o wow i didnt even expect to get a respond but they are more used to working with d2 so they suggested that instead and said its less likely to rust andholds a better edge, and thank you for letting me know i really do appreciate it. be safe.
Well, it is a 12 year old thread...
what makes you say that and also now the choice is between d2 and 52100 bearing steel i really dont know to much would you say that the 52100 is the best and why 5160 instead of d2 d2 holds a better edge tho its not flexible is 52100 a great one to make a sword between 27 or 35
5160 over D2 in a sword.
52100 over D2 in a sword.
D2 in smaller blade if trying for more stsin resistance, 52100 if you want similar edge retention in a smaller knife with greater toughness and much easier sharpening than D2.
D2 toughness tops out at arround 5 foot lbs on the charpy test. CpmD2 which reaches about 12 foot/lbs due to the smaller carbide sizes attainable in that steel due to the CPM process.
52100 vs 5160 is a harder question. The heat treat on 52100 can be more complex, and it can't be made as tough as a 5160 blade (from the standpoint of topping out toughness). In a large blade like a 48 inch over all length it would depend on the maker, and his expertise with each steel.
Busse/Swamprat have done amazing things with 52100. (They call it Sr101 and have a proprietary heat treat.. I've personally used it, andand have seen it do things I found almost impossible to bkeave many times).
I have big choppers in 5160. I've had large choppers and fighting hawk in 52100.
52100 would get my nod for extra edge retention and 5160 a good jump in toughness. From a company like Busse with very precise hest treating cryo and tempering equipment and a lot of work dialing it in, I'd still take 52100 over 5160 from them.....
But 5160 is significantly tougher than 52100....
5160 has a toughness/ breaking force of 45 foot/lbs
52100 tops out at about 30 foot/lbs.
If I was planning on using the sword like a caveman I'd get one in 5160 (or an even tougher steel like 3V, but cost increases a lot, and billets in longer length are are harder to source and more expensive).
(Busse /Swamp Rat make caveman proof knives and swords from it, and many many custom makers use 52100 as their go to steel for forged and stock removal knives).
D2 is a lovely steel for pocket knives and small to medium sized users. I would not choose it for even a large chopping knife. With a polished finish it is less prone to staining. Has large carbide, which give it decent edge retention, but make it easier to fracture and harder to sharpen. Diamond stones work great.
Here is a great link to an invaluable website for comparing steels, properties, stainless, toughness, edge retention, etc.
