Title:Nickel Alloy, Corrosion and Heat-Resistant, Sheet, Strip, and Plate, 72Ni - 15.5Cr - 0.95Cb(Nb) - 2.5Ti - 0.70Al - 7.0Fe, Annealed
Issuing Committee:Ams F Corrosion Heat Resistant Alloys Committee
Scope:This specification covers a corrosion and heat-resistant nickel alloy in the form of sheet, strip, and plate.
Product Code:SAE AMS3325
Title:Fluorosilicone (FVMQ) Rubber, Fuel and Oil Resistant, 55 - 65
Issuing Committee:Ams Ce Elastomers Committee
Scope:This specification covers a fluorosilicone (FVMQ) rubber in the form of sheet, strip, tubing, extrusions, and molded shapes.These products have been used typically for parts requiring resistance to jet fuel and lubricating oils, but usage is not limited to such applications. Generally, products are usable over a temperature range of -76 to +302 degrees F (-60 to +150 degrees C); each application, however, has to be considered individually.【英文标准名称】:StandardPracticeforIntegrityTestingofWaterFiltrationMembraneSystems
