About this app

If you have relevant information, please share with me and I'll publish it.

Over 6600 alloy names, over 1035 compositions. Alloy names for 21 different national standards, proprietary names and their equivalents. Easy composition comparison with bar graph in 3 modes: mass percentage, molar masses and atomic count per 1000 atoms.

App needs 2mb space on the device, regardless of install location!!!

Sorry, there will be no translations to any language. I am one person collecting steel data and coding the app on 3 platforms. I have neither time nor resources to keep constantly translating large database.

You can help by reporting missing alloys, and incorrect info. That's a lot more helpful than leaving utterly useless "I didn't find what I wanted" comments, what do you expect me to do anyway, dream up what was it you didn't find? 99% of the times people are mixing up knife brand names with steel names, I can clear that much up if anything else.

App is no longer distributed in Russia, due to the excessive amount of complaints and bad ratings, all because I can't translate to Russian, even though app's Russian description did explain why I can't.

Ratings and reviews

This app has become my go-to trusted resource for comparing various knife steels. It's simple, easy to use, and serves as a great quick reference app when buying any kind of knife. I like to know exactly what I am buying when shopping for knives, as there are A LOT of disreputable companies that will try to pass off 440 stainless steel as "Premium" and charge hundreds of dollars for a set that is functionally identical to something you could get at Dollar General.

It's great to have an app that gives you the content of the many steel components that are used in knives, old and new. It has most all steels for blades of nearly any you might have, are looking for and are wanting to know more about, with cross references from other countries and Maker's. For me it's priceless to have this app. I personally love it!!!

as a knife collector and user this app is the most informative information on different types of steel, totally awesome. thank you, this app is absolutely the best for keeping up with all of these new and exotic blade Steel. this app is the best there is, try it you will not be disappointed 🇺🇸...
