Foreword
This document complies with the provisions of GB/T 1.1-2020 "Guidelines for Standardized Documents Part 1.Structure and Drafting Rules of Standardized Documents"
Drafting.
This document replaces GB/T 25821-2010 "Stainless Steel Strand". Compared with GB/T 25821-2010, except for structural adjustment and editing
In addition to sexual changes, the main technical changes are as follows.
---Changed the scope (see Chapter 1, Chapter 1 of the.2010 edition);
---Added the terms and definitions of "stainless steel strand" and "steel strand nominal cross-sectional area" (see 3.1, 3.2);
--- Added types of steel strand cross-section structures (see 4.1, 3.1 of the.2010 edition);
---Deleted the 1×3 steel strand section structure type (see 3.1 of the.2010 edition);
---Deleted the 1180MPa strength grade of steel strands (see 3.2 of the.2010 edition);
---Changed the twist direction requirements for the outermost steel wire of the steel strand (see 4.3, 3.3 of the.2010 edition);
---Changed the markup example (see 4.4,.2010 version of 3.4);
---Changed the allowable deviation of steel strand diameter (see Table 3, Table 1 of the.2010 edition);
---Changed the steel wire material grade (see 7.1.1, 6.1.1 of the.2010 edition);
---Changed the lay length requirements for steel strands (see 7.2.2, 6.2.2 of the.2010 edition);
---Changed the requirements for steel wire joints in steel strands (see 7.2.4, 6.2.4 of the.2010 edition);
---Changed the minimum breaking tensile strength requirements of steel strands (see Table 5, Table 3 of the.2010 version);
---Deleted the requirement for steel strand elongation and changed it to the requirement for steel strand elastic modulus (see 7.3.2, 6.3.3 of the.2010 edition);
---Deleted the requirements for the shape of the steel wire when cutting the steel strand (see 7.4 of the.2010 edition);
---Changed the product inspection rules (see Chapter 9, Chapter 8 of the.2010 edition).
