SU3JICT: Eard:sss Tas:s en A.36 Speci=e:s
Dear Reger:
Hard:sss tests were perfor:ad to da:ar isa t.e:he; the ca:erial sam,les which =eet the chemical requiremen: fe A36 =atarial also saa: the te:si"6 requireme=:s for this material. The raquire:ents include a d '-
and maximum tensile strength, s =itimu= yta*.d strength, and =i=1=us el::gaties requiram nts. These should be de:e;=1:ad by criaxial te:sile tests. lieverer, because of limitatiets on the as:= ef ca:arial available harhesa tes:s offered the culy naa s to esti=ata these pr:74::ies.
