Foreword
This document is drafted in accordance with GB/T 1.1-2020 "Directives for
standardization - Part 1: Rules for the structure and drafting of standardizing
documents".
This document replaces GB/T 28905-2012 "Low yield strength steel plates for
construction". Compared with GB/T 28905-2012, in addition to structural adjustment
and editorial changes, the main technical changes are as follows:
a) Change the maximum thickness of steel plate to 120 mm; add the coiled steel plate
with a thickness not greater than 25.4 mm (see Clause 1; Clause 1 of the 2012
edition);
b) Add LY300 designation and its corresponding technical requirements (see Table
1 and Table 2);
c) Change the chemical composition regulations of C and P; add the regulation that
intentionally-added alloy elements shall be indicated in the certification (see
Table 1; Table 1 of the 2012 edition);
d) In the delivery state, add the provision that delivery in other states can also be
made after negotiation between the supplier and the purchaser (see 7.3; 6.3 of the
2012 edition);
e) Change the yield strength ratio regulations of designations LY160 and LY225 (see
Table 2; Table 2 of the 2012 edition);
f) Add the regulations that surface defects of steel plates are allowed to be removed
by methods such as grinding AND welding repairs are not allowed (see 7.5.3 and
7.5.4);
g) Change the regulation on the minimum thickness of through-thickness
characteristics (see 7.6.3; 6.6.2 of the 2012 edition);
h) Add special requirements such as bend test, grain size, and nonmetallic inclusions
(see 7.6.2 and 7.6.5);
i) Change inspection lot regulations (see 9.2; 7.2 of the 2012 edition);
j) Add provisions on type of inspection document (see Clause 10).
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.
This document was proposed by China Iron and Steel Association.
This document shall be under the jurisdiction of National Technical Committee 183 on
Steel of Standardization Administration of China (SAC/TC 183).

Low yield strength steel plate for construction
1 Scope
This document specifies the designation representation method, order content,
dimension, shape, weight, technical requirements, test methods, inspection rules,
package, mark and certification of low yield strength steel plate for construction.
This document is applicable to single-rolled steel plates with a thickness not greater
than 120 mm and coiled steel plates with a thickness not greater than 25.4 mm for the
manufacture of building anti-seismic, shock-absorbing and other energy-dissipating
structural components (such as energy-dissipating damping components, etc.).
