## Description

The Knife Steel Composition Chart Chrome extension offers a detailed cross-reference database for knife steel alloys, including popular, exotic, and high-end materials used in blade making. Featuring over 6600 alloy names and more than 1035 distinct compositions, it covers 21 different national standards along with proprietary names and their equivalents.

Users can easily compare compositions using intuitive bar graphs in three different modes: mass percentage, molar masses, and atomic count per 1000 atoms. The extension supports bookmarking alloys, exporting and importing bookmarks, and viewing listings by standards, technologies, makers, countries, recently viewed items, and custom filters. Additionally, it provides explanations of alloying elements and their effects accessible within both the steel detail and graph views. This is a valuable tool for knife enthusiasts, makers, and metallurgists seeking a comprehensive and accessible steel reference database.
