British Material Specification
British Material Specification
(OP)
I am looking for an equivalent "American" steel for BS 970605M36T. I looked through the Metals Black Book and searched around the internet but could not find anything on this spec. I am looking into this for someone else and they tell me it is a British standard that is called out on a gear drawing. Does anyone have any info on this spec. or can someone point me to someplace that has it?
Thanks for your help

BS 970 1970 states : harden in oil from 840 - 870 C. Temper at a suitable temperature between 550 and 680 C.
Worldwide guide to equivalent irons and steels 3rd edition lists AISI 4032 in the same group - 0.3 -0.35%C 0.7- 0.9 Mn, 0.2 - 0.3 Mo, 0.035 max S, 0.04max P, 0.2 - 0.0.35 Si, but no mech props listed.
