注：Tensile requirements for high strength cold drawn, as-delivered wire. Tensile strength can be increased by 29 ksi [200 MPa] up to 65 ksi [450 MPa] by tempering depending on tensile and tempering conditions. Recommendations: 840°F [450℃]/1~3 h for batch tempering; 950°F [500°C] for 3 to 10 minutes in a continuous conveyor furnace. Shorter times may result in uneven tempering.
During storage, the tensile strength will increase somewhat due to aging. Depending on the storage conditions, the tensile strength can Increase by 0~12ksi [0~80 MPa].
