Despciption

hardening in aeir, featuring a fine conbination of  hot strength, heat cracking resistance and impact toughness in work 600°c ESR products macrostructure will EFER steel had cleaness evidently ERS had all higher ISO directivity.

Application

Extrusion dies and die-casting for alumium, mandgnesium allay mostly, for copper alloy could use mechanical press forhing of steel, could use AISO
