Product Code:SAE AMS5520
Title:Steel, Corrosion and Heat-Resistant, Sheet, Strip, Foil, and Plate, 15Cr - 7.1Ni - 2.5Mo - 1.1Al, Solution Heat Treated, Precipitation Hardenable
Issuing Committee:Ams F Corrosion Heat Resistant Alloys Committee
Scope:This specification covers a corrosion and heat-resistant steel in the form of sheet, strip, foil, and plate.These products have been used typically for parts requiring corrosion resistance and high strength up to 600 °F (316 °C) and where such parts may require welding during fabrication, but usage is not limited to such applications.Certain design and processing procedures may cause these products to become susceptible to stress-corrosion cracking; ARP1110 recommends practices to minimize such conditions.【英文标准名称】:Postalservices-Qualityofservice-Measurementofthetransittimeofend-to-endservicesforbulkmail(includesAmendmentA1:2007);EnglishversionofDINEN14534:2007-06
