Standard Specification for Seamless and Welded Ferritic and Martensitic Stainless Steel Tubing for General Service 通用无缝和焊接铁素体和马氏体不锈钢管标准规范
发布日期: 2024-03-01
1.1 本规范 2. 涵盖多个等级的标称壁厚不锈钢管,用于一般耐腐蚀和高温服务。这些级别中的大多数通常被称为“直铬”类型,其特征是具有铁磁性。其中两个等级,TP410和UNS S 41500( 表1 ),易于通过热处理硬化,并且高铬铁素体合金在缓慢冷却到常温时对缺口脆性敏感。在使用这些材料时应认识到这些特征。 表 1. 继续的 等级 TP439 . . . . . .

1.1 This specification 2 covers a number of grades of nominal-wall-thickness, stainless steel tubing for general corrosion-resisting and high-temperature service. Most of these grades are commonly known as the “straight-chromium” types and are characterized by being ferromagnetic. Two of these grades, TP410 and UNS S 41500 ( Table 1 ), are amenable to hardening by heat treatment, and the high-chromium, ferritic alloys are sensitive to notch-brittleness on slow cooling to ordinary temperatures. These features should be recognized in the use of these materials. TABLE 1 Continued Grade TP439 . . . . . . TP430 Ti TP XM-27 TP XM-33 A 18Cr-2Mo 29-4 29-4-2 26-3-3 25-4-4 . . . . . . .

Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. The inch-pound units shall apply unless the “M” designation of this specification is specified in the order. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
