Ordering Information on Nitinol Wires and Tubes
Per ASTM F2063-12 or GB 24627-2009, ordering information or request for quotation should contain following info:
● Chemical composition or alloy code;
● Transformation temperature for the material at delivery status, such as Af
● Shape of the material such as bars, wires, tubing, or others
● Dimensions, such as diameter, OD & ID of tube, as well as their tolerances
● Heat Treatment status at delivery, such as Super-elastic, Cold Worked
● Surface status at delivery
● Mechanical Properties: When delivered in super-elastic state, upper plateau stress, tensile strength and elongation should be specified; when delivered in cold-worked state, tensile strength and elongation should be specified
● Quantity, such as weight, length, or number of pieces
