1. Hōʻikeʻike
1.4122, commonly referenced by its European designation X39crmo17-1, is a martensitic chromium stainless steel designed to deliver a blend of paakiki, wear resistance and reasonable corrosion performance.
It occupies a practical middle ground between tool steels and corrosion-resistant stainless grades: hardenable by heat treatment to high strengths and abrasion resistance, yet offering better resistance to corrosion than many carbon steels.
