The Tempering Response Of Cpm® 3v Tool Steel Investigated Through Tensile Testing And Microstructural Observations, Stephen A.C. Hanson
Graduate Theses & Non-Theses
Heat treatment, tensile testing failure analysis, and microstructural evaluation of the Crucible Industries tool steel CPM® 3V was undertaken to investigate CPM® 3V’s tempering response for the following samples: As-Hardened (no tempering); tempered at 450°C, 550°C, 650°C, and 700°C; and As-Received (annealed). CPM® 3V tool steel is manufactured by Crucible Industries using their proprietary Crucible Particle Metallurgy (CPM®) technology. This material was heat-treated at four different tempering temperatures and was evaluated for tensile properties according to ASTM E8. A TMS landmark tensile fixture was used to establish the ultimate tensile strength and the yield strength of the material for the …
