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。本数据表适用于由特殊结构钢N-A-XTRA制成的淬火和回火厚板。这种钢可分为三个不同等级，最小屈服强度分别为550、620和700 MPa（79.8、89.9和101）。 5 ksi）。有些等级的产品具有不同的韧性。这最后一种质量适用于在-40°C下具有最小冲击能量的低工作温度 厚度范围为3-120毫米（0.118-4.724英寸）的N-A-XTRA M级为（-40°F）。

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.This datasheet applies to quenched and tempered heavy plates made of the special structural steel N-A-XTRA. This steel can be supplied in 3 different grades with a minimum yield strength of 550, 620, and 700 MPa (79.8, 89.9, and 101.5 ksi). Some grades are delivered with different toughness properties. This last quality is for low service temperature with minimum impact energy at -40 °C (-40 °F) for grade N-A-XTRA M in a thickness range from 3-120 mm (0.118-4.724 in.).
