Hi All,
I've had 110X18M steel composition in the knife steel chart for over a year, and the source I've used was rosarmsusa page here - http://rosarmsusa.com/design.html
I did notice that English translation was not direct from the Russian, which would be 110X18MSHD, but I figured it was translation problem. Later on I was contacted by several individuals, and the info varied.
Some claim 110X18M is different from 110X18MSHD and other claim it is the same steel, but the composition I have is incorrect, specifically, Mo is not 3% but 0.80%. There's also 110x18 steel mention very often on many Russian knives sites, which is not listed anywhere in GOST standard, but as far as I understand it is accepted to be 440C equivalent.
I did some digging of my own and found few other sources, where they all have Mo 0.8%.
One of them is Rosarms Russian site here - http://www.rosarms.ru/index.php?aux_page=aux8_110x18m.html
Here's another link, which has most detailed composition and references to corresponding GOST documentatoin - http://www.naneve.ru/articles/4/12.doc and that one also lists 0.50-0.80% Mo.
Now I am a little confused and I hope someone can clarify situation.
First of all, what is the correct name if all those names refer to the same alloy, 110X18MSHD? 110X18M? 110X18? Are they all referring to the same steel?
Second, what's the correct Mo content for each (if they are different)?
http://rosarmsusa.com/faq.html page states 110X18 is equivalent of Latrobe's BG-42, but other sources claim 110X18MSHD to be analog of 440C. Based on the compositions, 110X18MSHD is much more similar to 440C based on chemical composition. 110X18M I have from Rosarms USA has 3% Mo, but the rest of the composition is identical to other sources.
Was 3% Mo just a typo? or those are two different steels after all?
