Short answer: Martensite is the supersaturated, needle-like phase formed when austenite is quenched faster than it can diffuse — extremely hard and strong but brittle, which is why quenched parts are almost always tempered to recover toughness.
At a Glance
How Martensite Forms
Rapid quench traps carbon in a distorted lattice; it is the goal of Metal Induction Hardening Guide and links to Metal Austempering Guide, Stress Relieving Vs Annealing e Nitriding Vs Carburizing. View it under Metal Metallography Guide.
Strength & Risk
Hardness scales with carbon; toughness returns via tempering and Metal Recrystallization Temperature Guide context; avoid Metal Quench Cracking Guide and tie to Metal Creep Guide e Metal Fatigue Endurance Limit.
QA & Supply
Confirm hardness and structure by Metal Hardness Testing Methods, inspect per Metal Ndt Guide, and document per Mill Test Certificate Guide. HXSCO supplies hardening-grade steel.
