6305

6305 VAC-ARC steel is a modified 4140 steel with higher molybdenum and a vanadium addition. The alloy is generally used in the 160-180 ksi (1103-1241 MPa) tensile strength range obtained with an 1100°F (593°C) temper where good toughness is critical. It is produced by vacuum consumable electrode re-melting process to provide optimum cleanliness and preferred ingot structure and used in applications where parts are subject to higher temperatures and material requires combination of good strength and toughness.
