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。这些表以图形、图表和表格为特色，提供了有关成分或特性、物理和机械性能、热处理和可加工性的事实和数字。SAE 1021是一种锰含量相对较高的碳钢，与低锰碳钢相比，它提高了淬透性和硬度。 它结合了良好的机械加工性、良好的加工性（热加工或冷加工）和良好的焊接性。它在退火、热加工、正火、冷加工或水淬火和回火条件下用于许多应用。它可用于未渗碳应用和渗碳表面硬化的部件。

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.SAE 1021 is a carbon steel of relatively high manganese content which increases hardenability and hardness over that of carbon steels of lower manganese. It combines good machinability, good workability (hot or cold) and good weldability. It is used in the annealed, hot-worked, normalized, cold-worked or water-quenched-and-tempered condition for many applications. It may be used in uncarburized applications and for components case-hardened by carburizing.
