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。合金19D（UNS S32001）是一种贫双相（铁素体奥氏体）不锈钢，由AK steel开发并获得专利，注册商标为Nitronic 19D。与传统的双相和超双相不锈钢相比，合金19D的铬含量降低，大部分镍被man ganese替代，钼基本上被消除。吉布森管道公司进行了一项开发计划，以生产缝焊19D管道。（参见参考文献1和2。）缝焊19D海底脐带管的交付始于2000年夏天。

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.Alloy 19D (UNS S32001) is a lean duplex (ferritic-austenitic) stainless steel developed and patented by AK Steel and registered as the trade-mark Nitronic 19D. Compared to conventional duplex and super-duplex stainless steels, alloy 19D has a reduced chromium content, man-ganese is substituted for most of the nickel, and molybdenum is essentially eliminated. Gibson Tube conducted a development program to produce seam-welded 19D tubing. (See Ref 1 and 2.) Delivery of seam-welded 19D subsea umbilical tubing began during the summer of 2000.
