15What is MrMO?
Thread Content
As title
Are you sure it’s 15MrMo and not 15CrMo?
It’s 15MrMo; I know that CrMo is a chromium-molybdenum alloy
There might be a mistake in the book; Mr. is not at all a chemical substance.
I’ve never heard of such a material.
15CrMo, it can be used under high pressure at high temperatures of 200°C, and is applied in ammonia synthesis
I think it’s a typo; it should be either 15CrMo or 15MnMo
It should be 15MnMu; the book wasn’t printed properly. The ‘n’ character has lost one of its legs: lol:lol:lol. It’s difficult to weld high-manganese steel.
