ultrasonically to SEP 1921 with denseness grades documented on the certificate.

With almost 20 years of special steel experience, our engineer team will match your application to the right quality level between standard and ESR material.
