查看样本合金摘要数据表（PDF）自1952年以来，合金摘要一直是世界各地使用的金属和合金材料性能数据的主要参考。以图表、图表和表格为特色，这些表格给出了有关成分或特性、物理和机械性能、热处理和可加工性的事实和数字。坩埚S7 XL是一种双精炼高纯度等级的S7工具钢（见合金文摘TS-543），专门设计用于简化线切割加工（EDM）操作，提高塑料注射模具纹理化的一致性，与传统S7相比具有优异的抗冲击性。 典型应用包括塑料注射模具、线切割冲头和模具，以及重型冲击工具。

View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.Crucible S7 XL is a double-refined high-purity grade of S7 tool steel (see Alloy Digest TS-543) designed specifically for ease of wire electrical discharge machining (EDM) operations, improved consistency in texturizing of plastic injection molds, and superior shock resistance compared to conventional S7. Typical applications include plastic injection molds, punches and dies by wire EDM, and heavy impact tools.
