Water Hardening Steel

  • How to Harden Steel: 10 Steps (with Pictures) - wikiHow

    Aug 09, 2019· Often used to harden steels, water quenching from a temperature above the austenitic temperature will result in carbon getting trapped inside the austenitic lath. This leads to the hard and brittle martensitic stage. Austenite refers to iron alloys with a gamma-iron base, and martensite is a hard type of steel crystalline structure.
