Product Code:SAE AMS5225
Title:Iron-Nickel Alloy, Strip, 49Fe - 5.3Cr - 42Ni - 2.5Ti - 0.55Al, Solution Heat Treated, Cold Rolled, 50% Reduction
Issuing Committee:Ams F Corrosion Heat Resistant Alloys Committee
Scope:This specification covers an iron-nickel alloy in the form of strip.This strip has been used typically for diaphragms, leaf springs, and helical springs, requiring a precipitation-hardenable alloy with a temperature coefficient of modulus of elasticity of -20 to +20 x 10-6 per degree Fahrenheit from -50 to +150 掳F (-36 to +36 x 10-6 per degree Celsius from -46 to +66 掳C) after suitable heat treatment, but usage is not limited to such applications.【英文标准名称】:Luminaires-Part2-23:Particularrequirements-Extralowvoltagelightingsystemsforfilamentlamps
