Material Notes:

Crucible S7XL is a double refined, high purity grade of S7. The remelt operation produces a cleaner steel with a more uniform microstructure, offering the following advantages over conventional S7:Better Consistency in Wire EDM CuttingHigher Polishability for Critical Finish Plastic MoldsMore Uniform Texturing for Plastic MoldsHigher Transverse Impact Toughness (Across the Grain) Crucible S7 XL can be used in any application where AISI S7 is used.Information provided by Crucible Specialty Metals.
