Foreword
This revised standard adopts ASTMB197/197M-01 "beryllium copper alloy wire."
This standard compared with ASTMB197/197M-01, except.
--- This standard specifies only the shape of a circular wire, ASTMB197/cross-sectional shape 197M-01 standard is circular, rectangular
Shape, square, hexagonal and octagonal wire;
--- This standard is based on ASTMB197/197M-01 on the increase QBe2 and QBe1.9 grades;
--- Diameter tolerances specified in this standard is stricter than ASTMB197/197M-01 standards;
--- Mechanical properties of the standard requirements than ASTMB197/197M-01 standard is slightly lower.
Instead of the standard YS/T 571-2006 "Beryllium line" (formerly GB/T 3134-1982).
Compared with this standard YS/T 571-2006, the main changes are as follows.
--- Expanding the scope of the standard; the new increase QBe1.9, C17200 and C17300 grade; raised some size to allow deviation
Accuracy; increase the weight limit of the reel; revised aging heat treatment process;
--- Increased supply state 1/4 hard (Y4), 3/4 hard (Y1), soft-aging (TF00), 1/4 hard Aging (TH01), 1/2 hard Aging
(TH02), 3/4 hard Aging (TH03) and hard aging (TH04);
--- Mechanical properties section, the 1/4 hard (Y4), 3/4 hard (Y1) performance and improve the performance range of cold state; increased
Tensile strength upper portion;
--- Test Method to the winding metal wire repeated bending test method.
Appendix A of this standard is the data appendix.
