Knife Steel Composition Chart1.93 - App Store

Knife Steel Composition and name cross-reference database. Includes popular, high end and exotic alloys used in knife blades. Over 6500 alloy names, over 1000 compositions. Alloy names for 21 different international standards, proprietary names and their equivalents. Easy alloy composition comparison with bar graph in 3 modes: mass percentage, molar masses and atomic count per 1000 atoms.

If you have suggestions for improvement, please contact me. Posting in the review that there's a room for improvement doesn't help me at all, I am not a designer, but a software engineer.

Please report missing alloys, as in either post the alloy name, or contact me. Complaining in the review "I didn't find what I wanted" means very little.

If you encounter any problems using the app, please contact me using email. Posting in the review you have a problem, won't give me enough information to fix it.

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

Case CV has been the database for a long time. Search for Case does show in the results. Case isn't the steel maker though.
