What Is CRKT's 1.4116 Stainless Steel ?

i think ive seen this steel number listed with puma's bowie knives,i wasnt sure if it was similar...
 
I don't know where the idea that this steel is somewhere between 440A and 440B would have come from. 1.4116 only has .45% -.5% carbon, well under even 440A and about the same as 420HC. It also only has about 14.6% chromium. All the 440 steels have between 16% and 18% chromium. It really looks more to me like it falls between AUS-4 and AUS-6. It is actually very similar in its chemical composition to 425M.
 
There is a list of german steels (including 1.4116). The list gives AISI equivalent, and DIN (german) notation.

For example,
AISI 440C is DIN X105 CrMo17 = 1.4125.

Steel-table
It is written in German but it is easy to follow the conversion of steel notations.

There is an error in the table: BG-42 is an US steel not swedish.

There does not seem to be a AISI eqivalent given for 1.4116. It has been positioned between 440A and 440B, but its chemical composition does not support that positioning. It is much closer to 1.4034 than it is to 1.4110.

The chemical compostion of 425M is: C .4% - .54%, Cr 13.5% - 15%, Mn .5%, Mo .6% - 1%, P .035%, Si .8%, V .1%.

For 1.4116 it is: C .45% - .5%, Cr 14.5% - 14.8%, Mn .4%, Mo .6%, P .02%, Si .4% - .6%, V .1%

My specs for 425M come from the Spyderco steel chart, and for 1.4116 come from the CRKT Steel Facts. The CRKT specs differ in those on the german site, but are close enough to tell me that 1.4116 is much closer to 425M than it is to either 440A or 440B.
 
Hmmmm.... I like Buck's 420HC. Maybe I should try the 1.4116 CRKT My Tighe. Looks interesting...
 
Anything with less than .5% carbon should be relegated to handle material IMO.

420HC is the absolutely lowest alloy steel I would consider for use in a blade.

The closest common US equivalent to 1.4116 is 420HC

However, Buck's proprietary heat treat leaves their 420HC blades at a Rockwell hardness of 58. Most other 420HC runs several points lower. Enough lower that I notice the difference in daily use.

Well, just by composition. 1.4125 is a tool steel where 440C is a ball bearing grade. There is a ball bearing grade with the same composition in the german list: 1.3543 X108CrMo17 / X102CrMo17 that compares more.
 
420HC equals to 4Cr13, the chemical composition is like 1.4034 grade. HRC 52-54.

1.4116 equals to 5Cr15MoV, in china we call 420MoV. HRC 55-57.
HRC is not very specific, it's related to heat treatment.

mini mill that uses mostly scrap might have too make weird batchs vs intergrated that make steel from iron

A MINI MILL IS TINY AND CHEAP, INTGRATED IS LIKE CITY AND EXPENSIVE. Why one has not been built in the USA since the 60's vs dozens of minis... nucor, beta, intek, steel dynamics etc. I know people that started all those.
 
This thread is 7 years old. I'm sure he is no longer interested in the question. Same as the other thread that was dug up about the same steel.
