Does anyone recognise the code EN15 engraved onto a rod of what I think is phosphor bronze?

they normally stamp a batch number on the end, but that number is a bit short ??

According to this:-

…it's a carbon manganese steel.

EH or EN 15 ? You have one in the heading, the other in the text.

[michael howarth 1Participant @michaelhowarth1]

Sorry Hopper…. and well spotted……it is EN15.

According to my copy of the Model Engineers Handbook EN15 is a plain carbon steel, modern designation 150M36.

This stuff is quite definitely not steel. I suppose the mark might be a local code.

Perhaps EN15 was the spec of the steel for the shaft to run in bushes made of the bronze you have? We can only speculate, I guess.
