26c3

Recommended Posts

Nicknamed Spicy White by Devin Thomas, this steel is either a White #1'ish with a pinch of chrome and slightly higher in manganese or a Blue #1'ish without the tungsten. More importantly, it is supposedly as clean as the Japanese steel.

I just ordered 18 pounds of it so I'm wondering if anyone here has worked with the steel. Either way, I'm going to do some test coupons of forged and stock removal for grain analysis and do some hardness tests on my new old machine. 

AKS recommends 1475°f with 10mins hold.

Oh well, Larrin just released test results on this steel.

Here's the numbers to remember. 

1475°f 10 minutes hold, quench in parks50 or equivalent.

Recommended 300-350°f temper for around 63-65hrc! Maximum temp is 450°f(for 61hrc). Above that, the toughness decreases due to tempered martensite embritlement. However, others steels like 52100 offer better toughness at this hardness level so 26c3 shines the most at very high hardness, just like White#1.
