Comandante Grinder - Nitrogen Steel

[atv223]

So I stumbled upon this high end manual coffer grinder.

The description says:

Manufacturing a Nitro Blade is a serious engineering task which requires special tools and machinery, excellent craftsmanship and lots of experience. High-nitrogen martensitic steel is extremely difficult to work with. But when finished, it is tough, highly wear resistant and has a high degree of edge retention. This is what we want.

Got me wondering if it's H1, LC200N or some other nitrogen variant.

Anyone have insight? Just curious.

I dont think h1 is classified as martensitic so probably not it.

It could be a number of steels but...

Lc200n=zfinit=cronidur 30
Cronidur 30 I think was the first nitrogen steel on the market, so theres a good chance it could be it.

I would be surprised if the burrs are manufactured by Comandante themselves, but haven’t been able to trace a supplier (probably Italian) online.

Knock/Aergrind says their Italmill burrs should last 1kg per week for 10 years plus, which is a lot of coffee through a small hand grinder.

Italmill say they use 18NiCrMo5, 17NiCrMoS6-4 & K110 / X155CrVMo12

When you find out, it may be a let down. It reminds me of all the names applied to various steels as a marketing ploy.
