This is getting a little off topic, but while most of the information in the excerpted post above is correct to my knowledge, there are some statements that are incorrect or misleading. I'm neither a metallurgical engineer nor a historian of Reynolds 531, so I hope that the better informed will chime in to confirm or refute my take on the following:
- (Of note, when iron is mixed with more than 2.1% carbon it is no longer "steel", it goes by the name "cast iron".)
I don't dispute that cast iron contains 2.1% or more carbon, however, it doesn't follow that all such alloys are necessarily "cast iron".
- In 1953 the Reynolds Cycle Company began manufacturing a steel tube composed of proprietary manganese-molybdenum steel alloy they branded Reynolds 531.
I always thought Reynolds 531 was developed before WWII. Maybe just a typo on the year?
