ASTM A517/A517M A517 Grade F Material Machining Technology
ASTM A517/A517M A517 Grade F steel is a low-alloy quenched and tempered high-strength steel. This material has excellent mechanical properties due to its specified chemical composition and processing controls used during hot-forming and cold-working. The material has good formability and weldability, and is easily machinable. However, it may require greater tooling forces and cutting speeds than those used for conventional materials. ASTM A517/A517M A517 Grade F steel is most commonly heat treated with quench and tempering, which involves cooling it from an elevated temperature to below room-temperature and then tempering it by reheating it at a lower temperature for a specified time period.
