covers
high-strength
low-alloy
structural
steel
shapes
in
Grades
50[345],60[415],and
65[450]
and
70[485],produced
by
the
quenching
and
self-tempering
process
(
QST
)

.The shapes are
intended for riveted or bolted construction of
bridges, buildings
and other
structures.

级别的高强低合金结构钢，通过淬火和
自回火工艺
(
QST
)
2
制造；这些型钢打算用铆钉和螺栓固定的桥梁建筑，高楼和其他建筑物
的型钢。
The QST process
consists of in line heat treatment and cooling
rate controls which result in
mechanical
properties
in
the
finished
condition
that
are
equivalent
to
those
attained
using
heat
treating processes which entail
reheating after rolling. A description of the QST
process is given in
Appendix X1.
淬火和
自回火处理程序在于热处理和冷却比率控制的完成条件下产生的力学性能，这个
过程相当
于那些利用热处理程序轧制之后再加热而产生的力学性能。
淬火和自回火处理程序
在附件
X1
中给了描述。
Due to the inherent characteristics
of the QST process, the shapes shall not be formed
and

at temperatures exceeding
1100

型钢。
When the
steel is to be welded, it is presupposed that a
welding procedure suitable for the
grade of steel and intended use or
service will be utilized. See appendix X3 of
specification A 6/A
6M for information
on weldability.
在钢结构焊接的时候，要假设钢铁的等级适合的焊接工艺并打
算利用的用途或服务。见
规范
A 6/A 6M
中附件
X3
中关于可焊接信息。
The
values
stated
in
either
inch-pound
units
or
SI
units
are
to
be
regarded
separately
as
standard. Within the text, the SI units
are shown in brackets. The values stated in each
system are
not exact equivalents;
therefore, each system must be used independently
of the other. Combining
values from the
two systems may result in nonconformance with this
specification.
值的描述在英制单位和国际制单位中任选其一作为标准，在文章中，在括号中写明国
际单
位制。
值的描述在每个体系中都没有确切的对应，
因此，
每个体系必须独立于其他，
两个体系值的混合可能会导致与此规范不一
致。
