Foreword

This document was drafted in accordance with the provisions of GB/T 1.1-2020 “Directives for standardization - Part 1: Rules for the structure and drafting of standardizing documents”.

This document supersedes GB/T 37607-2019 “Corrosion-resistant alloy wire rod and wire” and GB/T 38589-2020 “General technical requirements of corrosion-resistant alloy bars, wire rods and wires”. This document is primarily based on GB/T 37607- 2019 and incorporates the content of GB/T 38589-2020.Compared with GB/T 37607- 2019, apart from structural adjustments and editorial changes, the main technical changes are as follows.

a) MODIFY the scope of application (see Clause 1 of this document; Clause 1 of the 2019 edition);

b) MODIFY the ordering contents (see Clause 4 of this document; Clause 3 of the 2019 edition);

c) MODIFY the delivery condition for wire rods (see 5.2.1 of this document; 5.3.1 of the 2019 edition);

d) ADD three corrosion-resistant alloy designations. H08330 (NS1105), H06690 (NS3105), and H06022 (NS3308); MODIFY the requirements for the chemical composition of certain designations (see 6.1 of this document; 5.1 of the 2019 edition);

e) ADD the requirements for the mechanical properties of wires of designations H08330 (NS1105), H06690 (NS3105), and H06022 (NS3308); MODIFY the requirements for the room-temperature mechanical properties of designation H10276 (NS3304); and MODIFY the recommended heat treatment regimens for the room-temperature mechanical properties of wires (see 6.2.2 of this document; 5.4 of the 2019 edition);

f) MODIFY the requirements for surface quality (see 6.3 of this document; 5.5 of the 2019 edition);

g) MODIFY the test methods (see 7.2 of this document; 6.1 of the 2019 edition);

h) MODIFY the provisions regarding packaging, marking, and quality certificate (see Clause 9 of this document; Clause 8 of the 2019 edition).

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. The issuing authority of this document shall not be held responsible for identifying any or all such patent rights.
