Annealing Temp. in Deg.E (IHr.at Temp.) 



Chart 119. — The effect of annealing on the tensile strength and 

 apparent elastic limit of deep-drawing brass strip, previously cold- 

 rolled 6 B. & S. Nos. (50 per cent reduction of area) from two different 

 grain sizes, 0.015 and 0.100 mm. (68.41 % copper) (0.040-in. stock).
