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。COLUMBIA SPECIAL是制造商质量最高、等级最好的水硬化工具钢。它含有少量的铬和钒。其制造受到严格控制，以确保均匀可预测的淬透性。当盐水淬火时，它会形成一个均匀的中等深度的高硬度外壳，带有一个坚硬的减震芯。它以高耐磨性和高韧性的结合而闻名。COLUMBIA SPECIAL的许多应用包括多种用途的模具、铰刀、丝锥、钻头、冲头、量规和木刀。

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.COLUMBIA SPECIAL is the manufacturer's highest quality best grade of water-hardening tool steel. It contains small amounts of chromium and vanadium. Its manufacture is controlled closely to insure uniform predictable hardenability. When brine quenched it develops a uniform high-hardness case of medium depth with a tough shock-dampening core. It is noted for its combination of high resistance to abrasion and high toughness. COLUMBIA SPECIAL'S many applications include dies for many uses, reamers, taps, drills, punches, gages and wood knives.
