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。CARPENTER SEVEN STAR是一种含钨的钼型高速钢。它与AISI M1型有一些相似之处；然而，其增加的碳和钒百分比（超过M1）在不显著降低其韧性的情况下提高了切割效率。七星是一种ESR（电渣重熔）高速钢。它的许多用途包括冲裁模、钻头、车床工具、冲头和剪切刀片。

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.CARPENTER SEVEN STAR is a molybdenum-type high-speed steel containing tungsten. It bears some similarity to AISI Type M1; however, its increased carbon and vanadium percentages (over M1) provide improved cutting efficiency without materially lowering its toughness. Seven Star is an ESR (Electro Slag Remelted) high-speed steel. Its many uses include blanking dies, drills, lathe tools, punches and shearing blades.
